How does combined heat and power (CHP) cogeneration work?

May 10, 2019 · Cogeneration (the alternative name for CHP) simply means that the electricity and heat are made at the same time. Artwork: How much more efficient is combined heat and power? A conventional plant is at best about 60 percent efficient (for every 100 tons of coal or other fuel it burns, 40 tons is completely wasted); a CHP plant can be 90 percent ...

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.
