Electric heating heat conduction oil boiler diesel burner

The electric heating heat transfer oil boiler diesel burner is also called the electric heating heat transfer oil furnace light oil burner, which usually uses heat transfer oil It is a heat transfer medium and uses a circulating pump to circulate the hot oil in a liquid phase, thereby transferring heat to the heat-consuming equipment, and then returning to the heater through the circulating pump, so that the continuous heat transfer is performed repeatedly and accurately controlled The temperature of the device. So let's briefly introduce it below. 1. Advantages of electric heating heat-conducting oil boiler diesel burner 1. Compact and scientific appearance design: This product adopts cabinet design style, beautiful appearance and compact internal structure, which is an ideal choice for saving space. 2. Unique internal structure design: the electric heating tube is connected with the furnace body and flange, which is conducive to replacement, repair and maintenance. 3. Precise temperature control system: users can adjust the temperature from room temperature to 200 degrees as needed, which makes users more intimate. Temperature control accuracy ±0.1℃4, one-step electronic control system: the boiler diesel burner operating system is fully automatic control, all control parts are concentrated on a computer control panel, only need to connect water and electricity during operation. Press the key, the boiler diesel burner will automatically enter the fully automatic operation state, which is safer and more worry-free. 5. Multiple interlocking safety protection functions: The product is equipped with a vent to prevent the boiler diesel burner from generating pressure and causing an explosion accident; at the same time, it has low water level protection. When the water supply is stopped, the boiler diesel burner will automatically stop working, preventing the boiler The dry burning of the diesel combustion engine leads to damage or even burnout of the electric heating element. The leakage protector makes the safety of operators and equipment more secure. Even in the case of circuit short circuit or leakage caused by improper operation of the boiler diesel burner, the boiler diesel burner will automatically cut off the circuit to protect the operator and control in time The safety of the line. The use of electric energy is more environmentally friendly and economical: electric energy is absolutely pollution-free and more environmentally friendly than other fuels. Using low-valley electricity can greatly save equipment operating costs. 2. Working principle and characteristics of light oil burner of electric heating heat conduction oil furnace Electric heating heat conduction oil furnace light oil burner (organic heat carrier furnace) is a new type of safety, energy saving and high efficiency developed on the basis of absorbing foreign advanced technology , Low pressure, special explosion-proof industrial furnace that can provide high temperature heat energy. The furnace is a kind of electric energy as the heat source, that is, the tubular electric heating element immersed in the heat transfer oil is energized to generate heat, the heat transfer oil is used as the heat carrier, and the heat is forced to circulate through the hot oil circulation pump to transfer the heat to one or several heat consumers. equipment. For the heat transfer oil electric heater, the heat is generated and transmitted by the electric heating element immersed in the heat transfer oil. The electric heating heat transfer oil furnace light oil burner uses heat transfer oil as the medium and uses a circulating pump to force the heat transfer oil to circulate in the liquid phase. , Transfer heat to one or more heat-using equipment. After the heat-using equipment is unloaded, it is a kind of electricity that uses electric energy as the heat source to pass through the circulating pump again to the heater, and then absorb the heat, transfer it to the heat-using equipment, and electric heating The heat-conducting oil furnace light oil burner repeats this cycle to realize the continuous heat transfer and increase the temperature of the heated object to meet the heating process requirements. After being unloaded by the heat equipment, the heat transfer oil passes through the circulating pump again, so that the continuous heat transfer is realized. Ensure that thermal equipment can be used to obtain continuous and stable high-temperature energy. Meet the process requirements of medium heating. The thermal oil electric heater can be controlled by a digital display temperature controller. 