电力行业节能减排的作用和影响目前,我国电力消费能源在一次能源中占42%。其中,发电供热用煤占全国煤炭消费量的54%,预计2010年这一比例将达到58%。国家减排目标指二氧化硫和化学需氧量这两种主要污染物排放总量的减少。在全国排放量中,电力二氧化硫排放占51%,化学需氧量占1%,电力二氧化硫控制在全国减排目标中占举足轻重的地位。随着经济社会发展,电力 The role and impact of energy-saving emission reduction in the power industry At present, China’s power consumption accounts for 42% of primary energy. Among them, coal for power generation and heating accounts for 54% of the national coal consumption, and it is estimated that this proportion will reach 58% in 2010. National emission reduction targets refer to the reduction of total emissions of two major pollutants, sulfur dioxide and chemical oxygen demand. Among the national emissions, electricity sulfur dioxide emissions account for 51% and chemical oxygen demand accounts for 1%. Electricity sulfur dioxide control plays a decisive role in the national emission reduction targets. With the economic and social development, electricity
