Carbon Waste Heat Boiler Operation

What is a Waste Heat Boiler? (with picture)

A waste heat boiler uses the heat formed as a byproduct of another process, heat which would normally be wasted, and uses it to create steam. The steam can be used to drive turbines which produce electricity. Alternatively, the boiler can simply be used to heat water or other kinds of fluid. As it recycles some of the energy used, a waste heat

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation Liming 17:02:11. Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat loss. The heat efficiency of a flue gas waste heat boiler is the percentage of the

Cogeneration - Wikipedia

Topping cycle plants primarily produce electricity from a steam turbine. Partly expanded steam is then condensed in a heating condensor at a temperature level that is suitable e.g. district heating or water desalination. Bottoming cycle plants produce high temperature heat for industrial processes, then a waste heat recovery boiler feeds an electrical plant.
