Abstract Before finishing inspection and repair of dynamic equipment during overhaul, it was
designed to use vaporized liquid Nitrogen instead pressed air to thoroughly heat and purge e-
quipment inside cold box of air separator. Schemes for process flow revamping and attentions for safe-
ty were presented, and the feasibility of the schemes was analyzed. Taking KDON3200/ 7000 type air
separator as an example, parison before and after the revamp was made to it, to illus-
trate economic benefits and significance of the revamp.
Key words: air separator, optimal revamping, heating system, liquid Nitrogen vaporization sys-
tem, economic benefits
天华公司实施锅炉节能扩产技改
天华公司投资 5 亿元对原锅炉供热系统进行节能扩产技术改造, 建设 3 台 220 t/ h 循环流化床燃煤
锅炉及辅助设备、附属设施, 2 台运行, 1 台备用。该项目采用静电除尘器进行除尘, 氨法脱硫装置进行
脱硫, 新建 150m 烟囱排放燃煤烟气, 以先进的清洁生产燃烧技术取代陈旧的工艺, 达到节能减排增效
的目标。
该项目建成后, 2 台锅炉最大连续蒸发量工况运行时, 可供蒸汽 390t/ h, 不仅可满足天华公司生产
和发展的动力蒸汽负荷需要, 而且原有锅炉供热系统将停运, 可节约标煤 55250t/ a、节电 1. 1 @ 106kW#
h/ a、节水 92t/ a, 减排
