#Steam power plant generator#

After passing through the high pressure turbine, the steam is returned to the steam generator for reheating (in a reheater) after which it is sent to the low pressure turbine. Primary steam is supplied to the high pressure turbine. Reheater The function of reheater is similar to the superheater in that it serves to elevate the steam temperature. Superheated steam arrives back at the superheated steam chamber of the superheater header and is fed into the steam pipe to the cylinders. Steam from the main steam pipe arrives at the saturated steam chamber of the superheater header and is fed into the superheater elements.

The superheater consists of a superheater header and superheater elements.

Wet steam from boiler is heated up in Superheater-Prime mover-HP turbine-Superheater-LP turbine-condenser -hot well.

In Boiler the water circulates due to difference in density of water in the lower temp.

Ash after combustion collects at the back of the boiler and is removed to the ash storage yard.Īir is taken in from the atmosphere through the action of a forced or induced draught fan and passes on to the furnace through the air preheater, where it has been preheated by the flue gases which pass to the chimney via preheater.Ĭondensate leaving the condenser is first heated in a closed feed water heater through extracted steam from the lowest pressure extraction point of turbine. Stage 3: In the third stage, rotation of the turbine rotates the generator rotor to produce electricity based of Faraday’s Principle of electromagnetic induction.Ĭoal arrives at the storage yard and after necessary handling passes to the furnace through fuel feeding device. The steam is then condensed to water and pumped back into the boiler to repeat the cycle. The impulse and the thrust created rotates the turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine. In modern power plant, boilers produce steam at a high pressure and temperature. The heat from combustion of the coal boils water in the boiler to produce steam. Stage 2: The second stage is the thermodynamic process. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Coal is burnt in the boiler furnace to produce heat. Stage 1: The first conversion of energy takes place in the boiler. The conversion from coal to electricity takes place in three stages. How coal power plants produce electricity To produce Electric power from Fossil Fuel and to Produce steam for Industrial Processes like textile, food manufacturers, paper mills etc This is done by raising the steam in the boilers, expanding it through the turbines and coupling the turbines to the generators which converts mechanical energy to electrical energy. In this Article we Covered all Possible aspect to discuss what is Steam Power Plant And How it Work.Ī steam power plant converts the chemical energy of the fossil fuel (Coal) into mechanical energy/electrical energy. The article is based on Steam Power Plant.
