Abstract
China is in the process of industrialization and electricity is indispensable for rapid growth. At the same time, the “coal-based” energy structure in China will not change perennially, which means, the development of power industry will be subject to the constraints of resources and environment for a long period of time. Therefore, according to the development of electric power industry, energy saving and emission reduction will be an eternal theme. The first part of this essay is the presentation of current situation and achievements. The second part, we summarize five most significant problems existed in current situation. According to the deficiency, we provide improvement measures and suggestions from seven aspects including structure adjustment, internal management, market means and legal system, etc, in order to promote the energy saving and reduce emission smoothly and successfully in the thermal plants in China.
Highlights
The emission of nitrogen oxides has been initially controlled
In 2007, fly ash discharged by coal fired power plants is about 380 million tons nationwide, which increased about 3% comparing with that in 2006
The comprehensive utilization rate of fly ash by the coal-fired power plants is 69%, which increased by 3%; the comprehensive utilization of fly ash is 260 million tons, with the rising amplitude of 13%
Summary
With the sustained and rapid development of the power industry and the promotion of the government and the enterprises themselves, remarkable achievements have been made in the field of energy saving and emission reduction, but there are still some problems as below: 2.1 Both construction quality and operational effectiveness of desulphurization facilities need to be improved. The whole capacity of small thermal units is about 100 million KW; the proportion is high in the northeast and northwest region of China, which results in high coal consumption for power supply. The development momentum of a few high energy-consuming and self-supply power plants in some areas has not been effectively controlled. These plants are of small capacities, inadequate environmental protection facilities and non-standard management. The cost of environmental governance has not been reflected in reasonable price system which brings in series influences on the promotion of energy saving and emission reduction
