Ascoalis dried and its HHV increases, lesscoalis needed for desiredpoweroutput, resulting in lowerflue gasflow rate and heat capacity, and lower convection pass heat transfer.
Flue Gasas Path In Coal Power Plant A typical coalfired power plant with an electrical output of 500 mw requires about 50 kg s1 of coal and about 550 kg s1 of air to produce about 600 kg s1 ofexhaust gasthis translated into volumetric air andgasvolume flow rates at the inlet and outlet gives about 500 m3 s1 and 675 m3 s1 respectively

Typical flue gases from natural gas-fired power plants maycontain 8-10% CO 2,18-20% H 2O,2-3% O 2, and67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2. The typical furnace outlet temperature of flue gases is usually around 1200 °C which will decreases gradually along the pathway of heat transfer, while the temperature of the flue …

Jan 24, 2016· Flue Gas Flow. After burning of coal it is converted into Fly Ash and Bottom Ash. This Fly Ash contain huge amount of heat energy. So we utilise that energy to increase the efficiency of boiler. In flue gas path, weplace boiler auxiliaries which increase the efficiency of boiler by absorbing the heat content in the Flue Gas.
