WASTE TO ENERGY COMBUSTION SYSTEM

摘要

A waste to energy combustion system (100), the system comprising a hydraulic ram feeder (104), a proprietary air injection system (106), a primary chamber which is a rotary kiln incinerator (108) and a bottom ash handling system (114). The proprietary air injection system (106) comprises a plurality of air injection nozzles directed tangentially and in the opposite direction of kiln rotation supplying combustion air into the rotary kiln incinerator (108) while inducing a vortex motion, which impinges turbulently against the waste as it rotates and burns and a plurality of water nozzles supplied through a conduit in an air duct having means for quenching to reduce temperature of exhaust gases and to reduce calorific value of waste. A secondary chamber (112) of waste to energy comprises of an air delivery system, a pressure relief valve, a burner and a detection mechanism. The secondary chamber (112) comprises means for receiving flue gas with more resident time, which exits from the rotary kiln incinerator, means for oxidizing residual flue gasses by applying air and heat and means for detecting a need for further combustion through the detection mechanism.
