针对目前火力发电厂建设的新形势,着重介绍了在采用湿法脱硫、不上GGH和取消烟气旁路的工艺前提下,采用整体多点超静定悬挂钢内筒烟囱新型结构的设计优化思路.同时依托工程计算分析可知,整体多点超静定悬挂钢内筒烟囱新型结构与传统整体自立式钢内筒烟囱相比具有明显的优势,可取得较好的社会经济效益,具有较好的推广前景.
In view of the new situation of thermal power plant construction at present, this paper mainly introduces the design optimization of the new structure of the whole multi-point ultra-statically suspended steel tube chimney under the premise of using wet desulfurization, not GGH and eliminating the flue gas bypass Thinking at the same time relying on engineering calculation and analysis shows that the overall multi-point statically indeterminate hanging steel chimney within the new structure compared with the traditional overall free-standing steel chimney has obvious advantages, can achieve better social and economic benefits, with better The promotion of prospects.
