Abstract

This invention relates to a plant in which dust is moved and which has a device to protect it against the explosion of dust materials. The plant includes a first apparatus (11), e.g. a container and a second apparatus (15) which is connected to the first by means of a connecting pipe (14), a decoupling valve (20) being arranged in the connecting pipe (14), which valve (20) is triggered by a central control unit (19). As soon as a signal transmitter in a pressure-relief device (13a) in the region of a quadrant pipe (16) detects a pressure peak in the connecting pipe, a signal is emitted to the central control unit (19), which without delay triggers the decoupling valve (20) and closes the connecting pipe (14), so that the apparatus (15) arranged downstream is protected against a flame spreading through the connecting pipe. <IMAGE>
