Rotary dryer heating equipment of coal pulverizer

Rotary dryer heating equipment of coal pulverizer 

Coal pulverizer 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 pulverizer characteristics:

Thick lining panel: coal pulverizer, 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 pulverizer 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 pulverizer technical parameter:

Coal burner introduction:
Coal burner (or pulverized coal burner) is a mechanical device that burns pulverized coal into a flame in a controlled manner. Coal 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 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 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%;
Inherent moisture: ≤14%;
Total sulphur: ≤1%;
Particle size: ≤20mm.
Note: These indexes are the lowest requirements for the coal, the better coal will be better at practice.

Full set equipment include:coal pulverizer, coal burner, electrical control cabinet, ignition system and rubber pipe,etc.
