wastewater from coal fired boiler Agent

Utility systems - processdesign

Feb 22 2016 · The main advantage of cogeneration over coal-fired energy production is that heat is not wasted. In coal-fired processes heat is released and wasted during electricity generation. Cogeneration captures some if not all of the byproduct for heat which is an extremely useful utility that will be discussed in subsequent sections.
