4. Waste heat recovery from boiler exhaust flue gas. The heat loss in the exhaust flue gas is the largest heat loss in a power station boiler which typically accounts 70–80% of the total boiler heat losses . The temperature of the exhaust flue gas from a power station boiler generally ranges from 120–140°C.
2012-11-16 · After the waste heat boiler was brought back in service, immediate results showed that the process gas side temperature was reduced from 800ºF to 650ºF, or the original operating temperature specification. Thus, the heat transfer performance of this unit was brought back to design conditions and the overall plant efficiency was improved.
Boiler feed water A boiler is a device for generating steam, which consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam.
Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler.
The increasing concentration of suspended solids can form sludge that impairs the efficiency of the boiler and the capacity for heat transfer. Water must be periodically discharged or ” blown down ” from the boiler to control the concentrations of suspended and total dissolved solids in the boiler to avoid boiler …
