Steam Turbine Power Plants Engaged in

Steam Cycle. A steam cycle power plant is operated using the Rankine cycle. Water enters a boiler where it is heated to create steam. The steam is then sent through a steam turbine that rotates the shaft of a generator to create electricity. The steam exits the turbine into a condenser, which converts the steam back into saturated water.

Steam oxidation in steam boiler and turbine

Steam from the separator is fed into the primary and secondary superheaters. From there the steam goes to the high-pressure turbine, then to the reheater, the intermediate-pressure turbine, the low-pressure turbine, and then to the condenser. From the condenser, water goes back to the boiler feed pump to then repeat the cycle.

What is the function of economizer in boiler?

Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. The feed water is never open to the atmosphere. This cycle is known as a closed system or Rankine cycle.
