Lean and clean: why modern coal-fired power plants are better

Jun 21, 2016 · At the heart of coal-fired electricity generation lies the steam cycle. Typically, pulverised coal is fed into a giant industrial furnace surrounded by boiler tubes filled with water. The burning coal heats the water to create steam, which is transferred at high-pressure to turbines linked to a generator.
