“二煤改一煤”,就是将合成氨生产中的燃料煤(烟煤)和原料煤(白煤),通过技改尽量减少生产用汽,充分回收和合理利用工艺余热,整个生产流程中能量得到合理平衡,并保证满足正常生产时(包括碳铵和
“Two coal to one coal” means that the fuel coal (bituminous coal) and raw material coal (white coal) in the production of synthetic ammonia are minimized through technological transformation, and full recovery and rational utilization of process waste heat is achieved, and energy is obtained in the entire production process. Reasonably balanced and guaranteed to meet normal production (including ammonium bicarbonate and
