工业企业余热和废热利用研究

摘要

工业余热和废热目前在我国的利用率较低，不但造成了能源的巨大浪费，而且直接或间接地造成了环境污染。以实际工程为例，从工程自身的热量需求情况出发，回收工艺副产蒸汽，实现了对余热的梯级综合利用。此余热梯级综合利用系统不但充分利用了工艺副产蒸汽，节约了运行费用，而且可以满足不同用户对热源的需要。%The low utilization of industrial waste heat in China not only creates a huge waste of energy, but also causes environmental pollution directly or indirectly. We researched the actual project. According to the heat demand of the project, we accomplish the cascade comprehensive utilization of waste heat by recycling the byproduct steam. The comprehensive utilization of waste heat cascade system will take full advantage of the byproduct steam in saving operating costs, and meet the heat source demands of various users.
