洛林——南方连轧公司(索里梅)福斯厂2号高炉的3座热风炉安装了一台烟气显热回收装置,于1982年4月投入运行。该装置是以加压水为热媒体。由图1可见,热风炉烟气在从烟囱排出之前通过一台换热器,向加压水放热。吸热后的过热水进入两个不同的换热器,一个位于高炉煤气管道上,一个位于助燃空气管道上。过热水在这 Lorraine-South Rolling Company (Solimei) Fu Si plant No. 2 blast furnace three blast furnace installed a flue gas sensible heat recovery unit, put into operation in April 1982. The device is pressurized water for the heat medium. As can be seen from Figure 1, the flue gas from the hot blast stove passes through a heat exchanger before it is discharged from the chimney and radiates heat to the pressurized water. After the endothermic superheated water into two different heat exchangers, one located in the blast furnace gas pipeline, one located in the combustion air pipeline. Overheated water is here
