Title: Improved apparatus for attachment to boilers for the combustion of wet fuel such as megass and the like
IPC: F23G5/24
Filed: 1928-12-24
Abstract: 329,687. Mattekovich, R. von. Dec. 24, 1928. Charges, agitating.-In a furnace for consuming wet fuel such as megass the fuel is fed through a chute 1 on the uppermost of a series of superposed floors 31 in the dessicator, each composed of inner and outer supporting rings 32, 33, Fig. 8, connected by four radial perforated plates or trays 34 and carrying spaced loose trays 35 similar to the trays 34. The lowest floor 30 is built of blocks of refractory material. A tube 36 surrounding the upper metallic portion of the central air duct 10, and rotated by worm gearing, carries blades 39 which spread the fuel in the top compartment and are arranged sufficiently above the top floor 31 for the layer of fuel below them to form a seal for the furnace gases. The tube 36 also carries scrapers rotating over the floors 31 to cause the fuel to fall through the spaces of one floor to the trays of the next, and through the floor 30 into the combustion chamber. The scraper of the top floor consists of a bar 58, Fig. 9 having a curved inner and straight outer portion, that employed for the floor 30 being similar to the curved portion of the bar 58 without the straight end, and extending only to the inner ends of the radial slots in the floor through which the fuel falls. The scrapers used on the intermediate floors 31 are shown in Fig. 15, and comprise a frame 62, 64, 67 freely pivoted on a pipe 66 extending radially from the rotating tube 36. The frame, not being balanced on the pipe 66, rides loosely over the floor with the rear member 64 in contact with it and the shorter front member 67 raised about an inch from it. The upper portion of the layer of fuel is thus first removed by the scraper 67, and the lower portion is removed subsequently by the scraper 64, the upper and lower layers of the fuel thus being reversed on reaching the succeeding floor.
