The boiler is to heat thermal oil which as a heat conducting media provides ultra high temperature to working liquid .

Vegetable oil deodorizer needs to work under high temperature environment which normal pressure steam boiler cannot reach. Thermal oil (heat conducting oil) as a cost-effective solution is suitable for the heating task.  This type boiler burns coal to heat type320 thermal oil which will heat thermal oil to 280 degree through stainless steel heat exchanger.
