摘　　要：针对国内火力发电厂烟囱现状和愈来愈高的安全经济运行要求，提出了开发和应用多管烟囱的必要性。根据烟气抬升的基本理论，采用有害物质落地一次最大浓度为标准比较分析了各种烟囱方案的环境效益。同时，用经济分析的动态指标考查了分期建设电厂单管和多管烟囱方案的经济性，还定性讨论了多管烟囱的可靠性，认为多管烟囱是很有发展前途的新型烟囱。结合秦皇岛热电厂烟囱方案的选择，论证了该三管集束烟囱的可行性。The necessacity to develop and apply a multi-tube chimney is presented by comparising the more and more requirements for the safty and economical operation of the conventional chimney in the present power plant in China. Based on the basical principle of rising and buoyancy effect, the comparison of different designs in the environmental protetion effect is proceeded by using the stanadard of the maximum concentration of harmful pollutant falling down once on the earth,meanwhile the economy of multi-tube chimney design is also analyzed by using the dynamic criterion in economic analysis ,the reliability of multitube chimney is also discussed resulting in a conclusion of that the multi-tube chimney will be a new-type of chimney having a bright future for its development. Finally,a feasibility study on the three-tube chimney used in Qinhuangdao Power Plant is also revealed.
