简要介绍了近几年来中小型氮肥厂在煤造气技术改造中所取得的成果。并对如何进一步改造诸如中氮肥流程落后,设备陈旧、气化强度低、能耗高等问题进行了较详细论述。另外,还就专用炉箅问世、余热锅炉更新、鼓风机选型、微机换代、吹风气潜热回收技术的进展和自动加焦机发展趋势等也作了较全面论述。
This paper briefly introduces the achievements of small and medium-sized nitrogenous fertilizer plants in the technological transformation of coal gas production in recent years. And how to further reform, such as the backward process of nitrogen fertilizer, outdated equipment, gasification intensity is low, high energy consumption and other issues were discussed in more detail. In addition, it also made a more comprehensive discussion on the advent of special furnaces, renewal of waste heat boilers, selection of blowers, replacement of computers, development of latent heat recovery technology of blowing air, and the development trend of automatic coke oven.
