| Nowadays, our country energy use still has subject matter, such as low efficiency, bad economic efficiency, high environment pressure. Energy conservation, reducing energy consumption and improve energy utilization rate are important parts of energy development strategic planning, it’s fundamental way to solve our energy problems.China’s waste heat is rich in resources, widely exists in various professions production process, the afterheat resources approximately compose its fuel consumption total quantity17%~67%, may the returns-ratio reach60%, the afterheat use factor promotion space is big, the energy conservation potential is huge.This paper describes the characteristics of industrial waste heat, the industry afterheat use technology and industrial waste heat-based organic media at low temperature industrial waste heat power generation technology from a few technical details, and has forecast the industry afterheat technology development objectively.I,take the iron and steel companies for example, systematically elaborated the technical methods of industrial waste heat used in food cold storage, and has expressed an own view to food cold storage’s development condition and the tendency. |
