Abstract
A slide arrangement for blocking or closing off a channel disposed between a coal pulverizer and coal dust burners, and conveying a gas having a high proportion of coal dust. The slide arrangement includes a housing disposed in the channel wall and a shroud or steel structure laterally connected to the housing. A passage for a slide plate is provided in a wall of the housing facing the shroud or steel structure. The passage can be closed off by a closure member except for a narrow gap. The closure member has a circumferential seal that rests against the rearward side of the housing wall. The closure member also has a wear plate that when the closure member is closed is flush with the inner side of the housing wall and forms a smooth passageway.
