Boilers are defined as “ Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.
Boiler slag is a coarse, granular, incombustible by-product of coal combustion and is thus classified as a coal combustion byproduct. It is angular, dense , and very hard. Boiler slag is only produced in a wet-bottom boiler, as this boiler has a special design that keeps bottom ash in a molten state until it is removed.
The coal combustion takes place in this suspended condition. This is the Fluidized bed. Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources.
Boiler Efficiency. Boiler efficiency includes the calculation of sensible heat losses (in boiler flue gases and ash), which are dependent on coal composition, excess air levels and temperatures at boiler inlet and airheater outlet.
Boiler Slag. Boiler slag is the molten bottom ash collected at the base of slag tap and cyclone type furnaces that is quenched with water. When the molten slag comes in contact with the quenching water, it fractures, crystallizes, and forms pellets.
Bituminous coal is commonly used in power plant boilers for generation of electric power. Bituminous coal has a higher boiler heating value than either sub-bituminous or lignite, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest and Appalachian regions. Plant chemists conduct analyses of the coal as it is received.

The most common stove for heating in the industrial world for almost a century and a half was the coal stove that burned coal. Coal stoves came in all sizes and shapes and different operating principles. Coal burns at a much higher temperature than wood, and coal stoves must be constructed to resist the high heat levels.
Jul 17, 2017 · They occur in the high-temperature furnace area of the boiler. Clinkers form as a result of interaction among coal quality, boiler design and boiler operation. Coal boilers draw their combustion air from the bottom, up through the combustion grate. Lots of large clinkers on the combustion grate can hinder air passage, increase operation and maintenance costs and even force shutdowns of the boiler for cleaning out the clinkers.
Major solid fuels used for burning in a boiler include coal and wood. They were the only fuel sources available for use in boiler systems prior to the emergence of heating fuel oil. These are the cheapest means of boiler fuels which are getting exhausted day by day due to uncontrolled use.
A pulverized coal–fueled boiler is designed with a large furnace cavity that can tolerate liquid phase slag on the waterwalls. The furnace exit, however, should be at a low enough temperature that
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
