  • Economizer - Wikipedia

    2021-9-6 · 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.

  • Absorption Refrigeration System - an overview ...

    Carré's absorption refrigeration technique is an important vapor refrigeration technology, because it does not require a vapor compressor. It is based on dissolving the refrigerant vapor (ammonia) in a carrier liquid (water) and pumping this liquid to a high pressure. A liquid can be pumped more efficiently than a vapor can be compressed, so this technique has a decided advantage over vapor ...

  • Steam-electric power station - Wikipedia

    2021-8-31 · The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator.After it passes through the turbine, the steam is condensed in a condenser.The greatest variation in the design of steam-electric power plants is due to the different fuel sources.

  • Feedwater heater - Wikipedia

    2021-8-24 · A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. This reduces plant operating costs and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into ...
