boiler flue gas waste heat recovery technology

Waste heat recovery unit - Wikipedia

A waste heat recovery unit (WHRU) is an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency. The WHRU is a tool involved in cogeneration.Waste heat may be extracted from sources such as hot flue gases from a diesel generator, steam from cooling towers, or even waste water from

Waste Heat Recovery & Economisers - Turnbull & Scott

By capturing the waste heat in the flue gas with an economiser and diverting it to pre-heat the steam boiler feed water, the boiler thermal efficiency can be increased to as much as 95%. Improving thermal efficiency cuts fuel consumption resulting in significant cost savings often in the region of 4-6% p.a.

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.
