    Firebox of a GWR 6959 Class steam locomotive, showing the underside of the brick arch, constructed from specially-shaped firebricks. Empty firebox of a Baureihe 52, showing the brick arch There is a large brick arch (made from fire brick ) attached to the front wall (boiler throat plate) of the firebox immediately beneath the firetubes.

  3. Flue-gas stack - Wikipedia

    en.wikipedia.org/wiki/Flue-gas_stack

    A flue gas stack at GRES-2 Power Station in Ekibastuz, Kazakhstan, the tallest of its kind in the world (420 meters or 1,380 feet) [1]. A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which flue gases are exhausted to the outside air.

  4. Fireless locomotive - Wikipedia

    en.wikipedia.org/wiki/Fireless_locomotive

    Fireless steam locomotive being recharged with high-pressure steam at Leicester power station in 1967. A fireless steam locomotive is similar to a conventional steam locomotive, but has a reservoir, known as a steam accumulator, instead of a boiler. This reservoir is charged with superheated water under pressure from a stationary boiler.

  5. History of the steam engine - Wikipedia

    en.wikipedia.org/wiki/History_of_the_steam_engine

    Steam ejected tangentially from nozzles caused a pivoted ball to rotate. This suggests that the conversion of steam pressure into mechanical movement was known in Roman Egypt in the 1st century, however, its thermal efficiency was low. Heron also devised a machine that used air heated in an altar fire to displace a quantity of water from a ...

  6. Combined gas and steam - Wikipedia

    en.wikipedia.org/wiki/Combined_gas_and_steam

    A turbo-electric COGAS power-plant. In this way, some of the otherwise lost energy can be reclaimed and the specific fuel consumption of the plant can be decreased. Large (land-based) electric powerplants built using this combined cycle can reach conversion efficiencies of over 60%.

  7. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is often hydrogen production , although syngas has multiple other uses such as production of ammonia or methanol .
