Waste heat recovery system - uses refrigerant circulating between evaporator to extract heat and condenser transferring it to cold stream

摘要

Recovery of waste heat from exhaust gas streams employs a conventional refrigeration cycle, based on freon or ammonia, to extract heat in an evaporator placed in the waste gas stream. Relatively small dia. pipework connects the evaporator to a condenser located in the gas stream which is to receive the recovered heat as latent heat of condensn. of the refrigerant. Used for waste heat recovery esp. from waste streams in the malting industry.
