Fuel/Gas Thermal Oil Boiler is a assembled forced circulation vertical fuel (gas) boiler. The boiler body has a compact heating surface structure, consisting of inner and outer densely packed discs. The inner disc tubes form a radiant heating surface, while the outer surface of the outer disc tubes forms a convective heating surface. The boiler is composed of an upper body and a lower combustion chamber, assembled on-site. After the combustion is fully completed within the combustion chamber, the high-temperature flue gas absorbs most of the heat through the radiant heating surface, then enters the convective heating surface for heat exchange. After leaving the boiler, the air required for combustion is heated in the air preheater, and then the flue gas is sent to the chimney and released into the atmosphere by the induced draft fan through the dust collector. Precautions for using Fuel/Gas Thermal Oil Boiler: 1. Operate strictly according to the heating curve. 2. Do not use when the pressure difference is unstable. 3. Stop the thermal oil circulation pump only when the oil temperature drops below 80°C during shutdown. 4. Ensure good thermal oil circulation during high-temperature operation. 5. Maintain a high liquid level of thermal oil in the high-level tank during normal operation, and a low liquid level in the storage tank. 6. The outlet temperature of the oil must not exceed the allowable working temperature of the thermal oil. 7. Do not use water to flush the furnace during emergency shutdown. 8. Do not mix different types of thermal oil. 9. The vent of the storage tank should be connected to a safe area. 10. The initial heating rate must be carried out according to the heating curve. 11. Start the induced draft fan before the blower, and stop the blower before stopping the induced draft fan. 12. The boiler room should be equipped with electrical and oil fire fighting equipment.
