Steam locomotive - Wikipedia

How a steam locomotive works, in 100 words ; Coal or oil is directed into the firebox (item 27 in the large diagram below), where it burns at high temperature. The firebox is surrounded by water in the boiler, and many tubes (28) extend from the firebox's front along the boiler barrel (29). Very hot gases travel through these tubes and up the smokestack/chimney (33).

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

Jul 20, 2020 · 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 efficient or even more. That gives a huge saving in fuel and operating costs and a major environmental benefit.
