Thermodynamic considerations in devising on external combustion gas turbine engine refuse incinerator

Abstract

Study and experiment indicate that, with existing technology, a modified open Brayton cycle can be used to burn common municipal refuse at atmospheric pressure and produce useful power while scrubbing the combustion product gases to remove pollutants.The hot combustion gases pass from a combustor through a turbine to a region below atmospheric pressure where they are scrubbed and cooled by mixing with water spray. The water spray and gas mixture is then exhausted to atmospheric pressure through a compressor.Although current compressor designs are workable in this application, a new design is needed which will have reduced water drag power loss.Ball State UniversityMuncie, IN 47306
