| 6938563 | Grate furnace A grate furnace with a grate includes grate steps made of grate elements lying next to one another. Every second grate step in the longitudinal direction of the grate can be driven for carrying out stoking movements and the grate steps in each case lying therebetwee... | 09/06/2005 |
| 6814013 | Process for treating incineration residues from an incineration plant In the process for treating incineration residues from waste incineration plants, the incineration material is incinerated on a furnace grate. The incineration residues produced are quenched in a wet slag remover and conveyed out of the latter. The wet incineration ... | 11/09/2004 |
| 6796251 | Process for treating incineration residues from an incineration plant Incineration is controlled in such a way that a sintering and/or fusing of the slag takes place as early as in the incineration bed of the main incineration zone. The incineration residues produced are quenched in a wet slag remover and conveyed out of the latter. T... | 09/28/2004 |
| 6748882 | Process for influencing the properties of incineration residues from an incineration plant In a process for influencing the properties of incineration residues from an incineration plant, in particular a waste incineration plant, the incineration is controlled sot that a sintering and/or fusing of the slag takes place as earl as in the incineration bed of... | 06/15/2004 |
| 6378447 | Furnace with liquid-cooled grate elements and cooling circuit The furnace with liquid-cooled grate elements has an inflow and a return to these grate elements, the inflow and the return being connected to a condensation device open to the atmosphere. The inflow has arranged in it a U-shaped cooling-liquid seal, one ... | 04/30/2002 |
| 6067916 | Process and device for producing and utilizing gas from waste materials In a process for gasifying and burning waste materials, the waste materials are introduced into an incinerator (1) and end up on a burning grate (6) to which combustion air is conducted through various undergrate forced draft chambers (8a to 8e). In the f... | 05/30/2000 |
| 5762008 | Burning fuels, particularly for incinerating garbage A method for burning fuels, particularly garbage, in incinerators with a stoker grate, for which the primary air is supplied below the stoker grate into the fuel layer and the secondary air is supplied above the fuel layer, is controlled in such a way tha... | 06/09/1998 |
| 5711233 | Process and arrangement for the treatment of solid combustion residues in a combustion installation, in particular in a waste incineration plant The arrangement for treating combustion residues of a combustion installation comprises an ash discharger into which opens a fall shaft, into which the solid combustion residues fall from a furnace grate. The ash is conveyed from the ash discharger into t... | 01/27/1998 |
| 5634412 | Method for regulating the furnace in incineration plants in particular in refuse incineration plants To detect a regulating quantity which is directly proportional to the combustion temperature, an infrared measuring device in the form of an infrared pyrometer is provided in the descending waste gas flue of an incineration plant and measures the temperat... | 06/03/1997 |
| 5606924 | Process for regulating individual factors or all factors influencing combustion on a furnace grate To carry out a process for regulating individual factors or all factors influencing combustion on a furnace grate, a radar device is provided primarily. This radar device serves to detect the three-dimensional distribution of the fuel mass on at least one... | 03/04/1997 |
| 5241916 | Procedure for supplying combustion air and a furnace therefor The procedure for supplying combustion air during grate firings, in which the primary combustion air is introduced into the fuel, and secondary combustion air is introduced directly into the flow of exhaust gas, and in which, in addition, some of the exha... | 09/07/1993 |
| 5211926 | Process for extracting of disposing of ammonia or ammonia compounds from dust mixtures In order to recover or dispose of ammonia or ammonia compounds from mixtures of dust that occur during combustion processes, during subsequent gas cooling, or during subsequent gas scrubbing, the dust that is created is mixed in batches with water in a cl... | 05/18/1993 |
| 5123363 | Method and apparatus for reducing the nitric oxide concentration in the waste gas flow of combustion processes The method for reducing the nitric oxide concentration in the waste gas flow of combustion processes consists of the introduction of chemicals, e.g. ammonia, sal ammoniac, urea, calcium cyanamide, into the waste gas flow, wherein the waste gas flow is mar... | 06/23/1992 |
| 5009171 | Feed device with filling hopper and adjoining feed chute for feeding waste to incineration plants A feed device comprises a filling hopper, a feed chute and a plurality of feeding pistons arranged adjacent to one another on a feed table, each feeding piston carrying at least one retaining and compression body in the area of its front end. The retainin... | 04/23/1991 |
| 4953477 | Method and apparatus for regulating the furnace output of incineration plants For the purpose of regulating the furnace output of incineration plants with a combustion grate, the primary air supply is variously regulated by zones along the length of the grate as well as in the transverse direction of the combustion grate. A monitor... | 09/04/1990 |
| 4548139 | Grate for industrial furnaces A grate for industrial furnaces wherein pairs of stationary grate bars flank movable grate bars.
