徐钢4号55m~3小高炉自七三年三月十四日——四月十二日和五月二十一日——五月二十五日试验喷吹焦炉煤气。在这期间共断续喷吹二十四次,最长一次喷吹时间为32小时。现把工艺情况简要介绍如下:一、喷吹工艺流程焦炉煤气来自焦化车间,经煤气总管,通过水封、过滤器,送往压缩机站。煤气经压缩机加压后通过贮气罐、煤气主管、煤气围管、煤气支管,用橡胶管连接喷枪。喷枪以15度角斜插至直吹管内,喷咀在风口前把煤气喷入高炉。在直吹管内段.喷枪用水套冷却保护。
XCMG No.4 55m ~ 3 blast furnace coke oven gas was tested from March 14 to April 12, and May 21 to May 25, 1973. During this period a total of intermittent injection twenty-four times, the longest injection time of 32 hours. Process conditions are briefly described as follows: First, the injection process coke oven gas from the coking plant, the gas mains, through the water seal, filters, sent to the compressor station. Gas pressurized by the compressor through the gas tank, gas chief, gas pipe, gas manifold, with a rubber hose connected to the gun. The spray gun is inserted into the straight blow pipe at a 15 degree angle and the nozzle injects the gas into the blast furnace before the tuyere. In the straight tube section, the gun is cooled and protected by a water jacket.
