Abstract
Abstract A boiler in which a plurality of generally A-shaped tubes connect to, and are rotatably driven with, an annular hub and a steam discharge pipe in a generally circular chamber. Water and fuel for combustion are introduced through the hub. The tubes act like an impeller fan drawing air for combustion through the hub. The chamber is double-walled to define an air cooling jacket and air is drawn through the double wall before being directed to the hub.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A steam generating boiler comprising, in combination, a generally circular chamber, an annular hub mounted for rotation in said chamber, a steam discharge pipe mounted for rotation in said chamber in alinement with said hub, a plurality of tubes in an annular array with each tube opening into said hub and into said pipe, means for rotating said hub, pipe and tubes, means for introducing water into said hub so that centrifugal force carries water into said tubes, means including a fuel line in said hub for creating and maintaining combustion in said chamber so as to generate steam in said tubes which flows to said pipe, said tubes being generally A-shaped with the legs connecting respectively to said hub and said pipe and the apex defining a generally circular water circulation path whch rotates in the heat of said combustion.
Claim 2
Dependent Claim
141 words
A steam generating boiler comprising, in combination, a generally circular chamber, an annular hub mounted for rotation in said chamber, a steam discharge pipe mounted for rotation in said chamber in alinement with said hub, a plurality of tubes in an annular array with each tube opening into said hub and into said pipe, means for rotating said hub, pipe and tubes, means for introducing water into said hub so that centrifugal force carries water into said tubes, means including a fuel line in said hub for creating and maintaining combustion in said chamber so as to generate steam in said tubes which flows to said pipe, said tubes being generally A-shaped with the legs connecting respectively to said hub and said pipe and the apex defining a generally circular water circulation path whch rotates in the heat of said combustion.
Claim 3
Dependent Claim
49 words
The combination of claim 1 in which each of said tubes is formed with an air moving blade near its apex and said chamber is formed with a tangential exhaust passage so that rotation of the tubes creates an impeller fan effect drawing air for combustion through said hub.
Claim 4
Dependent Claim
46 words
The combination of claim 2 in which said chamber is formed of double walls defining an air cooling jacket with air inlet openings and air outlet conduits leading to said hub so that said impeller fan effect draws air between said double walls to the hub.
Claim 5
Dependent Claim
119 words
A steam generating boiler comprising, in combination, a generally circular chamber, an annular hub mounted for rotation in said chamber, a steam discharge pipe mounted for rotation in said chamber in alinement with said hub, a plurality of tubes in an annular array with each tube opening into said hub and into said pipe, means for rotating said hub, pipe and tubes, means for introducing water into said hub so that centrifugal force carries water into said tubes, means including a fuel line in said hub for creating and maintaining combustion in said chamber so as to generate steam in said tubes which flows to said pipe, said chamber being formed of double walls defining an air cooling jacket.
Claim 6
Dependent Claim
119 words
A steam generating boiler comprising, in combination, a generally circular chamber, an annular hub mounted for rotation in said chamber, a steam discharge pipe mounted for rotation in said chamber in alinement with said hub, a plurality of tubes in an annular array with each tube opening into said hub and into said pipe, means for rotating said hub, pipe and tubes, means for introducing water into said hub so that centrifugal force carries water into said tubes, means including a fuel line in said hub for creating and maintaining combustion in said chamber so as to generate steam in said tubes which flows to said pipe, said chamber being formed of double walls defining an air cooling jacket.
Claim 7
Dependent Claim
147 words
A steam generating boiler comprising, in combination, a generally circular chamber, an annular hub mounted for rotation in said chamber, a steam discharge pipe mounted for rotation in said chamber in alinement with said hub, a plurality of tubes in an annular array with each tube opening into said hub and into said pipe, means for rotating said hub, pipe and tubes, means for introducing water into said hub so that centrifugal force carries water into said tubes, means including a fuel line in said hub for creating and maintaining combustion in said chamber so as to generate steam in said tubes which flows to said pipe, said means for introducing water including a water line, and said hub having an open inner diameter sufficient to receive said fuel line and said water line while still permitting the free passage of air for combustion through the hub.
Claim 8
