摘要:

以新疆地区某电厂2台200MW燃煤机组粉尘超低排放改造为例,对湿式电除尘技术方案和高效脱硫协同除尘技术方案进行了比较。两种技术方案均能满足出口粉尘质量浓度≤5mg/m3(标态、干基、6%O2)的要求:湿式电除尘技术方案对烟气负荷适应性更强,但投资及运行维护费用高;高效脱硫协同除尘技术方案具有投资少,运行成本低等优势。

Abstract:

Taking a dust emission reduction transformation of 2×200MW coalfired units in Xinjiang region as an example, it make a comparison with wet ESP technology and efficient desulfurization dust removal technology. Both of all can make the outlet dust emission concentration lower than the requirement, 5mg/m3(the state, dry basis, 6% O2): wet ESP technology can be more adaptable to wide variety of flue gas load, but investment and operation and maintenance costs were higher than efficient desulfurization dust removal technology; while efficient desulfurization dust removal technology possesses a lower investment and lower running cost.
