Air pre heater is used to transfer heat from the flue gases to the air before it passes into the furnace for combustion. It is placed between the economizer and chimney. The overall efficiency of the plant may be increased by 10 per cent by the use of air preheater.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

bunker or coal yard. In the case of emergency the coal is fetch from coal yard. Coal feeder control the quantity of coal from coal bunker and send it to the ball mill or roll mill for pulverization process. Where coal crushed to the fine powder and mixed with preheated air come through the air from preheater.

· This test assesses a dust's sensitivity to heat. The minimum autoignition temperature (MAIT) is the lowest temperature at which a dust cloud will autoignite when exposed to hot air. Minimum ignition energy (MIE) This test determines the smallest amount of ignition energy required to ignite a dust cloud. Dust layer ignition temperature (MIT)

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Most often, "Clean Air" testing refers to measurement of primary air in a coal piping system when the coal flow is off. Since the Clean Air Pitot Probe meets EPA Method 2 specifiions, it can also be used to measure any air or flue gas flows, including secondary air, boiler outlet, air heater inlet/outlet, electrostatic precipitator inlet/outlet, or stack exhaust.

· The coal, which is pulverized in the mills, is transported and distributed by the primary gas through the millducts to the interior of the furnace. This is done with a double function: dry and enter the coal by different levels for optimizing the combustion in the sense that a complete combustion occurs with homogeneous heat fluxes to the walls.

· Soot is a major cause of global warming. While carbon pollution gets most of the headlines, soot is a very important contributor to the problems caused by climate change. Climate scientists refer to black carbon—the main component of soot—as a "climate forcer.". Soot particles absorb radiation from the sun and can hasten the melting of ...
