The type of equipment to be used for unloading the coal received at the power station depends on how coal is received at the power station. If coal delivered by trucks, there is no need of unloading device as the trucks may dump the coal to the outdoor storage. Coal is …
Boilers
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm (0.001 in). Coal burns in suspension, like the combustion in an oil- or gas-fired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
The Analysis of Coal and Analysis techniques
The proximate analysis indicates the percentage by weight of fixed carbon, volatiles, ash, and moisture content in coal. The amounts of fixed carbon and volatile combustible matter directly contribute to the heating value of coal. The fixed carbon acts as a main heat generator during burning.
Coal – Types, Uses and Formation
On burning coal, coal ash is formed. This coal ash comprises several minerals like calcium and aluminium, which can be reused. About 40% of coal ash produced each year is effectively reused to fill coal mines that are abandoned. Sometimes, coal ash is used as the topmost layer on roads and foundations of high rise buildings.

the grate. The coal is fed into the grate through the fire door and ash formed is collected in the ash-pit located just below the grate and it is removed manually. The furnace and the combustion chamber are connected through a pipe. The back of the combustion chamber is lined with firebricks. The hot gases from the combustion chamber flow through
INTRODUCTION TO BOILER
burning and grate burning. The coal is continually fed into the furnace above a burning bed of coal. The coal fines are burned in suspension; the larger particles fall to the grate, where they are burned in a thin, fast-burning coal bed. This method of firing provides good flexibility to meet
Coal Combustion and Combustion Products
fresh coal on the bed surface is heated rapidly by the hot combustion gas and the radiation from the high-temperature flames and furnace walls. It is advantageous to the ignition of the coal. The burning coal then descends in turn through the reducing region and the oxidization region, becoming ash on the grate, and is finally removed. Figure 1.

Power Generation from Coal - Stanford University
Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climate-damaging carbon dioxide. This book explores how efficiency is measured and reported at coal-fired power plants.
GAS FLARING IN INDUSTRY: AN OVERVIEW
Gas flaring is a combustion device to burn associated, unwanted or excess gases and liquids released during normal or unplanned over-pressuring operation in many industrial processes, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills.
