What is a Waste Heat Boiler? (with picture) - Info Bloom
Jan 31, 2022 · 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
