1. Thermal power generation is to use the heat energy generated when combustible substances are burned and convert it into electric energy through power generation devices. China is rich in coal resources. In 1990, it produced 1.09 million tons of coal, of which coal for power generation only accounted for 1.2%. Thermal power generation still has great potential.

2. Due to the shortage of fossil fuels on the earth, human beings are striving to develop nuclear power generation, nuclear fusion power generation and high-efficiency solar power generation, so as to finally solve the energy problems faced by human society. The earliest thermal power generation was realized in 1875 Paris North Station Thermal Power Plant. With the improvement of generator and steam turbine manufacturing technology, the improvement of power transmission and transformation technology, especially the emergence of power system and the demand of social electrification for electric energy, thermal power generation entered a period of great development after the 1930s. The capacity of thermal power generating set increased from 200 MW to 300 ~ 600 MW (mid-1950s) to 1973, and the maximum thermal power generating set reached 1300 MW. Large units and power plants have greatly improved the thermal efficiency of thermal power generation, and the construction investment and power generation cost per kilowatt are also decreasing. By the end of 1980s, the largest thermal power plant in the world was Kagoshima thermal power plant in Japan, with a power generation capacity of 4,400 MW. However, the ultra-large-scale unit has brought about the decline of reliability and availability, so by the early 1990 s, the capacity of a single thermal power plant was stable at 300~700 MW. , accounting for more than 70% of China's total installed capacity.

3. Thermal power generation is the main power generation mode in China. As one of the three main equipments in thermal power plants, utility boilers have developed with the development of thermal power industry in China. When environmental protection and energy saving became the important direction of structural adjustment of China electric power industry, the thermal power industry actively promoted the optimization and upgrading of industrial structure under the policy guidance of "big pressure and small pressure", and closed a large number of small thermal power units with low energy efficiency and heavy pollution, which greatly accelerated the upgrading of domestic thermal power equipment.
