Explain about functions of thermal power plant pa fan. PA Fan is primary air fan which is used in power plant to push the coal from mill to furnace and to maintain the powdered coal always in dry state.
Coal System Coal received from the mines is stored in the coal yard adjacent to the power plant. It is then conveyed on a daily basis to the boiler and stored in a 'Coal Silo'. 'Coal feeders' continuously feed the required amount of coal to the 'Coal Pulverisers'. Coal Pulverisers grind the coal to a very fine powder to make it burn easily.

A large part of human CO2 emissions comes from fossil fueled thermal power plants; efforts to reduce these outputs are various and widespread. In a coal based power plant coal is transported from coal mines to the power plant by railway in wagons or in a merrygoround system. Coal is unloaded from the wagons to a moving underground conveyor belt.
CONCLUSIONS A simulation and experimental study of the flue gas path in a coalfired power plant was presented. The simulation model was written in the objectoriented language Modelica. The model is based on firstprinciple equations, and most of it is made of component models already present in the ThermoPower library.

400MW case uses a fan arrangement of 1 PA/1 FD/1 ID, and the 600and 900MW cases use a 2 PA/2 FD/2 ID fan arrangement (axial ID fans for 900MW case). Fan power requirements are based on the fan arrangements, the estimated gas flows for each specific coal case, and the specific environmental equipment for each case. ENVIRONMENTAL CONTROLS
The main function of the PA FAN (Primary Air Fan) is to convey the fuel mainly coal to the furnace with Air Pressure created by the Fan. The pressure normally maintained by this Fan is around 1000mmWC to overcome the pressure drop in Pulverisers and Coal Pipe. ... Normally one independent thermal power plant comprises of 2PA Fans.

A typical coalfired power plant with an electrical output of 500 MW requires about 50 kg s–1 of coal and about 550 kg s–1 of air to produce about 600 kg s–1 of exhaust gas. This, translated into volumetric air and gas volume flow rates at the inlet and outlet, gives about 500 m3 s–1 and 675 m3 s–1 respectively.
Emissions from a thermal power plant can be characterized generally (and in relative amounts of mass emitted) as: CO2 Carbon Dioxide. Formed when you burn anything contai . ning carbon including coal, oil, natural gas, wood, biomass. CO2 is the largest emitted greenhouse gas from a thermal power plant, and is the most difficult to control.
