  2. Supercritical steam generator - Wikipedia

    en.wikipedia.org/wiki/Supercritical_steam_generator

    The water temperature drops below the critical point as it does work in a high pressure turbine and enters the generator's condenser, resulting in slightly less fuel use. The efficiency of power plants with supercritical steam generators is higher than with subcritical steam because thermodynamic efficiency is directly related to the magnitude ...

    Electric steam boiler on the training ship Golden Bear. An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals ...

    According to the company, the steam engine named Quadrum generates 27% efficiency and runs with 180 °C steam at 8 bar pressure, while a corresponding steam turbine produces just 15% efficiency, requires steam temperature of 240 °C and pressure of 40 bar. The high efficiency comes from a patented crank mechanism, that gives a smooth, pulseless ...

    High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the ...

  6. Steam–electric power station - Wikipedia

    en.wikipedia.org/wiki/Steam–electric_power_station

    Natural gas is frequently combusted in gas turbines as well as boilers. The waste heat from a gas turbine can be used to raise steam, in a combined cycle plant that improves overall efficiency. Worldwide, most electric power is produced by steam–electric power plants. [1]

    One of the best-known designs is the Stone-Vapor. [3] [4] The inner casing of the boiler forms a vertical bell, with an outer airtight cylindrical casing. The oil or gas burner is mounted at the top, above the coils, and facing downwards. The heating element is a single tube, arranged into a number of helical cylinders. The first helices (in ...
