Flue-gas stack - Wikipedia

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

How Power Plant Boiler Works? How Combustion System in

Jan 28, 2009 · Flue gas system. Coal burns in the furnace giving out heat and forming flue gases. Induced Draft Fan. The hot flue gases from the furnace is drawn out by the Induced draft fan. The gases passes through the various heating surfaces of the boiler, the Electrostatic Precipitator and discharges to the atmosphere at the top of the stack.

Coal fired boiler - Guideline for energy efficient

Higher oxygen level means excess air, Excess air in flue gas takes away heat along with flue gases. Improper air supply: Carbon monoxide generation in flue gas indicated improper combustion of fuel and it must be avoided. Fuel used in the boiler should be combusted completely to get complete heat of fuel.

Air Pollution Control Technology Fact Sheet

A heat recovery boiler, an evaporative cooler or a heat exchanger is typically used to cool the gas. Nonetheless, it is the preferred process for coal-fired electric utility power plants burning coal due to the low cost of limestone and SO 2 control efficiencies from 90% up to 98% (Schnelle, 2002). As t he hot flue gas mixes with the

Coal fired boiler - Guideline for energy efficient

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.

Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash). The distribution of ash between the bottom ash and fly ash fractions directly affects the PM emission rate and depends on the boiler firing method and furnace type (wet or dry bottom). Boiler load also affects
