Aug 08, 2017 · 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. Thermal oil systems are superior to water boiling systems. A thermal oil boiler is nearly always cheaper to operate and maintain than water boilers. High pressures required to operate water and steam boilers makes them far more hazardous than thermal oil
The formation of sulfur trioxide (SO(3)) in coal-fired utility boilers can have negative effects on boiler performance and operation, such as fouling and corrosion of equipment, efficiency loss in the air preheater (APH), increase in stack opacity, and the formation of PM(2.5). Sulfur trioxide can a …
