摘要： A shutoff device is provided for pulverized coal burners of a pulverized coal furnace. Each burner has a primary tube that conveys a pulverized coal/air mixture and is connected with a feed line for supplying the mixture to the respective burner. Disposed in the feed line, for closing off the same, is a slide valve that is provided with a valve plate. On the trailing side of the slide valve, the feed line is surrounded by an air receiver that is supplied with air. In the vicinity of the air receiver, an opening is provided in the wall of the feed line and can be closed off by a closure plate, which is synchronously actuatable with the slide valve such that in the closed position of the slide valve the opening is opened, and in the open position of the slide valve the opening is closed off.

摘要： In a delivery pipe for pulverized coal fines from a coal mill to a combustion chamber, a device for diffusing unevenly distributed coal flow evenly across the pipe. In a first form, the invention comprises a plurality of static, lateral, linear diffuser elements comprising rows of protrusions or teeth spaced laterally across the coal flow path in the pipe, preferably in a staggered and overlapping relationship. In a second form, the diffuser elements are rotatably mounted across the coal flow path in the pipe, and may be rotated at different speeds and in different directions. The diffuser elements spaced across the coal flow path in the pipe may be supplemented by peripherally-mounted diffuser elements at the inlet of that portion of the pipe or housing to provide an angled pre-diffusion of the coal flow from the sides of the pipe toward the lateral elements extending across the interior of the pipe.

摘要： A burner isolation valve or gate for use in the coal-delivery pipes of coal-fired power plants. Safety regulations often require that two valves be placed in the coal delivery line between a combustion chamber and an exhauster or pulverizer type deliver source to isolate the section of pipe in between for maintenance and other access. The invention includes a novel valve plate and actuation assembly, a novel housing adapted to sealingly enclose the valve plate, and a novel sealing mechanism for the valve plate and housing adapted to keep coal fines and dust out of the outboard portion of the housing in which the valve plate rests in the valve-open position.
