国内某钢铁厂360m~2烧结机余热回收发电项目设计

在钢铁生产过程中,烧结工序能耗差不多占整个企业能耗的10%,是仅次于炼铁的第二大耗能工序,而烧结工序中有50%左右的热能被烧结主抽烟气和冷却机废气带走,其中烧结机主抽烟道烟气余热占烧结工序能耗的13%～23%左右。这部分余热利用潜力是很大的,理论和工程实践证明,完全可以在保证烧结正常生产的前提下,根据废气温度级别,利用梯级取热的方法将热量重新分配,提高废气余热品位和利用价值,是企业创造经济效益,实施节能减排策略,发展循环经济的重要方式。

The Waste Heat Recovery of 360m~2 Sintering Machine of a Ateel Plant Project Design

In the steel production process, the energy consumption of sintering process energy consumption of the whole enterprise accounts for about 10%, is second only to the second energy consumption of ironmaking process and sintering process, heat energy about 50% by sintering main pumping smoke and exhaust cooling machine, wherein the main smoke flue gas waste heat of sintering machine, sintering energy consumption of 13% 23%. Use of this part of heat potential is very great, to prove the theory and engineering practice, can guarantee the normal sintering production, ac- cording to the exhaust gas temperature level, using the method of cascade heat will redistribute heat, improve quality and waste heat utilization value, is the enterprise to create economic benefits, the implementation of energy-saving emission reduction strategies, an important way for the development of circular economy.
