Coal Fired Thermal Oil Boiler

Solid fuel thermal oil boiler | Chain grate thermal oil boiler | horizontal and vertical boiler

Coal fired thermal oil boiler is horizontal grate combustion three-coil structure, wet back. This boilers are fully automatic, stable heating, energy saving and designed to operate on a wide range of solid fuels, like coal, wood, huskd, sawdust and multiple fuel options.

Thermal Capacity: 200-14,000kw/h 200,000-12,000,000Kcal/h
Rated Temperature: 200 ℃ ~ 350 ℃
Styles: horizontal / vertical
Available Fuel: coal, solid fuels, wood chip, bagasse, straw, and other biomass fuel
Applied Industries: textile printing and dyeing, refinery&chemical, plastic and rubber, wood industry, building material, machinery industry, food industry, etc.



YLW thermal oil boiler is a coal fired boiler used in thermal oil heating systems. It is a longitudinally(horizontal) chain grate boiler that can fueled by coal, wood, biomass and other solid waste. The thermal oil is circulated and heated, then transferring heat to the factory's one or more heating devices.

Product Features

● "Three Layers Coil Tubes + 3-Pass Design"
Effectively use the high temperature, smoke stay inside of boiler to heat thermal oil 3 times,  greatly reduce temperature of outlet smoke, improve boiler thermal efficiency, energy saving, reduce fuel cost

● "Oil Covered Fire" endothermic sufficient, heating up fast and evenly;

Smoke transfer room is wet back structure, avoid burning deformation, ensure boiler lifespan

● "Patented Serpentine Tube Design + Soot Blower + Double Inspection Door" Convenient for inspection and scoot blowing, improve heat transfer rate

● Double layer 12cm aluminum silicate insulation cotton, reduce heat loss, boiler surface temperature is not higher than 40 ℃

● 100% safety with 5 Levels Interlock Control. Super oil temperature alarm, Low oil flow alarm, Over exaust temperature

● Equipped protection devices such as circulation oil pumps/thermal oil flow meters to deal with emergencies such as power outages

● Using energy-saving device like economizer/preheater/cyclon/wet scrubber, environmental protection and energy conservation
