ABSTRACT:
An ashbox for the hearth of a furnace adapted to burn solid fuel, descending along in inclined grate as it burns. The ashbox comprises an extractor chamber having a concave bottom which is part-cylindrical with horizontal generatrices. This chamber is normally filled with water to a level below the upper edge of the chamber. A vertical clinker well terminates at a lower lip below the upper edge of the chamber and is immersed in the water in the chamber. A scraper blade is reciprocated perpendicularly to the generatrices of the concave bottom. An inclined wall merges at its lower end with the concave bottom of the chamber and has an overflow at its upper end above the normal level of the water in the chamber. The arrangement is such that the scraper blade pushes ash up over the overflow lip. The extractor chamber is in two parts and can be opened by relative displacement of these parts to provide vertical access to the ash well. One part of the chamber is a tilting part comprising the concave bottom and the scraper blade.
