inlet air flowrate for sludge for rotary dryer

Oct 01, 2016 Heat recovery between the sludge dryer outlet/inlet air is carried out by means of a water circuit which requires the use of two liquid/gas heat exchangers (HE1 and HE2) and a circulation pump (P1). The drawback of the system is the loss of heat from the constantly operating cooling scrubber CS (the heat is carried away by means of cooling water).
