摘要/Abstract

摘要： 根据国家下发的煤电节能减排升级与改造行动计划,全国火电机组在“十三五”期间须达到节能及超低排放目标,为了研究贵州省超临界W型火焰锅炉机组如何推行节能与超低排放改造,通过调研收集了国内已投运同类型机组能耗数据,对能耗水平进行对比分析,并通过实例分析贵州省内现役火电机组进行超低排放改造的投资及运行费用,分析结果表明贵州省W型火焰锅炉机组存在一定的特殊性,在节能和减排两方面较其他省份常规火电机组改造难度大、投资高,且改造后运行费用增加较多,建议提高政策支持力度。

Abstract: According to the upgrading and enhancement plan issued by the state for energy saving and emission reduction, all the thermal power generation units nationwide must meet the standard of energy saving and ultra-low emission during the 13th Five-Year Plan period. In order to figure out how to implement the plan for the supercritical units with W-type-flame boiler in Guizhou Province, the energy consumption data are collected for the same type of boilers that have already been put into operation. Then the level of energy consumption is compared and analyzed. In addition, the investment and operation costs of ultra-low emission modification are analyzed for the in-service units in the province through case studies. The results show that there are certain specialties of the W-type flame boilers in Guizhou, which means that the modification is more difficult and expensive in comparison with other provinces. The operation costs after modification will also increase more. Therefore, it is recommended that the policy support should be strengthened.

Key words: thermal power generating unit, ultra low emission, supercritical unit, W-flame boiler, flue gas, saving energy
