A coal burner (or pulverized coal burner) is a mechanical device that burns pulverized coal (also known as powdered coal or coal dust
Coal dust is a fine-powdered form of coal which is created by the crushing, grinding, or pulverizer, pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it. ...
since it is as fine as face powder in cosmetic makeup) into a flame in a controlled manner.
Coal burners are mainly composed of the pulverized coal machine, the 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.
Mechanism
In the worksite, a coal burner usually works with the coal pulverizer and coal hopper. 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.Ignition
There are mainly two ways to ignite the coal burner. These are manual and automatic, differing in that in automatic systems, a high-energy ignition device generates sparks, replacing people's hands.Use
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.Requirements for coal
* Mark of coal: bituminous coal; * Grosscalorific value
The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it.
The ''calorific value'' is the total energy release ...

* Net calorific value: ≥4200kcal/kg;
* Volatile matter: ≥25%;
* Ash Content: ≤10%;
* Total moisture: ≤35%;
* Inherent moisture: ≤14%;
* Total sulphur: ≤1%;
* Particle size: ≤20mm.
