Autonomous system for discharging exit of smoke and hot gases in e.g. industrial building, has metal spacers provided with small opening, which is formed between adapter frame body and frame to pass flue gases and hot gases into blade fuse

摘要

The system has a profiled sheet (5) mounted in a cover. Two stiffeners are formed by two angle profiles (9, 10), which are attached to a frame (3). The profiled sheet is connected with end portions, and upstream and downstream of another frame (1). A blade fuse (16) is mounted on a rigid support (17) by a lattice part. An adapter frame (18) is fixed on an upper edge of the former frame. Metal spacers (19) are provided with a small opening, which is formed between the adapter frame and the former frame to pass flue gases and hot gases into the blade fuse.
