## Abstract

A coolable lining for a high-temperature gasification reactor, especially in the zone of a replaceable lower furnace, in which the refractory brickwork receives the melting liquid occurring in the melting operation during the gasification of household, industrial and special wastes. The refractory material, consisting of oxides of non-noble meals, is pierced at defined intervals by straight channels, into which it is possible to insert cooling elements that can be installed and removed from the outside.

## Claims

### Claim 1

A coolable lining for the lower replaceable half of a high-temperature gasification reactor which receives liquid metal material occurring during the gasification of municipal solid waste, the lining comprising: a refractory material brickwork consisting essentially of oxides of non-noble metals and formed about a generally vertical central axis, characterized by a plurality of channels spaced radially of the central axis in the refractory brickwork at defined intervals, a removable cooling element disposed in each of the channels, the channels and associated cooling elements arranged within the refractory brickwork in the shape of a polygon about the central axis.

### Claim 2 (depends on 1)

A coolable lining according to claim 1, characterized by the fact that each of the cooling elements include an outer tube having a closed bottom end and an open top end, and an inner tube concentrically disposed within the outer tube for the introduction and removal of the cooling medium, each of the cooling elements further including connectors extending from the open outer end for introduction and removal of the cooling medium.

### Claim 3 (depends on 1)

A coolable lining according to claim 1, characterized by the fact that the channels in the refractory brickwork have a larger interior diameter than the exterior diameter of the cooling elements, and that the interstitial space between the refractory brickwork and each cooling element is filled with a mechanically resilient heat-transfer medium.

### Claim 4 (depends on 3)

A coolable lining according to claim 3, characterized by the fact that the heat-transfer medium is felted metal wire.

### Claim 5 (depends on 1)

A coolable lining according to claim 1, characterized by the fact that adjacent channels are axially offset from one another.

### Claim 6 (depends on 5)

A coolable lining according to claim 5, characterized by the fact that the arrangement of a respective polygon is formed by blind holes of equal height in the refractory brickwork.

### Claim 7 (depends on 1)

A coolable lining according to claim 1, characterized by the fact that a sensor is associated with one of the cooling elements for monitoring temperature changes and leakages in the one cooling element.

### Claim 8 (depends on 7)

A coolable lining according to claim 7, characterized by the fact that a sensor is associated with each one of the cooling elements for monitoring temperature changes and leakages in the respective cooling element.

### Claim 9 (depends on 1)

A coolable lining according to claim 1, characterized by the fact that heat-conductive metal strands are incorporated into the refractory brickwork of the lining, at least in the zone around the cooling channels.
