Steam Rankine Cycle - an overview | ScienceDirect Topics

Steam Rankine cycle is known as one of the main power-generating cycles, which consists of four key devices, namely a boiler (heat exchanger), a steam turbine, a condenser (heat exchanger), and a pump, as illustrated in Fig. 28.This cycle needs heat input for the boiler either by burning fossil fuels, such as oil, coal, and natural gas, or by obtaining the necessary heat from renewable energy

Operation and maintenance schedule of a steam turbine

A boiler generates steam at the desired pressure and temperature by burning fuel in its furnace. Boilers are used in both fossil-fuel and nuclear-fuel electric generating power stations. A boiler is a complex integration of furnace, super heater, reheater, boiler or evaporator, economizer, and air

Rail transport - Wikipedia

Rail transport (also known as train transport) is a means of transferring passengers and goods on wheeled vehicles running on rails, which are located on tracks.In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run.Tracks usually consist of steel rails, installed on sleepers (ties

Economizer - Wikipedia

The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economiser.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.

Pump Efficiency - an overview | ScienceDirect Topics

Essentially, this is because although feed heating raises the thermal efficiency η L, it leads to a higher value of T S and hence a lower value of the boiler efficiency, η B. The overall lower cycle efficiency (η O) L = η B η L may be expected to change little in the expression for combined cycle efficiency …
