摘要:

裂解气透平机冷凝器(E-131)的蒸汽凝液中二氧化硅分析指标超标且偏大,不仅造成锅炉给水总管中的二氧化硅指标达到高限值,且直接导致6号、7号裂解炉汽包所产超高压蒸汽二氧化硅指标大于20 μg/L,表明E-131内部管束有微量泄漏,管程中的循环水少量进入壳程中的凝液中。将E-131凝液切出锅炉给水系统,切入临时新增管线并直接送至公用工程装置闪蒸罐,对E-131进行检修消漏后,其凝液中二氧化硅指标正常。

Abstract:

The silica analysis index of steam condensate in condenser (E-131) of cracking gas turbine is high and exceeds the standards, not only causing the silica index in the boiler water supply main pipe to reach the high limit, but also directly resulting in the silica index of ultrahigh pressure steam produced by No. 6 and No. 7 furnace steam drum higher than 20 μg/L. This indicates that there is trace leakage in the internal tube bundle of E-131 and a small amount of circulating water in the tube side enters the condensate in the shell side. The condensate in E-131 is cut out of the boiler water supply system, cut into the temporary new pipeline and directly sent to the flash tank of the utilities. After the maintenance and leakage elimination of condenser E-131, the silica index of the condensate returned to normal.

Key words: turbine condenser leakage, silica exceeds the standards, quality of ultrahigh pressure steam, treatment measures
