大型火电机组湿烟囱排放的研究

Research on moisture in exhaust gas discharge by stack in water coolling tower a large capacity fossil power unit

阐述了火电厂湿法烟气脱硫装置中烟气加热器的运行特点,对脱硫装置采用湿烟囱排放的可行性和存在的问题进行了分析,对脱硫装置提出了改进措施。建议采用钛和钛铂合金复合板作烟囱内筒,可以降低烟气对烟囱的腐蚀,延长烟囱的使用寿命。

exhaust gas heater＇s operating features in wet exhaust gas desulphunzation equipment for fossil - fired power plant wcre discussed, and the feasibility of using wet stack emission for desulphurization equipment and probiems existed were analyzed, measures to improve desulphurization equipment were presented, suggesting ,that titanium or titanium- platinum alloy compound plate be used as chimney lining to decrease the corrosion degree of exhaust gas to stack and extend its service life.
