Schematic diagram of heat metering system of thermal oil furnace
How it works:
The thermal oil furnace is made of heavy oil. Light oil or combustible liquid is the fuel. Thermal oil is the heat carrier. The circulating oil pump is used to force the liquid phase circulation. After the heat energy is delivered to the heating equipment. Then return to the reheated DC special industrial furnace. Widely used in such as petrochemical. Textile. Printing and dyeing. plastic. Rubber. Food processing. Wood processing. Asphalt heating. Carton production. Dehydrate vegetables. Paint. Casting sand mold drying, etc., can also be used for ≤ 350oC baking, evaporation, shaping, melting, drying.
The measuring instrument of the thermal oil furnace is extremely useful
1. Used for combustion safety devices. His role is to convey information in a timely manner about abnormal situations that occur in the operation of the equipment, cut off the fuel, and safely shut down the equipment. The main instruments are: thermal oil outlet temperature alarm, thermal oil inlet and outlet pressure difference detector, flame extinguishing detector, wind pressure detector, fuel pressure detector, gas furnace heat transfer oil pressure detector, fuel shut-off valve, spray media pressure drop detector, etc. 1.

2. Instrument for combustion control. The main ones are: heating furnace outlet heat transfer oil temperature control meter, flash tank pressure control meter, combustion flow control meter, combustion air flow control meter, combustion oil medium pressure difference adjustment meter, and gas phase furnace flash tank liquid level adjustment meter.
3. Instruments used for operation monitoring. The main ones are, heating furnace outlet pressure gauge, thermal oil circulation pump inlet and outlet pressure gauge, burner internal pressure pressure gauge, expansion tank level gauge, soot concentration meter, oxygen concentration meter, etc. The thermal oil furnace has a high degree of automation, rapid start and stop, safe and reliable operation; High thermal efficiency, stable output, and strong load adaptability; Compact structure, small size, small footprint; There are few supporting auxiliary machines, simple and convenient installation, and short installation cycle; The fuel is fully burned, the pollutant emission is low, and the environmental protection index can be achieved. Therefore, it is an ideal high-efficiency, low-consumption, low-pollution green and environmentally friendly product.
Thermal oil furnace product features
1. It can obtain a high operating temperature at low operating pressure and can be used as a high-temperature heat source below 500°C.
2. The heating temperature is stable, the load-temperature adjustment can be carried out accurately, and the adjustable load section can operate stably and has automatic operation control and safety monitoring device.
3. Closed-circuit circulation heating, high heat utilization efficiency, and significant energy-saving effect.
4. The molten salt is solid at room temperature, and must be preheated before starting, and all the molten salt in the system must be returned to the storage tank when stopping, so starting and stopping are more complicated.
