working principle
energy conversion
- In the power plant, a primary energy of fuel (coal / oil / gas) is converted into electricity (secondary energy), dg following stages:
- First, dlm chemical energy of fuel is converted into heat energy in the boiler fuel, the combustion process dlm
- Second, the heat energy over the next they will be converted into energy in the steam (enthalpy) in the boiler, through a process of heat transfer
- Third, the energy in steam (enthalpy) then converted into mechanical energy / spin in the form of steam turbine
- Finally the mechanical energy is converted from a steam turbine to electrical energy in generator
- Water and steam cycle
- Water is pumped into the boiler
- The fuel is sprayed into the engine with combustion air
- Fuel and combustion air in the room they will be turned on fuel
- Results from the burning of fuel they will alter the chemical energy contained dlm fuel into heat energy
- heat of combustion energy they will be moved to the water in the boiler pipes (as radiation, convection, conduction), SHG water turns to steam temperature and pressure dg certain
- let-in combustion air into the engine to supply the necessary oxygen combustion process dlm
- This air is supplied using a fan dg Press Forced Disappearances and the suction fan
- Gas-burning waste the rest of the reply still had a high temperature then used to:
Raise the temperature of steam at the Super Heater (SH)
Raise the temperature of steam at Reheater (RH)
Raise the temperature of filling water into the boiler at Economiser (Eco)
Raise the temperature of the incoming combustion air to fuel keruang Air Heater (AH)
Then the exhaust gases are channeled into the flue for disposal. But before they were distributed to the chimney, the temperature should be controlled to avoid too low which may result in rapid corrosion rate pd element AH cold side. Besides, to prevent environmental pollution, fly ash (fly ash) reply contained in the exhaust gases have been arrested in the Electrostatic Precipitator (EP)
- Steam from the boiler when the temperature is raised included pd SH High Pressure (HP) Turbine
- Steam from the HP turbine, RH inserted prior to elevated temperature is inserted into the Intermediate Pressure (IP) Turbine
- The steam from IP turbine directly inserted into the Low Pressure (LP) Turbine
- In these turbines in the steam energy / enthalpy is converted into mechanical energy
