Abstract
A device for cooling hot, compressed, dust-laden gases. The device consists of an inner structure made out of cooled tubes, positioned inside a pressurized container. The device contains several straight partitions made out of tubes. The partitions parallel the longitudinal axis of the inner structure. The object is to redesign the heat-emitting surfaces of the device in order to make it more compact. At least one of the straight partitions is bent out into a nest of tubes. The nest extends through the cross-section of the inner structure. The tubes that the nest is made out of extend through and are supported by the rest of the partitions.

Apparatus for cooling hot, compressed, dust-laden gases, comprising:
- a gas-tight housing;
- an inner structure of cooled tubes located within said housing;
- said housing being pressurized;
- a plurality of straight planar tube partitions with tubes in said structure and parallel to a longitudinal axis of said structure;
- said planar partitions comprising heating surfaces in the form of webs;
- at least one of said tube partitions having substantially horizontal pipe sections bent out into a nest of tubes extending over the cross-section of said inner structure through the other partitions, said nest of tubes being supported by the remaining unbent tube partitions, part of vertical planar tube partitions comprising simultaneously heating surfaces and a support means, the remaining part of vertical planar tube partitions comprising a substantially horizontally-lying nest of tubes, said support means, vertical heating surfaces and horizontal heating surfaces being all formed from a single tube system.

- every set of three tubes in one partition having a middle tube bent out of a plane of the respective partition;
- webs connecting tubes on each side of a lane, tubes on each side of a lane comprising support means, said nest of tubes extending through said webs;
- a middle partition bent into a nest, tubes associated with each adjacent partition and remaining within a plane of the partition comprising support means;
- at least one nest having collector means located in said inner structure and extending through said straight partitions while being supported by said straight partitions, said collector means being secured by said bent-out tubes in a middle partition.
