Gas thermal oil boiler diesel burner and supporting equipment

The gas-fired heat-conducting oil boiler diesel burner uses gas, burning fuel, and the burner and heat-conducting oil as the heat carrier. Generally pided into vertical and horizontal structures, mainly based on the height of the equipment space. 1. The heating surface of gas-fired heat-conducting oil boiler, diesel combustion engine body, gas-fired heat-conducting oil boiler, diesel combustion engine, is usually burned by seamless steel tube plate array fuel gas, inflated in the burner, generating high-temperature flame and flue gas flow between the heating surface, organic The heat carrier tube is designed with a regular flow rate, and the heat generated by the fuel is transferred to the wall of the organic heat carrier to make its temperature and heat output outside the furnace. Second, there is an energy-saving heat exchanger installed at the tail of the gas-fired heat-conducting oil boiler diesel burner. In order to improve the energy conversion efficiency of the boiler-diesel burner system and meet the requirements of safety, energy saving and environmental protection, it is necessary to install an energy-saving heat exchanger. Energy-saving heat exchangers include waste heat steam furnace, air preheater, and economizer. Choose by the user. It is necessary to select a matching burner to change the flue gas flow resistance caused by the installation of an energy-saving heat exchanger at the rear. 3. The burner of the gas stove, gas heat conduction oil boiler, diesel burner is a device for organizing combustion, and a mechatronic product. From the control form: sliding two-level and proportional adjustment; from the structure of the form: integral and split. Split burner; in order to break through the performance limitations of the all-in-one machine, for example, a larger output fan does not require an integrated construction, allowing high-temperature combustion air, and the power source noise source can be transferred to noise reduction and isolation areas. Fourth, high temperature circulating pump, gas heat conduction oil boiler diesel combustion engine Circulation pump is the driving force of the oil heat circulation flow, it must match the rated flow and gas heat conduction oil boiler diesel combustion engine, the flow rate of the circulating pump furnace is matched by Strict design calculations and reasoning should generally not be changed in order to determine. If there are specific reasons to change, the feasibility of matching the heating furnace and circulating pump must be determined according to the specific circumstances. The requirements for traffic are to ensure organic heat. The flow rate of the carrier furnace tube heating furnace can meet the design requirements, ensuring the long-term safety of the organic heat carrier furnace and the heating furnace. When the heating system of the gas-fired heat-conducting oil boiler diesel combustion engine is operating at high temperatures, the circulating pump may malfunction and stop running to avoid the reduction and stop of hot carriers, which will cause the heat carrier to overheat. Deterioration of coking and damage to the furnace. Therefore, in the general heating system, the circulating pump of the gas-fired heat-conducting oil boiler diesel combustion engine should be equipped with two sets, one for operation and one for standby. Once the circulating pump fails, it can immediately switch to standby pump operation. Both pumps should be of the same model and should be kept in good condition. 5. The impurities in the organic heat carrier heating pipeline system of the oil filter for the gas heat conduction oil boiler diesel combustion engine, the normal operation of the system is not good, especially when some solid impurities are sucked into the circulating pump, they will be absorbed by the high-speed pump rotor blades Therefore, the oil filter in front of the online heat carrier circulating pump must be installed to filter out the mechanical impurities and suspended carbon materials in the system and the polymer in the heat transfer oil through the filter screen to protect the function of the hot oil circulating pump . 6. Gas-fired heat transfer oil boiler, diesel burner, oil-gas separator, oil-gas separator. It is a cylindrical pressure vessel. The organic heat carrier rotates at a high speed in the cylinder by the tangent to the circumference. Due to the centrifugal separation, the organic heat carrier fluid Some gas and water vapor are mixed, separated and upward, discharged from the top surface to the expansion tank tube, discharged from the bottom of the tube after the organic heat carrier is discharged, and continue to circulate in the heating system. The gas discharged from the oil and gas separator contains air, water vapor and some volatile components mixed with the organic heat carrier (ie, heat transfer oil). In the heating process of the heating system, these gases must be removed, otherwise it will hinder the normal and stable heating of the heating system. 7. The function of the expansion water tank (high water tank) of the gas heat transfer oil boiler diesel burner expansion water tank is mainly used to compensate for the volume change of the heat carrier due to temperature changes, stabilize the pressure head of the heat carrier, and help the system dehydrate and discharge steam. During normal operation, a high liquid level should be maintained. When there is a sudden power failure or the hot oil circulation pump fails and the furnace needs to be stopped urgently, the cold oil replacement valve can be opened. At this time, the cold oil in the high tank uses its potential energy to flow through the furnace tube to press the hot oil in the furnace into the oil storage tank to prevent the heat transfer oil in the furnace tube from exceeding the temperature. 8. The function of the oil storage tank of the gas-fired heat transfer oil boiler and diesel combustion engine is mainly used to store the heat transfer oil discharged from the high tank, the furnace body and the system, which is convenient for the debugging and maintenance of the gas organic heat carrier furnace and auxiliary equipment. It should be at a low level during normal work, ready to accept external heat transfer oil. The exhaust port (breathing port) should be connected to the safe area, and no valve should be installed (except for the nitrogen protection system). 9. Fuel pump for gas-fired heat transfer oil boiler diesel combustion engine 2CY gear oil pump is used to supply or extract heat transfer oil to the system so that the operator can adjust the heat transfer oil in the system. The direction of the arrow on the pump body should be the rotation direction of the main shaft and the flow direction of the medium. The heat carrier furnace control system integrates local instruments, centralized control instruments and strong current control. It is the center and key of heating furnace control, the temperature, liquid level, pressure difference or flow rate that the heating furnace detects and controls, as well as the automatically adjusted heat load. Commonly used instruments mainly include platinum thermal resistance, electric contact pressure gauge, bimetallic thermometer, digital temperature controller, digital pressure controller, pressure gauge, liquid level controller, burner controller, etc. The power supply is usually ~380 / 220vac ±10%, 50Hz±5%, working environment temperature≤50℃, relative humidity 85% is suitable. In order to ensure long-term safe and reliable operation of gas stoves, the following interlock protections (alarms) are usually set: high fuel tank and low liquid level, overheating of hot oil at the outlet of the gas stove, high and low pressures (low flow) at the water inlet and outlet, and shutdown of the circulating pump. 1. Power control The power control part mainly controls the start and stop of the circulating pump, jet pump and burner fan, so that the circulating pump runs, the pressure (or flow), the high oil tank level, the heat transfer oil temperature and the burner are linked to ensure the safety of the heating furnace run. 2. Instrument display control The instrument display control is pided into local display and centralized instrument control. Normally, the burner load is controlled by the outlet oil temperature. Adjust the oil temperature and control the switch of the burner; the user knows the output of the furnace and the heat of the equipment through the inlet and outlet oil temperature. Low heat conduction oil entering the furnace pressure display and alarm, high pressure display and alarm or flow display and alarm; low liquid level alarm of the expansion tank. Ensure that there is enough heat transfer oil to participate in the circulation, and use the temperature signal to control the burner to achieve the function of automatic load adjustment. !
