Design and application of flue gas condensate water recovery technology in gas heating system
摘要：
以北京市某供热厂烟气余热回收系统节能改造为例,提出了将锅炉产生的烟气冷凝水最大化收集处理,补充至供热厂一次管网乃至换热站二次管网系统的技术路线,并详细阐述了冷凝水利用的具体方案和控制策略。系统投用后节水效果显著,实现了提高燃气锅炉热效率、节能减排、保障供热系统高效经济运行的目的。
Abstract：
This study takes the energy-saving retrofit of a flue gas waste heat recovery system of a heating plant in Beijing as an example. It proposes a technical approach to maximize the collection and treatment of condensate water from boiler flue gas, which is then supplemented to the primary pipe network of the heating plant and even the secondary pipe network systems of heat exchange stations. This paper details the specific implementation scheme and control strategies for condensate water utilization. After system implementation, significant water-saving effects are achieved, successfully realizing the goals of improving gas boiler thermal efficiency, conserving energy, reducing emissions, and ensuring efficient and economical operation of the heating system.
