摘要
多炉一塔脱硫工艺的烟气系统通常设置GGH和增压风机,但在工程实践中会出现较多运行问题,如失速、喘振、高能耗等。以某自备电厂3台220t/h燃煤锅炉烟气脱硫工程为例,针对多炉一塔湿法脱硫工艺是否设置GGH和增压风机进行了技术经济分析,并对烟气系统的控制监测方案进行了优化,最终采取了取消GGH、改造引风机、优化烟气系统控制监测的设计方案。可为小型燃煤电厂多炉一塔脱硫工艺提供参考。
The flue-gas system in wet flue gas desulfurization（FGD） for multi-boiler with one tower,is usually installed with the gas-gas heater（GGH） and booster fan,which might cause some operational problems in practice,such as the surge,stall,and high energy consumption.Based on the design of FGD for three coal-fired boilers（3×220t/h） in a thermal power plant,the economic and technical comparison were carried out for FGD process with or without the GGH and booster fan,in terms of performance,energy consumption,operation and maintenance cost.The flue gas control and monitoring system has been optimized.The conclusions can be used as a reference for flue gas wet desulfurization systems design in small coal-fired power plant.
