摘 要: | 湿法脱硫后较高的净烟气温度有助于烟气中污染物的扩散,但烟气换热器在工程应用中存在较多问题。通过对各种烟气再热技术进行分析比较,为某热电厂选择烟气-烟气热管换热和蒸汽-烟气列管换热串联组合应用的烟气再热技术,降低了设备出现腐蚀、堵塞的可能性,提高了系统运行稳定性。为其他工程湿法净烟气再热系统设计提供参考。

APPLICATION OF CLEAN FLUE GAS REHEAT TECHNOLOGY IN THE WET DESULFURIZATION |
| |
Abstract: | The higher temperature of the flue gas after wet desulfurization is helpful for its diffusion of pollutants into the air,but there are more problems existing in the engineering applications of gas-gas heaters. Based on comparison and analysis ofthe current flue gas reheating technologies,the comprehensive reheating technology compost of gas-gas heater and steam-gasheater was selected for a thermal power plant. It was proved to have the ability to reduce the possibility of corrosion as well asdevice blocking,and improve the operational stability of the system. So it can provide references for the similar wet flue gasreheat systems. |
