Thermal oil boilers, also known as organic heat carrier boilers, are a new type of thermal energy equipment that uses thermal oil (organic heat carrier) as the heat transfer medium. Unlike traditional boilers that use water/steam as the medium, it heats the heat transfer oil, then uses an oil pump to force circulation, delivering heat energy to the heat-using equipment, and then returns to the boiler for reheating, forming a closed-loop system.
Working Principle:
Heating process: Fuel (such as natural gas, diesel, biomass, etc.) is burned in the combustion system (burner), and the high-temperature flue gas generated transfers heat to the heat transfer oil flowing in the tubes through the heating surface of the boiler (coil or furnace tube).
Circulating heat transfer: High-temperature heat transfer oil, driven by the circulating oil pump, flows out from the boiler outlet and is transported to one or more heat-consuming equipment (such as reactors, presses, dryers, etc.) through high-temperature oil pipes.
Heat release process: In heat-using equipment, high-temperature heat transfer oil releases heat and its temperature drops.
Return reheating: The cooled heat transfer oil passes through the return oil pipe and is drawn back to the boiler by the circulating oil pump for reheating, starting the next cycle
