A waste heat recovery unit 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 cooling processes such as in steel cooling.
The fuel burn rapidly and the bed attain a uniform temperature. In AFBC boiler combustion is take place at about 850- 950 degree Celsius. What are the things should be inspect during start up of AFBC boiler ? Start up inspection of afbc boiler: 1.All main hole doors are closed. 2. all drives, drag chain , pocket feeders are proper running condition. 3.
A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration ) or used to drive a steam turbine ( combined cycle ).
The Claus Waste Heat Boiler (WHB) is a critical piece of equipment in a Sulphur Recovery Unit (SRU); its fundamental purpose is as a heat transfer device used in energy recovery. Sulphur plant operators have recently been experiencing higher than normal WHB failure rates, perhaps from oxygen enrichment and pushing rates.
