Flue Gas Heat Recovery systems (FGHRS): Data …

2013-4-16 · Flue gas heat recovery systems (FGHRS) are designed to recover heat in the flue gases discharged from a boiler. They use the cold temperature of the domestic cold water supply to recover extra heat that is not extracted by the boiler. The amount of heat that can be extracted by a boiler is usually limited by the

Flue Gas Density Calculator - Home • FGKH

Flue Gas Density Calculator is based on Ideal Gas Law. The flue gas density of a flue gas can be measured using the ideal gas law. It has to be assumed that a real gas behaves as an ideal gas; this assumption is true when gas is at low pressure, so molecular interactions don't affect the system.

Flue-gas stack - Wikipedia

2019-10-1 · 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 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

Flue Gas - an overview ScienceDirect Topics

The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.