3. The advantages of electric heating heat conduction oil boiler diesel burners compared with gas boiler diesel burners. Currently, under the promotion of national environmental protection policies, companies that originally used fuel oil and coal for heating have begun to consider switching to clean energy. Including electricity, natural gas and biomass, among which electricity is particularly important. Analyze several common heat-conducting oil furnace light oil burners and take a look at the characteristics of electric heating heat-conducting oil furnace light oil burners. Analysis of Gas Boiler Diesel Combustor: As a process equipment that generates heat and power, gas boiler diesel combustor is widely used in electric power, machinery, chemical industry, textile and papermaking industries, hotels, residential areas, etc. for heating and heating. Due to the need for heating in northern cities in my country, a larger number of mold temperature machines are in use. Gas mold temperature controllers have gradually entered people's lives. The accidents that occur in the operation of gas boilers and diesel combustion engines can be roughly pided into three categories: 1. Extraordinary accidents: The main pressure parts in the mold temperature machine-pipelines, etc., rupture and explode. Such accidents often lead to equipment and workshops. Damage and personal injury, causing heavy losses. 2. Major accidents: accidents where the gas mold temperature controller cannot maintain normal operation and forced to shut down the furnace, such as dry burning accidents, furnace explosion accidents, etc. Although this type of accident is not as serious as a catastrophic accident, it often causes damage to equipment, workshops, personal injuries, and forced shutdown of the gas mold temperature machine, resulting in partial or complete shutdown of the steam-using department, resulting in serious economic losses. 3. General accidents: accidents that can be eliminated during operation or accidents that can be eliminated after a short period of time out of the furnace will have less impact and loss. The gas mold temperature machine accident belongs to the explosion accident that caused the largest loss among the three main types of industrial thermal disasters. Mainly can be pided into two kinds of explosion causes, one is furnace explosion, the other is furnace explosion. The gas mold temperature machine has a high frequency of explosion accidents. In contrast, the risk of electric mold temperature control is much smaller. Hazardous characteristics of gas The fuel of the gas temperature controller is combustible gas, mainly natural gas or coal gas. The main components of natural gas and coal gas are methane, and some simple alkanes are mixed. These components are highly flammable and explosive gases. The lower explosion limit of natural gas is 4%, and the lower explosion limit of coal gas is 6.2%, which is very easy to explode. accident. Furnace explosion fire hazard Furnace explosion is caused by the leakage of combustible gas and mixing with air to form an explosive mixture. When this mixture is in the explosive limit range, an explosion accident will occur when it comes into contact with a suitable ignition source. Accompanied by chemical changes, the gas pressure in the furnace increases instantaneously, and the resulting explosive force exceeds the strength of the structure, causing an outward explosion. Because a large amount of energy accumulates in a limited volume in a very short time, the furnace of the mold temperature machine is in an extraordinary High pressure or high temperature conditions cause the surrounding medium to vibrate or nearby materials are destroyed. The furnace explosion is mainly caused by the following factors. 1. Improper ignition During ignition, such as improper start operation, flameout occurs and the gas source is not cut off in time, the gas distribution pipe is not cut off in time for combustible gas purging, or the purging is incomplete, the nozzle does not ignite or is blown out when the valve is opened. Or other situations that may accumulate a large amount of high-concentration combustible gas in the furnace and within the explosive limit range, then the combustible gas will be ignited when re-ignited, causing an explosion. 2. The flame is unstable and extinguished. If the output of the gas burner is too large, the flame will separate from the burner, and an out-of-fire phenomenon will occur: On the contrary, if the output is too small, the flame will retract into the burner, causing a backfire phenomenon, and the mold temperature When the machine is running, the flame is unstable and goes out. Because the furnace is in a hot state, it reaches or exceeds the ignition temperature of the combustible gas and air mixture, and when the combustible gas continues to enter, an explosion may occur immediately. Electric heating heat conduction oil furnace light oil burner analysis: Electric heating heat conduction oil furnace light oil burner saves energy: low operating cost The heat conduction oil heating system is a liquid phase closed loop, and the difference between the oil outlet temperature and the return oil temperature is 20-30 degrees. That is to say, only heating the temperature difference of 20-30 degrees can reach the use temperature. At the same time, the equipment does not require water treatment equipment and there is