Flue Gases In Steam Power Plant. Water is required in a thermal power plant inside a boiler to produce steam. The hot air is supplied to the furnace of the bolier.
Thermal Power Plant |Steam Power Plant - Layout And Working from coalhandlingplants.com
Instead of using steam extracted from the steam turbine cycle for the combustion air preheat, combustion air is preheated by the heat recovered from the flue gas stream. This requires flue gas to be cooled from 310f to 258.9f in the fgc. Air and flue gas circuit consists of forced draught fan, air pre heater, boiler, furnace, super heater, economiser, dust collector, induced draught fan and chimney.
A 100 Mw Steam Station Uses Coal Of Calorific Value Of 5780 Kcal/Kg.

What consists of air and flue gas circuit? Combustion products of these fuels are called flue gases.
3 Water And Steam Circuit.
• after that it passes through a dust collector. To cool the flue gas to its saturation temperature, 211 klb/hr of water must be evaporated in the fgd. In a thermal power plant ( in case of coal and lignite) steam is generated in the steam generator by heating the water.
The Thermal Efficiency Is About 30% And The Electrical Efficiency Is 93%.
Name the four major circuits in steam power plant. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen derived from the. Feed water and steam circuit;
La Yout Of Steam Power Plant
Air and flue gas circuit consists of forced draught fan, air pre heater, boiler, furnace, super heater, economiser, dust collector, induced draught fan and chimney. Flue gases in a thermal power plant before being released through the chimney. • the flue gases from the furnace pass over the boiler tubes and super heater tubes.
This Requires Flue Gas To Be Cooled From 310F To 258.9F In The Fgc.
Flue gas heat recovery in power plants, part i as moisture condenses out of the flue gas steam, the flow rate of flue gas decreases, causing a slight decrease in the amount of sensible heat in flue gas (figure 8). Combustion products depends on the constituent of the fuel and other reactants. Air and flue gas circuit:
