Waste Heat Reduction and Recovery for Improving Furnace

large amount of the heat supplied is wasted in the form of exhaust or flue gases. These losses depend on vari-ous factors associated with the design and operation of the heating equipment. This technical brief is a guide to help plant operators reduce waste heat losses associated with the heating equipment.

Condensing boiler - Wikipedia

Since the final exhaust from a condensing boiler has a lower temperature than the exhaust from an atmospheric boiler 38 °C (100 °F) vs. 204 °C (400 °F) a mechanical fan is always required to expel it, with the additional benefit of allowing the use of low-temperature exhaust piping (typically PVC in domestic applications) without insulation

Boiler Efficiency - an overview | ScienceDirect Topics

Insulate the jacket of the boiler to reduce heat losses. The improvement of the boiler efficiency depends on the surface temperature. • Install soot-blowers to remove boiler tube deposits that reduce heat transfer between the hot combustion gas and the water. The improvement in the boiler efficiency depends on the flue gas temperature. •

Evaporator (marine) - Wikipedia

Working under vacuum also reduces the temperature required to boil seawater and thus permits evaporators to be used with lower-temperature waste heat from the diesel cooling system. Scale. One of the greatest operational problems with an evaporator is the build-up of scale. Its design is tailored to reduce this, and to make its cleaning as

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

Gas central heating boilers and furnaces - How do they work?

Aug 09, 2020 · Artwork: How a modern condensing boiler works. Left: In a traditional (non-condensing) boiler, hot exhaust gases leave the combustion chamber through a flue (1), helped on their way by an electric fan (not shown); they take heat with them, reducing the boiler's efficiency by as much as a third.
