Abstract
Abstract A gas generator for both upward and downward gasification, comprises a housing defining a combustion space, a cinder bath space below the combustion space and a space below the cinder bath space, the space below the cinder bath space being in communication with the combustion space; a main pipe leading upwards to the combustion space, the main pipe having an air inlet and a gas outlet above the air inlet, the gas outlet, when open, opening into the space below the cinder bath space; apparatus for opening and closing the air inlet and the gas outlet; and a serpentine passageway arranged around the housing and in communication with the space below the cinder bath space. In operation, the gas outlet is closed and the air during downward gasification inlet is open to allow air to be drawn by suction through the air inlet and up the main pipe into the combustion space, and gas generated in the combustion space flows into the space below the cinder bath space and thence through the serpentine passageway. During upward gasification, the gas outlet is open and the air inlet is closed and air is introduced into the combustion space and the cinder bath space, gas generated in the combustion space flowing down the main pipe and through the gas outlet into the space below the cinder bath space and thence through the serpentine passageway.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
265 words
A GAS GENERATOR FOR BOTH UPWARD AND DOWNWARD GASIFICATION, COMPRISING: A HOUSING DEFINING A COMBUSTION SPACE, A CINDER BATH SPACE BELOW THE COMBUSTION SPACE, AND A ZONE FORMED BY A SPACE IN THE HOUSING BELOW THE CINDER BATH SPACE, THE SPACE BELOW THE CINDER BATH SPACE BEING ARRANGED IN COMMUNICATION WITH THE COMBUSTION SPACE, NOZZLES ARRANGED FOR FEEDING AIR INTO THE COMBUSTION SPACE AND THE CINDER BATH SPACE, A VERTICAL MAIN PIPE IN COMMUNICATION WITH THE COMBUSTION SPACE, THE MAIN PIPE HAVING AN AIR INLET AND A GAS OUTLET ABOVE THE AIR INLET, THE GAS OUTLET, WHEN OPEN, OPENING INTO THE SPACE BELOW THE CINDER BATH SPACE, MEANS FOR OPENING AND CLOSING THE AIR INLET, MEANS FOR OPENING AND CLOSING THE GAS OUTLET, AND MEANS DEFINING A SERPENTINE PASSAGEWAY ARRANGED AROUND THE HOUSING AND IN COMMUNICATION WITH THE SPACE BELOW THE CINDER BATH SPACE, THE ABOVE GAS GENERATOR PERMITTING DOWNWARD AND UPWARD GASIFICATION, THE GAS OUTLET BEING CLOSED AND THE AIR INLET OPEN DURING DOWNWARD GASIFICATION TO ALLOW AIR TO BE DRAWN BY SUCTION THROUGH THE AIR INLET AND UP THE MAIN PIPE INTO THE COMBUSTION SPACE AND GAS GENERATED IN THE COMBUSTION SPACE FLOWING INTO THE SPACE BELOW THE CINDER BATH SPACE AND THENCE THROUGH THE SERPENTINE PASSAGEWAY, AND THE GAS OUTLET BEING OPEN AND THE AIR INLET CLOSED DURING UPWARD GASIFICATION AND AIR INTRODUCED INTO THE COMBUSTION SPACE AND THE CINDER BATH SPACE, GAS GENERATED IN THE COMBUSTION SPACE FLOWWING DOWN THE MAIN PIPE AND THROUGH THE GAS OUTLET INTO THE SPACE BELOW THE CINDER BATH SPACE AND THENCE THROUGH THE SERPENITINE PASSAGEWAY.

Claim 3
Dependent Claim
78 words
A gas generator as claimed in claim 1, wherein means for rotating the vertical pipe is provided and the means for opening and closing the air inlet comprises a closure member carried by the lower end of the main pipe, which closure member cooperates with a stationary closure member, so that in one angular position of the main pipe the air inlet is open and in another angular position of the main pipe the air inlet is closed.
Claim 4
Dependent Claim
56 words
A gas generator as claimed in claim 1, wherein the means for opening and closing the air inlet is operatively connected to the means for opening and closing the gas outlet so that when the gas outlet is open the air inlet is closed and when the gas inlet is closed the air inlet is open.
Claim 5
Dependent Claim
26 words
A gas generator as claimed in claim 1, wherein the means for opening and closing the air inlet comprises a half-cover and an electromagnetically controlled flap.
Claim 6
Dependent Claim
37 words
A gas generator as claimed in claim 1, wherein some of the nozzles open into the combustion space above and adjacent a fuel-supporting platform and the other nozzles open into the cinder bath space below the platform.
Claim 7
Dependent Claim
19 words
A gas generator as claimed in claim 1, wherein the nozzles pass through gas passages constituting said serpentine passageway.
Claim 8
Dependent Claim
37 words
A gas generator as claimed in claim 1, wherein pivotable members are mounted on a fuel supporting platform forming the bottom of the combustion space and rigidly connected to the main pipe, the main pipe being rotatable.
Claim 9
Dependent Claim
65 words
A gas generator as claimed in claim 1, wherein the gas passageway is constituted by the serpentine passages some of which extend upwardly from a region surrounding the lower portion of the combustion space and the upper portion of the cinder bath space and some of which project downwardly from that region, the passages projecting upwardly having a different vertical extent to those projecting downwardly.
