High Efficiency Boilers | Is a Combi Boiler for You

Mar 16, 2020 · These boilers work by recovering heat from the flue gases that simply exit a house from the flue of a conventional non-condensing boiler. They condense the water vapor from those gases and recover heat that would otherwise be lost. One indication of the extra heat extracted is that the gases coming out of the flue in a condensing boiler have a

Natural Gas Heating Systems | American Gas Association

The combustion of natural gas produces byproducts of water vapor and carbon dioxide, which are the same elements exhaled when people breathe. These flue gases must be vented to the outdoors. Wall vents can be used for mid- and high efficiency natural gas forced-air furnaces, thus eliminating the need for the standard chimney and/or chimney liner.

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

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
