Abstract
Abstract The reactor for producing gas from powdery fuels comprises an outer metal sheet jacket, an inner pressure resistant jacket defining with the outer jacekt a first interspace for a cooling liquid, reinforcing brick lining adjoining the inner wall of the inner jacket, a cooling shield enclosing a reaction chamber and defining with the brick lining a second interspace for an inert cooling fluid. The cooling shield has at its upper end a gap communicating with the second interspace and the lower end of the reactor is provided with a pressure releasing conduit communicating with the bottom of the second interspace so that when the gas generating process is interrupted and the conduit is opened the pressurized gas escapes from the reactor chamber through the upper gap and flows through the major part of the second interspace to be cooled down before the discharge from the connecting conduit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
204 words
An upright reactor for producing gas from powdery fuels, comprising an outer jacket; an inner jacket defining with the outer jacket a first interspace for a cooling liquid; a reinforcing lining adjoining the inner wall of said inner jacket; a cooling shield enclosing a reaction chamber and defining with said lining a second interspace for an inert gas; a gap formed in said shield to establish a communication between said second interspace and said reaction chamber, said first interspace being in non-communicating relationship with said reaction chamber and said second interspace; a burner insert communicating with the upper end of said reaction chamber; a discharge conduit means communicating with the lower part of said reaction chamber to discharge produced gases and liquid slag, said burner insert and said discharge conduit means passing, respectively, through the outer jacket, the inner jacket, the reinforcing lining and the cooling shield; and at least one outer connecting conduit communicating with said second interspace at a point remote from said gap including means to feed inert gas to said second interspace and, when the gas generating process as interrupted, means to release pressurized gases from said reaction chamber via the gap and a major part of said second interspace.
Claim 2
Dependent Claim
204 words
An upright reactor for producing gas from powdery fuels, comprising an outer jacket; an inner jacket defining with the outer jacket a first interspace for a cooling liquid; a reinforcing lining adjoining the inner wall of said inner jacket; a cooling shield enclosing a reaction chamber and defining with said lining a second interspace for an inert gas; a gap formed in said shield to establish a communication between said second interspace and said reaction chamber, said first interspace being in non-communicating relationship with said reaction chamber and said second interspace; a burner insert communicating with the upper end of said reaction chamber; a discharge conduit means communicating with the lower part of said reaction chamber to discharge produced gases and liquid slag, said burner insert and said discharge conduit means passing, respectively, through the outer jacket, the inner jacket, the reinforcing lining and the cooling shield; and at least one outer connecting conduit communicating with said second interspace at a point remote from said gap including means to feed inert gas to said second interspace and, when the gas generating process as interrupted, means to release pressurized gases from said reaction chamber via the gap and a major part of said second interspace.
Claim 3
Dependent Claim
61 words
The reactor as defined in claim 1 wherein said jackets and said shield have an upright cylindrical wall closed by arched end portions, said gap being formed in said shield between the transition line of said cylindrical wall and the upper end portion, and said outer connecting conduit communicating with said second interspace in the lower end portion of said reactor.
Claim 4
Dependent Claim
39 words
The reactor as defined in claim 1 wherein said outer connecting conduit has a branch for introducing said inert gas into said second interspace and a normally closed second branch for discharging the pressure gases from said reaction chamber.
Claim 5
Dependent Claim
227 words
An upright cylindrical reactor for producing pressurized gas from powdery fuels, comprising an outer jacket; an inner jacket defining with the outer jacket a first interspace for a cooling liquid; a reinforcing lining adjoining the inner wall of said inner jacket; a cooling shield enclosing a reaction chamber and defining with said lining a second interspace for an inert cooling fluid; a gap formed in said shield to establish a communication between said second interspace and said reaction chamber, said first interspace being in non-communicating relationship with said reaction chamber and said second interspace; an outer connecting conduit for applying inert gas to said second interspace; a burner insert communicating with the reaction chamber by passing through the upper end of the reactor through the outer jacket, the inner jacket, the reinforcing lining and the cooling shield and opening into the reaction chamber; a discharge opening means located at the lower end of the reaction chamber passing through the cooling shield, the reinforcing lining, the inner jacket and the outer jacket for discharging produced gases and liquid slag; and another outer connecting conduit communicating with said second interspace at a point remote from said gap to release in the event of an interruption of the gas generating process the pressurized gas flowing from said reaction chamber via the gap and a major part of said second interspace.
Claim 6
Dependent Claim
227 words
An upright cylindrical reactor for producing pressurized gas from powdery fuels, comprising an outer jacket; an inner jacket defining with the outer jacket a first interspace for a cooling liquid; a reinforcing lining adjoining the inner wall of said inner jacket; a cooling shield enclosing a reaction chamber and defining with said lining a second interspace for an inert cooling fluid; a gap formed in said shield to establish a communication between said second interspace and said reaction chamber, said first interspace being in non-communicating relationship with said reaction chamber and said second interspace; an outer connecting conduit for applying inert gas to said second interspace; a burner insert communicating with the reaction chamber by passing through the upper end of the reactor through the outer jacket, the inner jacket, the reinforcing lining and the cooling shield and opening into the reaction chamber; a discharge opening means located at the lower end of the reaction chamber passing through the cooling shield, the reinforcing lining, the inner jacket and the outer jacket for discharging produced gases and liquid slag; and another outer connecting conduit communicating with said second interspace at a point remote from said gap to release in the event of an interruption of the gas generating process the pressurized gas flowing from said reaction chamber via the gap and a major part of said second interspace.
Claim 7
Dependent Claim
28 words
The reactor as defined in claim 4 wherein the connecting conduit for introducing said inert gas into said second interspace is spaced apart from said other connecting conduit.
