The working principle of the heat transfer oil furnace is as follows: coal, heavy oil, light oil, natural gas or flammable liquid as fuel, and heat transfer oil as heat carrier. The circulating oil pump is used to force the liquid phase to circulate, and the heat energy is transferred to the heating equipment, and then returned to the reheated DC type special industrial furnace.
Shandong Longxing Chemical Machinery Group is committed to the research and innovation of thermal oil furnaces. At present, the company's heat conduction oil furnace has vertical hand-fired biomass heat transfer oil furnace, horizontal chain coal-fired heat transfer oil furnace, vertical fuel heat transfer oil furnace, horizontal fuel heat transfer oil furnace, vertical gas heat transfer oil furnace, horizontal The gas heat conduction oil furnace and the electric heating heat conduction oil furnace can fully meet the fuel requirements and plant requirements of different customers.
Thermal oil furnace operating procedures:
First, the inspection before the start
1. Whether the heating furnace and its surroundings are clean and free of debris, check whether the furnace body, burner, controller, fire hole, chimney, etc. are normal;
2. Reverse the process equipment and process, check whether the oil level of the expansion tank is above the 1/4-1/2 liquid level, and whether the thermometer, pressure gauge, etc. are normal;
3. Turn on the power supply of the heating furnace control cabinet, check whether the voltage is normal, check whether the indicator light and each display instrument are normal;
4. Adjust the gas main pressure reducing valve and the secondary pressure reducing valve so that the pressure is controlled to 0.005 MPa.
Second, start
1. Start the heat-conducting oil circulation pump (save one for one, refer to the pump operation procedure), and start the pump for about 0.5 hour after normal circulation to make the pressure stable;
2. Press the burner start button to observe whether the furnace flame is burning normally. If it does not ignite, the burner should be started again after troubleshooting.
Third, stop operation
1. Normally shut down the furnace 1 gradually reduce the temperature, turn off the burner, stop the combustion; 2 wait for the temperature of the hot oil to drop below 70 °C, stop the operation of the hot oil circulation pump (refer to the pump operation rules); 3 turn off the total power supply, do a good job Handover record.
2. Emergency shutdown, if the furnace is emergency shut down due to emergency, the burner should be quickly shut down, and the burner should be removed along the hinge of the burner to form a natural ventilation between the furnace and the chimney, and the heat storage in the furnace Dissipate so that the heat transfer oil cools naturally to prevent overheating.
