Compared with the marketoriented reform process of coal, the marketization of China's power structure is relatively low. As Table 2 shows, although marketbased reforms in both the power generation and coal industries began in the 1980s, the government still holds dominant control over the power generation industry. Coal fuel accounts for 60%70% of the cost of power generation, and the ...

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
