Complaint
Shandong Longxing Group is a large group manufacturer of heat transfer oil heat carriers and hot water and steam heating boiler equipment. For the past 30 years, our company has been committed to the development, design, and manufacture of a series of oil-fired and gas-fired organic heat carrier furnaces/heat transfer oil furnaces, electric heating heat transfer oil furnaces, oil-fired and gas-fired steam boilers, oil-fired and gas-fired hot water boilers and steam generators, waste heat exchangers and other equipment.
Electric heating transfer oil boiler is to directly insert the electric heater into the organic carrier (heat transfer oil) for direct heating, use the circulating pump to force the heat transfer oil to carry out liquid phase circulation, and transfer the heat to one or more heat consuming equipment. After being unloaded by the heat consuming equipment, it will pass through the circulating pump again, return to the heater, and then absorb the heat, and transfer it to the heat consuming equipment, so as to realize the continuous transfer of heat and raise the temperature of the heated object to meet the heating process requirements.
Generally, the heat transfer oil heating boiler is composed of the main machine (heating body, high-temperature oil pump and filter), oil tank, control cabinet, pipeline, etc. as a complete set of equipment and the heating equipment to form a heating system with forced liquid circulation.
The Thermal Oil Heater with stable performance and reliable quality is an efficient heating equipment, which uses electricity as a heat source and heat transfer oil as a heat carrier, passing thermal energy to the heat users through the forced circulation of the hot oil pump, and returning to the Heater for reheating and recirculation.
Electric heating organic heat carrier heat transfer oil boiler is a new type of environmental friendly heat energy conversion equipment. The heat transfer oil heater is controlled by a digital temperature controller and has the functions of over-temperature alarm, low oil level alarm and over-pressure alarm. It is an efficient and energy-saving heating equipment in the industries of chemical industry, petroleum, machinery, printing and dyeing, food, shipping, textile, film, etc.
1.Low operating pressure: the liquid phase transports heat energy and can obtain a higher operating temperature at a lower operating pressure. The saturated steam pressure of the heat carrier is 70~80 times lower than that of water, and the general heating operating pressure is ≤ 0.3MPa.
2.High heating temperature: the heating temperature of heat transfer oil heating furnace can reach 280 ºC; Automatic control of heating temperature, high sensitivity and stable heating.
3.Safe and reliable: We specialize in the research and development of organic heat carrier furnaces, with perfect operation control and safety monitoring devices, which are easy to operate, safe and reliable.
4.Environment-friendly design: the organic heat carrier boiler is equipped with a new electric heating system, which replaces coal with electricity, saves investment, and is environmentally friendly and pollution-free. At the same time, the electric heating of the organic heat carrier heat transfer oil boiler heats up quickly, with high thermal efficiency, efficiency and economy!
A. Pre-start inspection
1. Check whether the heating furnace and its surroundings are clean and free of sundries, and whether the furnace body, burner, controller, fire hole, flue (chimney), etc. are normal
2. Reverse the process equipment and flow, check whether the oil level in the expansion tank is above 1/4 - 1/2 level, and whether the thermometer and pressure gauge are normal
3. Connect the power supply of the heating furnace control cabinet, check whether the voltage is normal, and check whether the indicator light and all display instruments are normal
4. Adjust the main pressure reducing valve and secondary pressure reducing valve of the gas to control the pressure to 0.005 MPa.
B. Start
1. Start the heat transfer oil circulating pump (one for operation and one for standby, refer to the operating instructions of the water pump), and circulate normally for about 0.5 hour after starting the pump to stabilize the pressure;
2. Press the burner start button to observe whether the furnace flame is burning normally. If not, start the burner again after troubleshooting.
C. Shutdown operation
1. Normal shutdown
a. Gradually reduce the temperature, shut down the burner and stop burning;
b. When the temperature of hot oil drops below 70 ºC, stop the operation of hot oil circulating pump (refer to the operating instructions of water pump);
c. Turn off the main power supply and make shift handover records.
2. Emergency shutdown
If the boiler is shut down in an emergency, the burner shall be shut down quickly, and the burner shall be moved away along the hinge axis of the burner to form a natural ventilation state between the furnace and the chimney, so as to dissipate the heat storage in the furnace, so that the heat transfer oil can be cooled naturally and prevent overheating.
D. Attention
During patrol inspection, pay attention to check whether there is leakage around the heat transfer oil furnace. There should be enough oil fire fighting equipment and electrical fire fighting equipment nearby. Water is not allowed to be used as fire extinguishing agent.
The whole complete set of the thermal oil heater consists of the heating system, the circulation system, the electronic control system, and the expansion system.
1. The heating system: the main component is the electric heating oil Heater, it consists of the heating pipes, inlet and outlet oil pipes, frame, diversion devices, and protection cover.
2. The circulation system: the filter, high-temperature oil pump, oil Heater pipe, valves, and heat-demanding equipment constitute a closed loop.
3. The expansion system: It mainly consists of the housing body, expansion pipe, overflow pipe, exhaust pipe, sewage outlet pipe, plate level gauge, and float level controller. Its role is to accept the expansion oil, compensate the circulatory system, supercharge, exhaust, alarm oil level, and spill oil. The volume of the expansion slot can be configured according to the user's requirements.
4. The electronic control system: the electrical apparatus control cabinet is the main operation control part of the organic heat carrier Heater, and it plays a part in starting/stopping the pump, heating temperature, controlling temperature, displaying temperature, and liquid level alarm.
