4 The advantage of waste heat for heating is obvious in terms of saving investment in heat source and substation and saving the fuel.从节约热源和换热站投资以及节约燃料的角度看,余热供暖的 优点很明显. But the challenge lies in business Model: How to integrate the industrial waste heat into the existing heat source technically and financially 但挑战表现在商业模式方面: 如何从技术和资金角度将工业余热纳入现有热源.
