Coal dust burner for coal burning furnace used in steel factory

Coal dust burner for coal burning furnace used in steel factory

Coal dust burner is widely used for industrial boiler (such as heating, annealing, tempering), heating boiler, conduction oil boiler (drying, vaporing) and other kinds boilers. It can be used instead of fuel oil, gas, and electrical heat energy equipment, which can save 50% energy.

Coal dust burner structure:

Coal dust burner is mainly composed of pulverized coal machine, host of combustion machine(including combustion chamber, automatic 

back and forth motion system, automatic rotation system, the combustion air supply

 system) control system, ignition system, the crater and others.

 Coal dust burner working principle:

In the worksite, a coal burner works with the coal pulverizer and coal hopper usually. The coal in the hopper is conveyed to the coal pulverizer by screw conveyor. The coal pulverizer will crush the coal into pulverized coal. In the coal burner, the pulverized coal mixes with air (High-speed air flow is generated by the draft fan on the coal burner), and is ignited by the oil burning igniter.

Coal dust burner characteristics:

Thick lining panel: Coal burner , the inner shell lining is with thick chrome steel plates. So it is very durable.

High wear-resistant hammer for crushing.

Small particle size: after crushed,the particle size is smaller, when burning it will be more sufficiently and more environmental(less smoke). The particle size is about 160-200 mesh.

High production capacity.  Coal burner is with reasonable design, 10% higher than similar products in production.

Combustion. Our machine has double oxygen input, it can improve efficiency and burn sufficiently.

Rapid deceleration integration: reduction gear and spindle are designed in same group, to save electricity.

 Coal dust burner application:

Pulverized coal burners have a wide range of uses in industrial production and daily life, such as providing heat for

 boilers, hot mix asphalt plant, cement kiln, metal furnace, annealing, quenching furnace, precision casting shell 

burning furnace, melting furnace, forging furnace and other heating furnace or kiln.

Mark of coal: bituminous coal;
Gross calorific value: ≥5000kcal/kg (≥ 20000kJ/kg);
Net calorific value: ≥4200kcal/kg;
Volatile matter: ≥25%;
Ash Content: ≤10%;
Total moisture: ≤35%;
