掺烧超设计值高硫褐煤设备问题探讨

Discussion on the problem of adding high sulfur lignite with super design value

某电厂脱硫改造后的机组在低负荷下脱硫处理能力裕量较大,为掺烧高硫份煤提供必要条件。需要在环保达标排放及相关设备安全稳定运行前提下,采取有效措施,尽可能增加高硫褐煤掺烧量,提高机组运行经济性。本文依据典型机组实际高硫褐煤掺烧经验,为实施过脱硫深度改造的机组掺烧高硫褐煤提供参考。

The capacity of desulphurization treatment of a power plant after desulphurization is large under low load,which provides necessary conditions for blending high sulfur coal.The effective measures should be taken on the premise of the discharge of environmental standards and the safe and stable operation of the related equipment to increase the combustion of high sulfur lignite as much as possible to improve the economy of the operation of the unit.Based on the experience of the actual high sulfur lignite Blended Combustion of a typical unit,this paper provides reference for the incorporation of high sulfur lignite in the unit with the depth of desulphurization.
