日本专利 公昭58—2 采用燃气透平高温排气来加热水,由此产生蒸汽驱动蒸汽透平的废热回收锅炉,由于其传热管的热膨胀会引起各种危害。这种废热回收系统见图1。 传热管有许多根,它们均被支撑板所支撑,汇总为一个接头,该接头接到圆形管座上(见图2,图3),以便穿过锅炉侧壁,即外部管道和传热管之间通过园形管座及接头进行连连(见图1)。由于传热管,接头及图形管座在发电厂运行时会被加热到几百度,传热管簇在长 Japanese Patent Publication No. 58-2 uses gas turbine high-temperature exhaust gas to heat water, thereby generating steam-driven steam turbine waste heat recovery boilers that cause various hazards due to the thermal expansion of their heat transfer tubes. This waste heat recovery system shown in Figure 1. The heat transfer tube has a number of roots, all of which are supported by the support plate and are grouped together into a joint which is attached to a circular stem (see Figure 2, Figure 3) so as to pass through the side wall of the boiler, Between the heat pipe through the garden socket and connector for repeated connections (see Figure 1). As heat transfer tubes, connectors and graphics tube base in the power plant operation will be heated to several hundred degrees, heat transfer tube cluster in the long
