MP1000 Coal dust burner for cement dryer kiln

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 dust burner (or pulverized coal burner) is a mechanical device that burns pulverized coal into a flame in a controlled manner.

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 technical parameter:

Pulverized coal machine structure and working principle:
Pulverized coal machine is consist of feeder, grinding chamber, fan chamber and separator.
Grinding chamber is consist of crushing body, main shaft, coal hammer and lining board.
Fan chamber, installed fixed fan on shaft, spraying coal powder to burner.
At the bottom of separator, connect with machine body, at the top, coal powder conveyor connect with pipe,
In the cutting edge of separator welded with big size coal powder backflow pipe connect with material entrance, big size coal back to grinding chamber for grinding again.

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.

There are mainly two ways to ignite the Coal dust burner. Manual way and automatic way, no matter which way it adopts, the coal burner often needs fuel(oil, gas, etc) as the combustion medium. The difference is that the high-energy ignition devices which generate sparks replace people's hands.

Coal dust burner application:

Coal dust burner 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;
