氧气顶吹转炉排气以CO为主。将其回收利用作热源的方法已被广泛采用。然而,由于吹氧冶炼,温度高达2000℃以上,其间将产生大量的微细氧化铁烟尘,这不仅直接降低了炼钢收得率,且在煤气回收过程中分离去除亦发生困难。为此需配备相应的排气 Oxygen top blowing converter exhaust to CO-based. The method of recycling it as a heat source has been widely adopted. However, due to the oxygen blowing smelting, the temperature is as high as above 2000 ° C, a large amount of fine iron oxide dust will be generated during this process. This not only directly reduces the steelmaking yield, but also separates and removes gas during the gas recovery process. To be equipped with the appropriate exhaust
