Depending on speed pulverizers are classified as lowspeed, mediumspeed, and highspeed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuelfiring systems: bin system and directfiring system. Coal feeders are either the volumetric or gravimetric type.
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 (Highspeed air flow is generated by the draft fan on the coal burner), and is ignited by the oil burning igniter.
Bowl Mill has long been recognized as the most advantageous design of the coal pulverisers and include low initial cost, low maintenance cost, removal of tramp iron, low power consumption, easy maintenance, wide range output, quiet operation. The basic features of Bowl Mill (Puveriser) supplied by BHEL are:
Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. For more information : .
For example, a pulverizer mill is used to pulverize coal for combustion in the Attrition Mill Both types of mill include liners that protect the cylindrical structure of the mill from wear . Create a book · Download as PDF · Printable version. impact type coal pulverizers
Stoker Fired Boiler are classified according to the method of feeding fuel to the furnace and by the type of grate. The main types of stokers are: Chaingrate or travellinggrate stoker Spreader stoker boiler Travelling Grate or chain grate Stoker Boiler In Travelling Grate boiler coal .
LargeOil Burner ABB. ME 416/516. Coal/Solid Fuel Firing. There are a considerable number of ways to feed coal in use, including, handfired boilers, chain or traveling grate stokers, vibrating grate stokers, underfeed stokers, spreader stoker, pulverized coal boilers, cyclone boilers and fluidized bed boilers.

Types The nature of coal is such that the higher the carbon content, the more cleanly and brilliantly the coal burns. Thus "peat", which is the state of the decomposing plants before being compressed, is a weak, impure substance. The other states of coal from lowest carbon content to highest are lignite, bituminous coal, and anthracite coal.
4 Mercury Types From Power Plants CCTR Indiana Center for Coal Technology Research • 40% of Hg from power plants is Oxidized Hg 60% of Hg from power plants is Elemental Hg • Most of the Oxidized Hg and all of the Elemental Hg is carried away by the wind • Oxidized Hg is small amount of the oxidized Hg ends up in water
Uses of coal. Coal has many important uses worldwide. The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal also known as thermal coal is mainly used in power generation.
