小氮肥行业的合成氨蒸汽自给技术,是学习和消化吸收引进大合成氨生产装置,通过热能的综合平衡利用,实现余热发电和合成氨生产蒸汽自给的双重目标,采用这项措施后,生产合成氨不再用燃料煤,原来的“两煤”(原料煤和燃料煤)变成了“一煤”,能源消耗有较大幅度下降。 Small nitrogen fertilizer industry, ammonia self-supporting technology is to learn and digest and absorb the introduction of large ammonia plant, through the comprehensive utilization of heat energy to achieve the dual target of waste heat power generation and ammonia production of steam self-sufficiency, the use of this measure, the production of ammonia is no longer used Fuel coal, the original “two coal” (raw coal and fuel coal) into a “coal”, a more substantial decline in energy consumption.
