  • Coal burner - Wikipedia

    OverviewMechanismIgnitionUseRequirements for coalSee alsoExternal links

    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.

    The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of coal according to the boiler demand and the amount of air available for drying and transporting the pulverized coal fuel is controlled by computers. Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizeralong with air heated to
