Design and analysis of waste heat utilization system for a wheel production line in Qinhuangdao

Presents the practical utilization of industrial mid and low temperature waste heat, including flue gas waste heat recovery and cooling water waste heat recovery. The waste heat boiler covers flue gas waste heat, while heat exchange system for cooling water waste heat recovery. The appropriate utilization of gas waste heat and cooling water waste heat improves the energy efficiency of the production line, reduces the consumption of natural gas, and satisfies the requirement of industrial green building design. Presents the waste heat capacity calculation, selection and design of waste heat boiler and waste heat recovery methods in the unstable smoke condition.
