[ Objective] To investigate the types and distribution of the occupational hazard factorsin the coal-fired power plants.

The authors discuss the grave impact of coal mining, coal proces sing, coal transportation and coal utilization on the environment and estimate r oughly the economic losses caused by coal-fired power generation which are cons idered and added to the cost of coal-fired power generation and then compared w ith the costs of renewable energy-fired power generation.

Combined with its applications in the coal-fired power generation engineering,the prospect of using ASPEN PLUS is proposed.

In the next 10-20 years,the coal-fired power generation technology will still dominate domestic power generation industry.

In accordance with the relevant national standards and electri power industry s standards and specifications,the constractions of limestone-gypsum wet method flue gas desulfurization(FGD) facilities in one coal-fired power plant in south China,from the quality of design,anticorrosion of flue gas duct,erection technology to the import equipment,packing box and tank structures etc.

In order to compare the influence of the environmental cost on the electricity price among different types of power plants , the theory of environmental economics is applied in this paper to estimate the environmental cost of coal-fired power plant, natural-gas-fired power plant and nuclear power pla.
