现有燃煤电厂二氧化硫治理“十一五”规划研究

Research on the 11th Five-Year Plan for SO_2 Pollution Control of Existing Coal-Fired Power Plants

结合《现有燃煤电厂二氧化硫治理“十一五”规划》的编制背景,根据《国民经济和社会发展第十一个五年规划纲要》及相关法规、政策、标准等,重点分析了达标排放率、排放总量、排放绩效、脱硫机组容量等主要目标的选择及目标值的确定方法,并对“十一五”末全国电力二氧化硫排放量以及脱硫机组容量进行了预测.预计到2010年,全国电力二氧化硫排放总量将达到862×104t,比2005年减少33.7%;全国烟气脱硫机组投运及在建容量将达到3.8×108kW,占“十一五”末煤电装机总量的64.0%;全国燃煤电厂二氧化硫排放绩效指标由2005年的6.4 g/(kW.h)下降到2.7 g/(kW.h).同时进行了“十一五”现有燃煤电厂二氧化硫治理的投资分析与风险分析.提出通过完善二氧化硫总量控制制度,强化政策引导,加快脱硫产业化发展,充分发挥政府、行业组织和企业的作用确保目标的实现.

In combination with the background of the llth Five-Year Plan for SO2 pollution Control of Existing Coal-Fired Power Plants, and based on the draft Outline of the l lth Five-Year Plan for National Economic and Social Development and related regulations, policies and standards, the selection and determination method of the main targets, such as the up-to-standard emission rate, the total emission, the emission performance standard （EPS） and the flue gas desulfurization （FGD） capacity, etc., were analyzed. In addition, the SO2 emission and the FGD capacity of electricity industry in China by the end of the llth Five-year were forecasted. It was forecasted that by 2010, the total emission of SO2 from national electricity industry would decrease to 862 ×10^4 t, dropping by 33.7% as compared with the level of 2005; the FGD capacity putting into operation or under construction would reach 3.8×10^8 kW, accounting for 64.0% of the total capacity of national coal-fired generator at 2010; the EPS would drop to 2.7 g/（kW·h）, comparing with 6.4 g/（kW·h） at 2005. Subsequently, the investment and the risk about the SO2 pollution control of existing coal-fired power plants were analyzed. Suggestions were put forward that it is necessary to improve the system of total emission control of SO2, intensify policy guidance, expedite development of the FGD industrialization and make full use of government, organization and corporation, in order to guarantee the realization of the targets.
