湿法烟气脱硫系统GGH热态性能试验方法探讨

Thermal Performance Test Method for GGH in Wet Flue Gas Desulfurization System

烟气换热器(GGH)是火电厂燃煤机组湿法脱硫系统的重要组成部分。通过理论推导和现场试验研究,提出并归纳了湿法烟气脱硫系统GGH热态性能试验的方法、主要内容及注意事项,重点介绍了GGH泄漏率的测试要点,以期为GGH热态性能试验的实践提供建议和参考。

GGH（Gas Gas Heater） is an important part of wet flue gas desulfurization system in coal-fired unit.Through formula derivation and field test research,the paper proposes thermal performance test method,contents and cautions for GGH in the wet flue gas desulfurization system,with an emphasis on introducing the essentials of leakage rate test,and hope to provide a reference for the thermal performance test.
