A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...

The feed water cycle begins with condensate water being pumped out of the condenser after traveling through the steam turbines. The condensate flow rate at full load in a 500 MW plant is about 6,000 US gallons per minute (400 L/s). Diagram of boiler feed water deaerator (with vertical, domed aeration section and horizontal water storage section).
The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.
First use of internal jet pumps (single nozzle, 10 per loop, 20 total). 2 recirculation loops, variable speed recirculation pumps (one pump per loop, each pump had a rated flow of 45,200 US gallons per minute (2.85 m 3 /s)). Improved ECCS spray and flood, improved feedwater spargers.
Schematic diagram of typical coal-fired power plant steam generator highlighting the air preheater (APH) location. An air preheater is any device designed to heat air before another process (for example, combustion in a boiler), with the primary objective of increasing the thermal efficiency of the process.
In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.
The power station was part of TNB's plan to increase power generation capacity to meet Malaysia's rising electricity demand in the early 1990s. The gas turbine plant consists of two units of 110MW General Electric Frame 9E model and three units of Siemens 135MW V94.2 Ratio model. PJPS is a peaking power plant serving the Klang Valley load ...
