A new and improved incinerator steam generation system subjecting to combustion debris such as municipal waste, utilizing the heat derived therefrom to produce steam for steam boiler, electrical generating facilities, heating facility for industrial or commercial plants, and so forth. This is provided with a series of boilers and controls, both manually adjustable and also automatic, whereby the possibility of fire dangers are minimized, created temperature ranges of boiler gases are constrained to desirable limits, dump stack facilities are automatically controlled as to particular effectiveness for differing types of operating conditions, and where safety features are incorporated to shut down gas flow through the boiler during periods of boiler-water deficiency, excess steam generation relative to demand, and other conditions. Within the furnace area proper the pressure conditions are predetermined and are controlled during operation for desired efficiency, vapor removal, and materials\combustion. Thus, air-entrained particulates are minimized, and combustible gases as produced at the grate areas of the furnace are driven off for later, secondary combustion. Temperature control of resulting gases is maintained.

In combination, a furnace having: a declining, movable grate system provided with a feed end and an opposite discharge end; horizontally elongate housing means longitudinally receiving and essentially enclosing said grate system, provided with a feedstock access opening proximate said feed end, door means positioned at said access opening for selectively opening and closing the same, and having an updraft conduit structure proximately above said feed end, said updraft conduit structure being constructed and arranged to receive moisture and vapors from a proximal drying zone of said grate system proximate said feed end thereof, said drying zone being followed by a combustion zone horizontally displaced from said updraft conduit and then a residual zone remote from said updraft conduit and proximate said discharge end, said housing means having a top wall extending over said grate system at said combustion and residual zones of said grate system, said housing means also having first air-inlet means proximate said proximal drying zone for introducing a desired volume of air thereat, second air-inlet means proximate said combustion zone for introducing an increased volume of air thereat, and third constricted-air-inlet means proximate said residual zone for introducing a reduced volume of air thereat, said housing means thereby being constructed, by virtue of the inclusion of said first, second, and third air-inlet means, to produce an essentially quiescent area over said residual zone and a low velocity condition above said combustion zone, whereby to reduce to a desired minimum, entrainment of combustion-resultant particulates in gases rising from said grate system, said housing means also including a lower, water-seal discharge end proximate and beneath said grate system discharge end and remote from said updraft conduit structure.
