A thermal oil boiler fires through a helical coil and generates energy from the hot products of combustion. This, by heating the coil through radiation and convection.
The coil heats the thermal oil or fluid that is pumped through the thermal oil boiler. The thermal oil heats coils in various types of heat users. Unlike a water or steam boiler, this heating process does not heavily pressurize the system.
It is widely used in industry, food processing, printing and dyeing, rubber and building materials industries.
