20080236457 | METHOD FOR TREATING BOTTOM ASH - A method for treating bottom ash from a waste incineration plant. The invention relates in particular to a method for treating bottom ash from a domestic waste incineration plant. In accordance with the invention bottom ash having a size ranging up to 2 mm is treated by removing a previously determined component. The treatment comprises at least one of the following steps: the removal of organic components, the removal of heavy metals, the removal of ions and the removal of a fraction having a size of up to 50 μm. It is preferred for the nonferrous heavy metals to be removed and the ferrous metals to remain in the fraction. Most preferably at least one of the treatment steps comprises a wet treatment. | 10-02-2008 |
20090173258 | System For Milling And Air-Water Cooling Bottom Ash From Heating Furnaces For Solid Fuels - The present invention relates to a milling and water-air combined cooling system for bottom ash from heating furnaces for solid fuels, able to maximize the efficiency in milling and cooling also large ash lumps at high temperature and in improving cooling air fluid dynamics which passes said system in counter-flow. The system comprises a crusher ( | 07-09-2009 |
20100064950 | Cooling System for Dry Extraction of Heavy Bottom Ash for Furnaces During the Storing Step at The Hopper - The present invention relates to a cooling system for dry extraction of heavy bottom ash output from furnaces for solid fuel during storing step at hopper, characterized by suitable air intakes ( | 03-18-2010 |

20110308435 | CONVEYING MEANS AND METHOD FOR CONVEYING HOT MATERIAL - A conveying means for hot material, including at least one conveyor belt and at least one housing at least partially surrounding the at least one conveyor belt, wherein at least one deflecting means for deflecting a gas flow flowing longitudinally with respect to the at least one conveyor belt towards the at least one conveyor belt is arranged in or on the housing, and wherein the gas flow can be deflected by the at least one deflecting means over at least 25% of a length of the at least one conveyor belt. | 12-22-2011 |
20120160141 | BOTTOM ASH DISCHARGING DEVICE FOR COAL-FIRED BOILER - A bottom ash discharging device for a coal-fired boiler including: a clinker case, installed between a bottom ash hopper outlet of the coal-fired boiler and a bottom ash conveyer, an impact bar including a plurality of heat-resistant metal rods supporting inside the clinker case, a clinker crusher, installed above the impact bar for crushing the clinker, and a guiding device, installed between the bottom ash hopper outlet and the clinker crusher for limiting the clinker to drop into the clinker crushing area of the clinker crusher. The bottom ash discharging device ensures that the clinkers drop from the bottom ash hopper outlet to the rear area of the clinker crusher, and that the impact bar can be replaced and repaired without stopping the coal-fired boiler. | 06-28-2012 |
20130284079 | SYSTEM AND METHOD FOR COOLING AND EXTRACTION OF HEAVY ASHES WITH INCREASE IN TOTAL BOILER EFFICIENCY - A cooling system for heavy ashes of the type adapted to be used in association with a combustion chamber, in particular for large flow rates of heavy ashes deriving, for example from solid fossil fuel, in an energy-production unit is described. The cooling system has: a transport belt for transporting the heavy ashes, adapted to be arranged below the combustion chamber and having a containment casing and a transport surface equipped with openings for the transit of cooling air, and cooling means for cooling the heavy ashes received on the transport surface. | 10-31-2013 |
