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

Flue-gas stack - Wikipedia

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 combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

3.1 Stationary Gas Turbines

A gas turbine is an internal combustion engine that operates with rotary rather than reciprocating motion. Gas turbines are essentially composed of three major components: compressor, combustor, and power turbine. In the compressor section, ambient air is drawn in and compressed up to 30 times ambient

Performing a Combustion Analysis

Mar 03, 2008 · Carbon dioxide (CO2) reading: The CO2 level in the flue gas provides an indication of the efficiency of the combustion process. If the production of CO2 is as high as possible with slight excess air (complete combustion), the flue gas heat losses are at their lowest. The CO2 reading is calculated from the O2 reading by the analyzer.

Boiler - Energy Education

A final important design consideration is minimizing undesirable by-products in the form of ash and flue gas which pollute the environment. Types Solid fuel. Grate boiler: Coal or other solid fuels like biomass (about a few millimeters in diameter) are fed into the boiler from a hopper or conveyor belt. They move across a grate, which has air

1.4 Natural Gas Combustion - US EPA

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas

Dec 15, 2020 · For example, through exhaust gas recycling, in which flue gas from natural gas boiler (containing ∼4% Co2) is recycled and used in place of air for the fuel combustion, Co2 concentration in the flue gas can be enriched up to ∼8%, making Co2 capture less thermodynamically challenging (Vaccarelli et al., 2014).

Ventilation (architecture) - Wikipedia

Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives.
