heat recovery from boiler flue gas

WASTE HEAT RECOVERY TECHNOLOGIES FROM HEATING

Recovery of heat contained in the flue gas leads to the increase of thermal efficiency and thus to the decrease of boiler fuel consumption and pollutant emissions. To recover as much as possible of the waste heat, exhaust gas must be cooled deeper to recover both sensible heat of the flue gas and latent heat of water vapour from flue gas.

Heat Recovery | Resources & Guides | Carbon Trust

Heat recovery is the collection and re-use of heat arising from any process that would otherwise be lost. The process might be inherent to a building, such as space heating, ventilation and so on, or could be something carried out as part of business activity, such as the use of ovens, furnaces and the like.

Waste Heat Recovery - Zeeco, Inc.

Waste Heat Recovery. Waste heat recovery equipment reclaims heat from flue gas for use in other process units. The heat is transferred directly from the hot flue gas to a steam boiler or circulating thermal oil system. The quantity of flue gas and the associated exit gas temperature limit the amount of heat recovered.

Flue Gas Heat Recovery systems (FGHRS): Data requirements

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
