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.
