Effect Analysis of Fly Ash on the SO_2 Formation in Coal-fired Power Plants

摘要

In China, coal is mainly used and its consumption accounts for about 70% of total primary energy sources. Coal's burning will result in serious acid rain, water pollution, greenhouse effect, and other environmental pollutions. Now coals are mainly consumed by Coal-fired power plants. This paper analyzed effects of ash on the SO_2 formation in a 330MW coal-fired power plant. Through study and analysis, rules of the effects of contents of alkaline materials in ashes on the SO_2 emissions are gained.
