    Steam generator (railroad) - Wikipedia

    A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars.The output of a railroad steam generator is low pressure, saturated steam that is passed through a system of pipes and conduits throughout the length of the train. Steam generators were developed when diesel locomotives started to replace steam locomotives on

    Mar 04, 2020 · When the water is boiled in steam boiler, the steam is produced which is then super-heated after which it is passed to the turbines. Then the exhausted steam from turbine blades, is passed through steam condenser of turbine in which the steam is condensed and this condensed water then is pre warmed first in feed water heater then in it before re-feeding in boiler.

    Economizer - Wikipedia

    Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design.In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers.. Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant.
