| 中文摘要: |
| 新型干法线烧成系统的年运转率一般为85%，原料磨设计年运转率一般为60%，这25%的运转率差将导致原料磨停运期间的废热浪费；加上雨季和非雨季原料水分不同（多数原料雨季水分达3%~5%，非雨季则在2%以下），也导致非雨季时烘干热源未被充分利用，因此开发原料粉磨旁路热风余热回收发电系统有现实意义。在进行原料粉磨系统余热挖掘和余热量计算的基础上，对原料粉磨旁路废热回收系统进行了发电量的计算、发电系统装备的可行性分析以及工艺流程和布局的探讨等。 |
| 英文摘要: |
| The annual running rate of New dry process cement firing system is generally 85%, and the design running rate of raw material mill is about 60%， which means there is 25% running rate difference which will lead to heat wasting during outage of raw material mill. And moisture contents of raw material of rainy season and non rainy season are different(water content of most raw material in rainy season reaches 3%~5%, and 2% in non rainy season), which also results in drying heat being not fully utilized in non rainy season. So to develop waste heat recycling power generation system for bypass hot gas of raw material mill has practial significance. Based on the potential waste heat analysis and calculation, the capacity of power generation system was calculated, the feasibility of power generation equipment was analysed and the process and layout were discussed. |
