Compared with the market-oriented reform process of coal, the marketization of China's power structure is relatively low. As Table 2 shows, although market-based 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 …

Coal mills or pulverizers play a very essential part in the coal-fired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion. Mills can be a bottleneck for the power generation process.
