Abstract
Abstract A plant for the gasification of fossil fuels which includes a reactor container and a further plant component attachable to the reactor container. The reactor container has a discharge opening and includes a connection part extending outwardly from the discharge opening. A fireproof lining, which determines the inner cross-sectional area of the container, is provided within the container. An intermediate ring is interposed between the connecting part of the reactor container and the further plant component for attaching the connecting part to the further plant component. This intermediate ring is provided with a fireproof lining having an area of reduced inner cross-section which is less than the inner cross-sectional area of the fireproof lining of the reactor container, the area of reduced cross-section being the smallest cross-sectional area in the connection between the reactor container and the further plant component.

Claim 1
Independent Claim
230 words
A plant for the gasification of fossil fuels which includes a reactor container and a further plant component attached to said container, said reactor container having a longitudinal axis, a fireproof lining which determines the inner cross-sectional area of said container, a discharge opening and a connecting part extending outwardly from said discharge opening, said connecting part having an outer casing surrounding a fireproof lining thereof and forming an annular space therebetween; wherein, the improvement comprises an intermediate ring interposed between said connecting part and said further plant component for attaching said connecting part to said further plant component, said intermediate ring including a fireproof lining having a reduced inner cross-sectional area at a portion thereof which is less than the inner cross-sectional area of the fireproof lining of said reactor container, said reduced cross-sectional area being the smallest cross-sectional area of the connection between said reactor container and said further plant component; and wherein said intermediate ring further includes an outer casing surrounding the fireproof lining thereof and forming an annular space therebetween, the outer casing of said intermediate ring having one end adjacent the outer casing of said connecting part and being sealingly engaged therewith; and which plant further comprises a support structure attached to the outer casing of said intermediate ring and the fireproof lining of said ring for suspending the fireproof lining of said intermediate ring.
Claim 2
Dependent Claim
230 words
A plant for the gasification of fossil fuels which includes a reactor container and a further plant component attached to said container, said reactor container having a longitudinal axis, a fireproof lining which determines the inner cross-sectional area of said container, a discharge opening and a connecting part extending outwardly from said discharge opening, said connecting part having an outer casing surrounding a fireproof lining thereof and forming an annular space therebetween; wherein, the improvement comprises an intermediate ring interposed between said connecting part and said further plant component for attaching said connecting part to said further plant component, said intermediate ring including a fireproof lining having a reduced inner cross-sectional area at a portion thereof which is less than the inner cross-sectional area of the fireproof lining of said reactor container, said reduced cross-sectional area being the smallest cross-sectional area of the connection between said reactor container and said further plant component; and wherein said intermediate ring further includes an outer casing surrounding the fireproof lining thereof and forming an annular space therebetween, the outer casing of said intermediate ring having one end adjacent the outer casing of said connecting part and being sealingly engaged therewith; and which plant further comprises a support structure attached to the outer casing of said intermediate ring and the fireproof lining of said ring for suspending the fireproof lining of said intermediate ring.
Claim 3
