Abstract
For sanitary disposal of sewage sludge, a new incinerating method with high performance is studied. In the first part, two types of atomizing apparatus, by which dewatered sludge is fed to furnaces in particulated form, are developed. One is the evaporation type atomizer, in which dewatered sludge is pressur ized, heated and fushed out from a nozzle to atmospheric pressure, then a part of water in the sludge is instantaneously evaporated at the outlet of the nozzle and the sludge is atomized into very fine particles. The other is the air jet type atomizer, in which sludge flow from a nozzle is atomized by high speed air jet.
