Heating dried material by combustion flue gases - combines dried material pollutants with hot flue gases for combustion

摘要

The dried material emits pollutants discharged together with the combustion flue gases. The pollutants are combined with the hot combustion flue gases for their combustion. Pref. the pollutant combustion takes place prior to discharge together with flue gases. The drying chamber (1) heater has at least one inlet for the combustion flue gases, and at least one outlet. The chamber contains a heat exchanger (4) with inlet (5) and outlet (6), with it inlet spaced from the combustion flue gas inlet (2). The exchanger outlet forms the waste air outlet. ADVANTAGE - Low-pollutant design with increased operational economy.
