Industrial waste heat recovery opportunities

Different industrial processes consume different amounts of energy and produce different amounts and qualities of waste heat. Therefore, in order to take advantage of the potential of industrial waste heat, it is necessary to study and analyze industrial processes used in large energy consumption industries, and to study which suitable waste heat recovery devices can be applied to the systems of each industry.

China's largest industrial waste heat is mainly related to the cement, ceramics, steel, oil refineries, glass manufacturing, chemicals, paper and pulp, and food and beverage industries. . When considering waste heat recovery options for industrial processes, it is important to check the source and usefulness of the waste heat generated and find out which waste heat recovery method is the most appropriate.

In this article, the steel, ceramics and food industries have been selected to study how to optimize energy management in each sector by using waste heat recovery systems. The above industries were selected for further investigation of WHR applications to indicate how and how WHR technology can be applied to different industries and production processes that exhibit all waste heat temperature ranges (low-high).

Waste heat of the steel industry

Steel production is a resource and energy intensive process involving a large amount of heat and raw materials. Waste heat recovery in the steel industry includes the recovery of heat dissipated from high-temperature sources, such as furnaces used for sintering, coke, iron, and steel production, which have been surveyed to account for about 8% of total industrial energy consumption. United Kingdom [4].

A common method of waste heat recovery in the steel industry is clean airflow from the production process. For example, Jouhara et al. [158] It was demonstrated in an experiment that the use of a flat heat pipe (FHP) in a steel wire cooling line of a steel production facility can provide up to 15.6 (kW) of heat recovery for a heat source of 450 ° C. In this experiment, an innovative FHP model was created, measuring 1 meter high by 1 meter wide, and tested at the hottest spot in the cooling zone of the production line. The model added water at a flow rate of 0.38 kg / s, and the hot gas dispersed from the process hit a flat heat pipe plate at an angle to the horizontal direction.
