Abstract
Abstract A device for the complete combustion of gaseous waste products comprising a refractory chamber divided by means of a refractory wall into interconnecting first and second compartments which have an increasing internal cross-section from the point of gas entry to gas exit, and air being introduced in controlled amounts into the stream of gaseous wastes as it traverses the length of the chamber via the first and second compartments. Supplementary heating means are provided in the first compartment to raise the temperature above the point of combustion of the gas/air mixture whenever required.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
An afterburner device for the substantially complete combustion of gaseous waste products which comprises a refractory chamber divided into a first compartment and a second compartment, a sloping elongated refractory wall in said chamber partially situate between and forming said first and second compartments and allowing passage therebetween, entrance means provided in said first compartment for the introduction of combustible gaseous waste thereto and exit means provided in said second compartment for the emission of combusted gaseous waste therefrom, said first and second compartments having an increasing internal cross-section from gaseous entrance to exit means, the length and slope of said refractory wall maintaining said internal cross-section, and fluent oxidant in controlled amounts being introducible into the stream of gaseous waste as it flows turbulently through said refractory chamber.
Claim 2
Dependent Claim
129 words
An afterburner device for the substantially complete combustion of gaseous waste products which comprises a refractory chamber divided into a first compartment and a second compartment, a sloping elongated refractory wall in said chamber partially situate between and forming said first and second compartments and allowing passage therebetween, entrance means provided in said first compartment for the introduction of combustible gaseous waste thereto and exit means provided in said second compartment for the emission of combusted gaseous waste therefrom, said first and second compartments having an increasing internal cross-section from gaseous entrance to exit means, the length and slope of said refractory wall maintaining said internal cross-section, and fluent oxidant in controlled amounts being introducible into the stream of gaseous waste as it flows turbulently through said refractory chamber.
Claim 3
Dependent Claim
25 words
A device according to claim 1 wherein supplementary heating means are further provided in said compartment for supplemental heating of the introduced combustible gaseous waste.
Claim 4
Dependent Claim
16 words
A device according to claim 1 wherein said sloping refractory wall has an arch-shaped transverse cross-section.
Claim 5
Dependent Claim
31 words
A device according to claim 1 wherein said fluent oxidant is introduced into the stream of gaseous waste at a plurality of spaced intervals and at planes non-parallel to said stream.
