| In the process of refuse incineration, the technologies of cogerneration and magnetic separation are adopted to revover and reuse electricity and waste metals. Refuse incineration produces the high-temperature waste heat. It goes through the heat transfer processes of radiation, transmission, and tran-sfer ing the heat recovery boiler. Then, the waste heat passes a series of heat exchange courses in the superheater, evaporator and econimizer. Each heat recovery boiler is able to generate high-temperature steam of 400℃. Such high-temperature steam supplies heat energy to plant facilities and the warm-water swimming pool of mutual beneficial facilities. in addition, such energy can produce a great volume of electricity by steam turbine generator. The electricity generated supplies the demand of the Plant, and the excess is sold to the Power Company as well. With regard to the recovery of waste metals, the slag produced after incineration will be delivered to the vibration slag conveyor by the drive device. Then the magnetic separator will sieve out waste metals from the slag and recover them for reuse. |
