当前,能源分级利用的理念已成为全社会的共识。但多数企业能源分级后可以回收却无处利用,这是企业节能降耗的最大瓶颈。通过不同行业企业间合作的方式消化这些回收的能源,也就是将高品位能源需求单位回收的废热,提供给低品位能源需求单位使用,是解决这一问题的可行之策。基于经济性角度出发,采用这种企业互补的模式需考虑能源输送成本,以厂址位置毗邻为佳。这就需要规划主管部门在未来产业布局 At present, the concept of graded energy utilization has become the consensus of the whole society. However, most enterprises can recycle energy after grading but nowhere to use, which is the biggest bottleneck in corporate energy saving. Digesting these recovered energy through cooperation among enterprises in different industries, that is, providing waste heat recovered by high-grade energy demand units to low-grade energy demand units is a feasible solution to this problem. Based on the economic point of view, using such a complementary business model to consider the cost of energy transport, the location of the site adjacent to the better. This requires planning authorities in the future layout of industries