no heat loss such as running, emitting, dripping and leaking of the steam boiler diesel burner, and the heat utilization rate is very high. Compared with the steam boiler diesel burner, it saves about 50% of the electric heating heat transfer oil. Low investment in heating equipment for furnace light oil burner: Due to the simple heat conduction oil heating system, no water treatment equipment and more auxiliary equipment, boiler diesel burners withstand low pressure, etc., the entire system has less investment; safety: due to electric heating heat conduction The oil burner light oil burner system only bears pump pressure, and the heat transfer oil heating system has no risk of explosion, so it is safer. Environmental protection: The environmental protection effect of the heating system of the light oil burner of the electric heating heat conduction oil furnace is mainly reflected in the minimal flue gas emissions, no pollution and thermal pollution, and meeting environmental protection requirements. Electric heating heat conduction oil furnace and light oil burner are widely used: high temperature setting, sheet heating, rubber, drying, printing and dyeing, chemical industry, plywood production, waterproof coil production, asphalt heating, non-woven hot rolling mill, FRP hot pressing machine , Molds, drying rooms, ovens and other industries that require heat. Fourth, the introduction of thermal conductive oil The English name of thermal conductive oil: Thermal conductive oil. The heat transfer oil has the properties of resistance to thermal cracking and chemical oxidation, good heat transfer efficiency, fast heat dissipation and good thermal stability. As an industrial oil heat transfer medium, heat transfer oil has the following characteristics: Under almost normal pressure conditions, it can obtain a very high operating temperature. That is, the operating pressure and safety requirements of the high-temperature heating system can be greatly reduced, and the reliability of the system and equipment can be improved; it can meet the process requirements of heating and cooling at different temperatures in a wider temperature range, or use the same type in the same system The heat transfer oil realizes the process requirements of high temperature heating and low temperature cooling at the same time. That is, the complexity of the system and operation can be reduced; the water treatment system and equipment are omitted, the thermal efficiency of the system is improved, and the maintenance workload of the equipment and pipelines is reduced. That is, the initial investment and operating costs of the heating system can be reduced; in the case of system leakage caused by the accident, the heat transfer oil may burn when it meets the open flame. This is the problem of the heat transfer oil system compared with the water vapor system. But under the condition of no leakage, because the heat transfer oil system works under low pressure conditions, its operational safety is higher than that of water and steam systems. Compared with another type of high-temperature heat transfer medium molten salt, when the operating temperature is above 400℃, the molten salt has an absolute advantage over the heat transfer oil in terms of the price and service life of the heat transfer medium, but it is in other aspects. Obvious disadvantages, especially in the complexity of system operation. V. Electricity consumption of electric heating heat transfer oil boiler diesel burners Due to the domestic emphasis on environmental protection and production safety, more and more users will consider choosing electric heating heat transfer oil boiler diesel burners instead of boiler diesel burners. Electric heating heat conduction oil burner light oil burner is a heat energy conversion device driven by electricity. It heats the heat conduction oil through electronic components, so as to achieve effective heat transfer. Its advantage of relying on electric power also makes it widely favored by people as soon as it goes on the market, but many people do not understand its power consumption. So which parts of the electric heating heat conduction oil burner light oil burner are mainly consumed? Will it cause waste? Let's do the calculation of the power consumption of the light oil burner of the electric heating heat transfer oil furnace: Take a 60KW oil furnace as an example, 1. The pump power is 5.5KW, the set temperature is reached in 1 hour, and it runs for 8 hours a day. 2. Constant temperature: to maintain temperature balance, the heating tube of the electric heating oil furnace works intermittently, usually accounting for 30% of the total power, and the power consumption per hour is 18KW. This data is related to the heating tube, use environment, and heat dissipation conditions. The greater the heat dissipation, The actual power consumption is greater. 