Abstract

Abstract 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 possiblity 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.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 196 words
An incinerator including, in combination: a housing having an ingress opening and a terminal egress; an overfeed grate system supported within said housing and comprising upper and lower, longitudinally aligned, declining, end-overlapping, longitudinally movable grates, said housing having a floor disposed beneath said grate system and opposite sides upstanding from said floor and enclosing said grate system, said housing also having a transverse structure disposed between and forming, substantially, air seals with said upper and lower grates proximate the end overlap thereof; means for introducing debris to be incinerated onto a forward end of said grate system for advancement toward the rearward end thereof, said grate system being air-pervious but forming with said housing a plenum beneath said grate system and a primary chamber above said grate system; a manifold ductwork having plural, mutually spaced branch ducts, said housing having mutually-spaced, air-admittance apertures communicating with the interior of said plenum and respectively coupled to said branch ducts; and blower means coupled to said manifold ductwork; wherein said branch ducts each have respective adjustable dampers and said housing includes depending, vertically open structure having terminal water seal means disposed rearwardly of said ductwork and said grate means.
Claim 2
Dependent Claim 196 words
An incinerator including, in combination: a housing having an ingress opening and a terminal egress; an overfeed grate system supported within said housing and comprising upper and lower, longitudinally aligned, declining, end-overlapping, longitudinally movable grates, said housing having a floor disposed beneath said grate system and opposite sides upstanding from said floor and enclosing said grate system, said housing also having a transverse structure disposed between and forming, substantially, air seals with said upper and lower grates proximate the end overlap thereof; means for introducing debris to be incinerated onto a forward end of said grate system for advancement toward the rearward end thereof, said grate system being air-pervious but forming with said housing a plenum beneath said grate system and a primary chamber above said grate system; a manifold ductwork having plural, mutually spaced branch ducts, said housing having mutually-spaced, air-admittance apertures communicating with the interior of said plenum and respectively coupled to said branch ducts; and blower means coupled to said manifold ductwork; wherein said branch ducts each have respective adjustable dampers and said housing includes depending, vertically open structure having terminal water seal means disposed rearwardly of said ductwork and said grate means.
Claim 3
Dependent Claim 16 words
The structure of claim 1 wherein said blower means is provided with variable air input means.
