Higher effi ciency means less coal consumed and reduced emissions per unit of electricity. Th e chemical energy in the fuel can be expressed as either its Lower Heating Value (LHV) or its Higher Heating Value (HHV) [5]. In...

متن کاملThe Future of Coal (Chapters 1-3)
In the U.S., coal-based power generation is expanding again; in China, it is expanding very rapidly; and in India, it appears on the verge of rapid expansion. In all these countries and worldwide, the primary generating technology is pulverized coal (PC) combustion. PC combustion technology continues to undergo technological improvements that increase effi ciency and reduce emissions. However, ...
