整体立式无机热传导型换热器在热风炉的应用实践

The Application of Whole Vertical Inorganic Heat Conduction Type Heat Exchanger to the Hot-blast Stove

介绍了高炉的热风炉采用整体立式无机热传导换热器的技术特点,并着重阐述在生产应用所采取的措施,以期达到了合理利用热风炉排烟余热,预热烧炉用的空、煤气,加快煤气燃烧反应速度,使得热风炉拱顶升温速度加快、升温期缩短、保温期延长,确保最终实现了热风炉送风温度提高的目的。

The thesis will introduce technical features of vertical type inorganic heat conduction heat exchanger.Specific measures are taken in the application of hot air furnace to utilize hot-blast stove exhaust heatto preheat air and coal gas and accelerate the pace of gas combustion reaction.The temperature of hot-blast stove arch roof increases faster with shorter period and the incubation period is prolonged.In this way,we finally achieve the temperature increase of the hot-blast stove.
