1. The steel industry. The waste heat generated in the production process of sintering, steel rolling, steelmaking and other processes in iron and steel enterprises is recycled and reused through reasonable cascade utilization, waste heat power generation, waste heat heating and other methods.

2. Non-ferrous industry. In the production process of electrolytic aluminum, alumina, copper and other industries, a large amount of waste heat is generated. The use of non-ferrous industry flue gas waste heat boilers and power generation devices, kiln flue gas radiation preheaters and exhaust gas heat exchangers can be used to generate waste heat for power generation. Improve the efficiency of resource utilization in the non-ferrous industry.

3. Cement industry. Recycle the waste heat from the kiln head and tail exhaust gas of the new dry-process cement rotary kiln and the waste heat on the surface of the rotary kiln shell. The main form of low-temperature waste heat power generation can be converted into high-quality electricity; the waste heat on the surface of the rotary kiln shell is heated in winter , Summer refrigeration, heating production media and other methods of recycling.

4. The glass industry. Using glass furnace waste heat comprehensive utilization, oxy-fuel combustion, and high-temperature batch pre-decomposition technology, the low-temperature waste heat resources of the float glass production line are recovered, and the flue gas waste heat discharged between the kiln head and the flue gas in the melting section of the glass furnace is used to generate electricity through low-temperature waste heat Equipment recycling.

5. Coal industry. The low-temperature waste heat resources discharged or generated by coal mine water, mine ventilation exhaust air, compressed air systems, etc., can be used to generate electricity through the available waste heat to achieve reasonable cascade utilization to meet the needs of refrigeration and heating places.

6. Petrochemical industry. Apply advanced coal gasification, advanced rectification, liquid caustic soda evaporation, ammonia vaporization waste liquid flash method to recover steam and other technologies, as well as new calcium carbide furnace, sulfuric acid waste heat power generation equipment, and use hydrogen chloride synthesis waste heat by-product middle and high pressure steam, vacuum distillation, dry ashing , Yellow phosphorus flue gas recycling, comprehensive utilization of calcium carbide furnace tail gas and other technologies to recover waste heat resources.

7. Printing and dyeing industry. The waste heat generated in the production process of the printing and dyeing industry can be utilized by using technologies such as high and medium temperature waste water and waste gas thermal energy recycling, high-efficiency energy-saving rewashing, and high-efficiency energy-saving spinning cooling, spinning heat medium circulation heating and other technologies and equipment, which can improve resource recycling. efficiency.

8. Paper industry. Through the use of waste heat recovery and utilization methods such as boiler pressure difference power generation, the paper-making production process is carried out to carry out the transformation of fully enclosed gas hood heat recovery and energy-saving technology, and the application of steam recovery technology in the production of chemical pulp is accelerated to use waste heat for power generation.
