Boiler (power generation) - Wikipedia

The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.. Solid fuel firing. In order to create optimum burning characteristics of the fire, air needs to be supplied

Liquefied natural gas - Wikipedia

Liquefied natural gas (LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).. LNG is odorless, colorless, non-toxic and non-corrosive.
