the remote operated chokes with electric drive are installed at the airways the gas temperature in the pyrogas combustion chamber is about 1250 u00b0 c the high temperature in comparison with prototype allows making the conversion of non combusted particles more complete these particles are generated as a result of hydrocarbon combustion in the shaft furnace smoke fumes having combustion chamber temperature go to the bottom part of evaporating heat exchanger 14 from combustion chamber 13 through lined gas flue the evaporating heat exchanger is a hollow lined cylindrical apparatus where a gas quenching to temperature of 200 u00b0 c is going on it is provided by evaporation of pneumatic jet sprayed flushing solution mixed with air three jets are installed in the upper part of evaporating heat exchanger the flushing solution volume is automatically adjusted by electric drive gates depending on the smoke fumes temperature after evaporating heat exchanger the gas quenching from 1250 to 200 u00b0 c allows the prevention of dioxin formation after evaporating heat exchanger 14 off gas goes to the parallel bag filters 15 where a main amount of solid aerosol particles dust is catching one filter is main working apparatus another one is reserved the filters work in non stop mode there is air blowback regeneration then the pressure more than 1 5 u2212 2 kpa then the regeneration is not enough or residue activity is high the filter is changing the dust after regeneration is collecting in the bag filter bin then waste treatment is finished the dust goes to.
