What are the operating procedures for diesel burners in gas boilers?

The opening of the gas heat conduction oil boiler diesel combustion engine is more complicated than closing. When opening, always pay attention to the temperature control. Operations have a sequence, but they are relatively fixed. Once you master it, there will be no problems. When checking each place for oil leakage, do not directly grasp it and touch it lightly, because the heat dissipation of the gas heat conduction oil boiler diesel burner is very slow, and it takes a whole day to heat up. Dissipated completely, so we should have some sense of self-protection to avoid burns. The cooling operation steps of the gas heat transfer oil boiler diesel burner should first stop heating, then lower the temperature of the gas heat transfer oil boiler diesel burner, stop its flow, and turn off all power when the temperature drops below 50 degrees. Opening the machine room in the machinery manufacturing workshop is the standard for checking whether the operators are qualified. If the operator can skillfully open and close mechanical equipment, it means that he has the quality of a qualified operator. If these two tasks cannot be completed, it means that there are still many areas to be strengthened. In addition to the opening and closing of the heat transfer oil boiler diesel burner, there are no complicated functions during use, and you do not need to keep staring at it. The temperature can be recorded every 1-2 hours, and the oil pan in the gas heat transfer oil can be checked regularly. Is there a backflow? (1) The design of the full oil circulation system of the thermal oil boiler diesel combustion engine should be comfortable. Minimize elbows and valves. Use a circulating pump. To clean the filter in time, you must ensure that the flow rate of the heat transfer oil at high temperatures is not less than 2 m/s. (2) Correctly select the heating furnace (generally, the nominal capacity is 1. Choose 5 times of Ⅲ) to avoid large overload ratio and uneconomic phenomenon. The selection of the heating capacity of the heating furnace is not only related to the safety and service life of the heating furnace, but also affects the service life and production cost of the heat transfer oil. (3) Choose heat transfer oil with good thermal stability, oxidation resistance and coking resistance. When purchasing heat-conducting oil for boilers and diesel burners, be careful not to choose heat-conducting oil with dark odor and color. The service life of heat transfer oil is measured by four indicators: carbon residue, acid value, flash point and viscosity (Table 1). An oil test is conducted every six months to grasp the quality of heat transfer oil in operation. When a problem is found, replace the heat transfer oil in time, and find out the reasons for the deterioration of the heat transfer oil and preventive measures in advance. At the same time, do not strictly mix heat transfer oils of different product numbers. (4) Use the hot oil boiler diesel burner in strict accordance with the operating procedures to avoid rapid fire and temperature rise (the heating rate should be controlled at 10-40℃, h), over-temperature, over-pressure, and emergency stop measures should be taken quickly and decisively. Observe the oil level and oil temperature of the expansion tank at any time. In the case of shortage of oil resources, timely replenishment. Prevent air and moisture from entering the oil circulation system. The high temperature heat transfer oil will accelerate the oxidation rate after directly contacting the air (when the temperature rises by 10°C, the oxidation rate will increase by 2 times), preventing the high temperature oil from directly contacting the air. A better method is to seal the upper space of the expansion tank with nitrogen. The protective gas film layer is formed under unconditional nitrogen sealing conditions. Under normal circumstances, the heat transfer oil temperature of the high water tank shall not exceed 60℃, and the high water tank shall not be directly connected in series in the circulation system. (5) Improve the thermal efficiency of the diesel burner of the hot oil boiler, and timely remove the dust and dirt on the inner wall of the furnace and the wall of the coil to ensure a good heat transfer effect. At the same time, better quality coal should be used as much as possible so that the heat generated by burning coal can be converted into hot oil in a timely and comprehensive manner. (6) When the boiler diesel combustion engine is insulated, the heat transfer oil circulating pump must not be stopped. Do not stop the circulating pump before the furnace temperature drops to the specified range. In the event of a sudden power failure or failure of the circulation system, in addition to ventilation and cooling. Also need to replace the cold heat transfer oil. !
