重庆九龙发电分公司重庆九龙发电分公司总经理王键亲自主持了脱硫装置GGH(烟气——烟气换热器)节能改造项目。将SGH(蒸汽——烟气换热器)创新改造为三维内肋管式GGH,解决了SGH能耗高,易腐蚀的不足,又避免了常规回转式GGH腐蚀、结垢、漏风问题,效果良好。该项目作为国际上首台管箱式GGH,于2008年5月在火电机组烟气脱硫中首次应用.至今已运行28013小时.
Wang Ji, general manager of Chongqing Kowloon Power Generation Branch of Chongqing Jiulong Power Generation Branch, personally presided over the energy-saving retrofit project of the desulphurization unit GGH (flue gas-flue gas heat exchanger). The SGH (steam - flue gas heat exchanger) innovation into three-dimensional fin tube GGH, to solve the SGH high energy consumption, easy to lack of corrosion, but also to avoid the conventional rotary GGH corrosion, scaling, air leakage problems, the effect good. As the first pipe-in-box GGH in the world, the project was first applied to flue gas desulfurization of thermal power units in May 2008. It has been operating for 28013 hours.
