SYSTEM OF THERMAL DECOMPOSITION OF COMBUSTIBLE WASTES, AND METHOD OF WASTE UTILISATION BY MEANS OF THAT SYSTEM Russian patent published in 2013 - IPC F23G5/27 F23G5/14 

FIELD: power industry.

SUBSTANCE: processing system of combustible wastes by means of thermal decomposition consists of the following: waste incinerator including thermal decomposition chamber, through inner cavity of which several heat exchange tubes pass, and combustible wastes introduced to the chamber cavity are indirectly heated with the heat from heat exchange tubes, and subject to thermal decomposition and coking; combustion chamber arranged underneath from thermal decomposition chamber in an individual section, and providing the heat for waste decomposition, by supplying hot air through heat exchange tubes; water cooling chamber located in jacket of thermal decomposition chamber, into which recirculating cooling water is supplied; steam generator interconnected with thermal decomposition chamber through steam supply pipe and supplying the reheated water steam to thermal decomposition chamber; cooling plant interconnected with water cooling chamber through cooling water supply pipe and cooling water removal pipe, and pumping the cooling water through water cooling chamber; cleaner interconnected with thermal decomposition chamber through gas outlet pipe and removing noxious substances from inert gases and combustible gases supplied from thermal decomposition chamber; gas storage interconnected with cleaner through gas line and containing the purified combustible gas, some amount of which can be supplied to combustion chamber through circulation gas pipe; and cooling tower interconnected with waste heat recovery pipe connected to heat exchange pipes and cooling the hot air passing through it before it is discharged to atmosphere.

EFFECT: simpler design; reduction of power consumed for waste processing; providing efficient and safe waste processing.
