Patent CA-2176658-A1 (CA)
Title: Cooled grate block
Inventor: HAUSER ROLF
IPC: F23H17/12
Filed: 1996-05-15
Abstract: For cooling a grate block which forms a part of a grate for plants for the thermal treatment of waste material, a closed cooling chamber inside a block body of the grate block below an upper wall bearing the waste material is filled with cooling water and is closed in a sealing manner from the bottom by a base provided with an insulation layer. Effective cooling of the parts of the grate block which are subject to the greatest thermal loading takes place, greatly reducing the temperatures. Since thermal expansions in the material are dispensed with, a grate-block row can be formed by only a few grate blocks screwed to one another. The assembly and exchange of grate blocks are simpler; and the undesirable dropping of waste material through the grate between the grate blocks is largely eliminated. Additionally, the grate blocks can be produced from less expensive material.

Title: Method and device for changing the temperature of a discrete material
Inventor: REICHELT HELMUT
IPC: B01J19/12
Filed: 1995-08-16
Abstract: The invention calls for a discrete material such as a gas, a liquid or a living being, to be exposed to electromagnetic radiation from a large-area irradiator, causing the molecules to resonate at their natural frequency and hence to become warmer. In order to lower the temperature of the material, the radiant energy emitted by it is extracted via a receive antenna, resulting in a loss in energy and hence cooling of the material. Working in an enclosed fluid-filled space, the fluid can also be included, by suitable choice of radiation spectrum, in the resonance interaction producing the warming or cooling effect.