3. Circulating pump: The power of the pump is 5.5KW, and the power consumption is 44KW in 8 hours. It can be calculated that the daily electricity consumption of the electric heating oil furnace is 248 kilowatts. According to the actual electricity price, the daily electricity consumption cost can basically be calculated. Through the above calculation, it can be seen that if the electric heating type heat conduction oil burner light oil burner needs to save electricity, it can be solved by the following ways: 1. If economically permits, it is recommended that the electric heating tube adopts SCR control. The power consumption can be controlled to a minimum level. 2. The frequent pull-in of the mold temperature machine’s contactor impacts the power grid. It is recommended to use solid state relays or thyristor control. 3. Improve the efficiency of the heating tube, reduce the heating time 4. Reduce heat dissipation, Avoid waste of heat and minimize the power of the circulating pump. 6. The principle of electric heating converts electrical energy into thermal energy to heat objects. It is a form of electric energy utilization. Compared with general fuel heating, electric heating can obtain higher temperature (such as arc heating, the temperature can reach 3000 ℃ or more), easy to realize automatic temperature control and remote control, and can maintain a certain temperature distribution of the heated object as required . Electric heating can directly generate heat inside the heated object, so it has high thermal efficiency and fast heating speed. According to the heating process requirements, it can realize uniform heating or local heating (including surface heating), and it is easy to realize vacuum heating and controlled atmosphere heating. In the process of electric heating, there is little waste gas, residue and smoke, which can keep the heated object clean and not pollute the environment. Therefore, electric heating is widely used in fields such as production, scientific research and testing. Especially in the manufacturing of single crystals and transistors, mechanical parts and surface quenching, smelting of ferroalloys, and manufacturing of artificial graphite, electric heating methods are used. Seven. Operating procedures for cleaning the diesel burner of the electric heating heat transfer oil boiler 1. Drain the old oil: Use the heating system to heat the heat transfer oil to 70-80℃, and discharge all the heat transfer oil in the system while it is hot. According to the conditions, Let the residual oil in the system be released as much as possible. Add a small amount of cleaning agent that can not be released to make the oil thin by penetration, stripping, and dissolution, and then discharge it out of the system. 2. Pre-washing: Add 2% (70-80 kg, a bag of semi-solid, and a bucket of semi-liquid) of the cleaning agent into the system, dissolve the solid with hot water, and add the liquid at the same time. Any part of the thermal system (usually through the oil pump through the high-level oil tank, the same way as refueling) is put into the system, fills the system with clean water, turns on the circulating oil pump to circulate, uses the heating furnace to raise the water temperature to 80℃±5℃, switch The relevant valve of each reactor in the system allows all parts in the system to be circulated separately. After 6 to 8 hours (if there are more reaction kettles, you need to increase the pre-washing time, and make each kettle circulate separately for half an hour), open all the low-position drain valves of the system to drain the water in the system. Then re-inject water to rinse, heating (80℃±5℃) while rinsing has the best effect, until the water becomes clear, or the slightly yellow PH value is the same as that of water. 3. Cleaning: The cleaning agent is adjusted to the total circulation 6～8% of (in order to ensure the effect, please reserve 50 kg, one bucket and one bag) into the system, after the solid is dissolved in hot water, the liquid is added at the same time, the same as (2) into the system, and fill the system with clean water, then turn on The circulating pump circulates, using a heating furnace to heat the cleaning agent to 90°C ± 5°C. Switch the valve of the system so that all parts in the system can be cleaned. It is advisable to switch the valve every hour. The entire cleaning time is not less than 24 hours (if there are more reactors, the pre-washing time needs to be increased). Open the cleaning of any part of the circulation pipeline to check the cleaning. If there is still grease, increase the cleaning time until all is peeled off and enter the next step. 4. Water washing①: Fill the system with clean water, turn on the circulating pump to circulate, use the heating furnace to raise the water temperature to 90℃±5℃, switch the relevant valves in the system, so that all parts in the system are circulated separately. Rinse the system. After three hours, open all the low-position drain valves of the system to drain the water in the system. 5. Water washing ②: Fill the system with clean water again, and turn on the circulating pump to circulate, use the heating furnace to raise the water temperature to 90℃±5℃.
