Abstract
Abstract A rotary kiln formed by a plurality of pipes joined to define an inner cylindrical surface and being interconnected to permit water flow through the pipes. Water from the pipes is circulated to a steam drum for steam removal. The pipes are joined so as to define a plurality of intermediate openings for gas porosity and provision is made for introducing controlled amounts of air into the kiln and for enclosing and capturing volatile gases generated by the burning. A nonclogging waste chute feeds the kiln, and an associated furnace both further utilizes the heat of combustion and provides a static burning location for exceptionally large items of waste.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A rotary kiln comprising, in combination, a plurality of pipes secured together to define an inner generally cylindrical surface, means mounting said plurality of pipes for rotation about the axis of said cylindrical surface with the axis being horizontally tilted so as to have a high end and a low end, means for rotating said plurality of pipes on said mounting, a feeding chute into which burnable waste material can be stacked which opens into the high end of said cylindrical surface, said pipes being interconnected for circulating water flow and having a water input line and a water discharge line, means for circulating water through said lines including a steam drum connected to said discharge line for separating steam from the water, said pipes being secured so as to define a plurality of intermediate openings so that said cylindrical surface is gas porous, and means for delivering controlled amounts of gas for burning through selected portions of said porous cylindrical surface.
Claim 2
Dependent Claim
162 words
A rotary kiln comprising, in combination, a plurality of pipes secured together to define an inner generally cylindrical surface, means mounting said plurality of pipes for rotation about the axis of said cylindrical surface with the axis being horizontally tilted so as to have a high end and a low end, means for rotating said plurality of pipes on said mounting, a feeding chute into which burnable waste material can be stacked which opens into the high end of said cylindrical surface, said pipes being interconnected for circulating water flow and having a water input line and a water discharge line, means for circulating water through said lines including a steam drum connected to said discharge line for separating steam from the water, said pipes being secured so as to define a plurality of intermediate openings so that said cylindrical surface is gas porous, and means for delivering controlled amounts of gas for burning through selected portions of said porous cylindrical surface.
Claim 3
Dependent Claim
69 words
The combination of claim 1 including a steam generating furnace disposed adjacent to said kiln with said low end opening into the furnace, said furnace including a plurality of boiler pipes opening into said steam drum, and said boiler pipes being formed to define a fire grate at the bottom of said furnace beneath the open lower end of said kiln for receiving incompletely consumed material for continued burning.
Claim 4
Dependent Claim
61 words
The combination of claim 1 in which said feeding chute has an upper end dimensioned to receive the largest sized unit to be burned in said kiln, said chute being tapered to increase in cross section from said upper end so as to be substantially nonclogging, and said water input line and water discharge line being located at said lower end.
Claim 5
Dependent Claim
32 words
The combination of claim 1 including means defining a chamber surrounding a portion of said pipes for receiving through said gas porous surface volatile gases generated by material burning within said surface.
