| 20110297061 | EXTRACTING AND COOLING SYSTEM FOR LARGE FLOWS OF HEAVY ASHES WITH EFFICIENCY INCREASE - The present invention relates to a system for extracting and recovering energy for large for large flows of heavy ashes produced by solid fuel boilers, able to decrease the final temperature of the extracted ash without increasing the air flow entering the boiler flue, usually fixed by the boiler designers at a value around 1.5% of the total combustion air. When the air flow needed to the cooling exceeds the maximum quantity allowable in the boiler, the system allows the air and the possible vapour to be sent to the air inletting duct entering the air/fume exchanger on the air side, thanks to a separation of the cooling environments made by the ash itself. The separation of the environments of the cooling system is handled automatically based upon a temperature signal of the ash to the discharge from the system. If the cooling air is not sufficient to cool down the ash, the cooling efficiency can be increased by the addition of nebulised water. | 12-08-2011 |
| 20120183376 | SYSTEM FOR EXTRACTION AND TRANSPORT OF LIGHT ASHES BY MEANS OF A STEEL BELT CONVEYOR - A transport apparatus for dry extraction and transport of fly ashes produced inside solid fuel boilers, adapted to be associated with a fume dedusting system and including: a metal belt conveyor, having a plurality of slats partially overlapped, adapted to support a bed of fly ashes to transport the bed along a preset path, and a sealed metal casing inside which the slats move; and containment means for fly ashes, adapted to confine the ashes on the slats and along the transport path so as to limit relative motion between ashes and conveyor, which means comprises transverse boards, leveling members, side boards and a movable rear baffle. | 07-19-2012 |
