摘要:
The furnace has a feeding channel (4) through which firewood is transported into a fire chamber (3). A steam pipe (10) leads into the channel (4). Through said pipe (10), steam is introduced into the solid fuel material in bursts as soon as a certain temperature is exceeded within the said channel (4). The steam increases the humidity in the air and the moisture of the firewood, thereby reliably preventing a spreading of the fire within the feeding channel (4), without simultaneously impairing combustion within the fire chamber (3).

A device inhibiting propagation of explosions using a pipe having an inlet and an outlet. The inlet is connectable to a container to be protected or to a conduit to be protected. The device further includes a mechanism for building up a pressure difference so that a higher pressure is generated in a first region of the pipe located upstream of the outlet in the direction of the inlet and a lower pressure is generated in a second region located upstream of the first region in the direction of the inlet.

Apparatus for substantially blocking flames and spreading heated gases emitted from a broiler flue. The apparatus includes a riser placed above the broiler flue for defining a pathway along which heated gases are exhausted from the flue, a catalyst support on the riser for supporting a catalyst in the pathway for flow of heated gases through the catalyst from a bottom surface of the catalyst to a top surface of the catalyst, and a plurality of baffles in the riser extending across the pathway below the catalyst support. The baffles have the shape of inverted troughs.

AN AIR CLEANING SYSTEM FOR COOKING RANGES AND THE LIKE, ADAPTED TO REMOVE HEAT AND CONTAMINANTS SUCH AS GREASE-LADEN FUMES GENERATED FROM THE HEATING SURFACES OF SUCH RANGES, PROVIDING AN EXHAUST DUCT EXTENDED FROM A POSITION ADJACENT TO SAID HEATING SURFACE AT WHICH IT HAS AN INTAKE OPENING TO A REMOTE EXHAUST OPENING, SAID DUCT HAVING A CONSTRICTED PORTION OF THE DUCT, AND A PAN DISPOSED MEANS FOR DRAWING FUMES IN THE INTAKE OPENING FOR DISCHARGE FROM THE EXHAUST OPENING, A SPRAY BNATH LOCATED AT THE CONSTRICTED PORTION OF THE DUCT, AND A PAN DISPOSED BELOW THE BATH TO COLLECT SPRAY THEREFROM TOGETHER WITH CONTAMINANTS DISSOLVED THEREIN. THE STREAM OF AIR GENERATED THROUGH THE DUCT IS CLEANSED BY THE WASHING ACTION OF THE SPRAY BATH, THE COOLING EFFECT THEREOF RESULTING IN CONDENSATION OF VOLATILE CONTAMINANTS, AND BY SUCCESSIVE HUMIDIFICATION AND DEHUMIDIFICATION OF THE STREAM. THE INVENTION ALSO HAS TO DO WITH A UNIQUE FORM OF TRAP HAVING PARTICULARLY SIGNFICANT UTILIZATION IN THE SYSTEM.

A flame arrester/burner assembly with a multifarious arrester element for preventing deflagrations and extended endurance burning time (FABA-XT). The multifarious element flame arrester includes a pipe body having a first end and a second end, a first arrester element positioned within the pipe body adjacent the top end; a third arrester element adjacent the bottom end; and, a second arrester element positioned in the pipe body between the first arrester element and the second arrester element. The first, second, and/or third arrester elements may be of the same design or disparate designs. The FABA-XT of the present disclosure is an end-of-line burner element for use in VOC-Vapor Destruction Systems.

A fume production and treatment installation includes:a fume generator including at least one burner, a combustion chamber having at least one combustion hearth, and a fume exhaust outlet; and a confinement enclosure for confining the fumes produced by the fume generator, which enclosure has an inlet connected to the fume exhaust outlet for removing fumes from the combustion chamber, and an outlet connected to the fume generator via a fume recirculation circuit, the discharge from which into the combustion chamber being referred to as the “fume feed head”. The combustion chamber has a protective screen, interposed between the combustion hearth and the fume feed head, for protecting the feed head from the flame of the burner, the inlet for the fumes into the confinement enclosure is disposed in the upper third of the enclosure, and the confinement enclosure is equipped with a closable exhaust outlet for removing condensates.

An explosion protection venting system has a plurality of vessels or reactors connected by a common vent line. A flame front diverter having a pair of opposing rupturable discs is connected to each one of a plurality of vessels for directing a deflagration away from the normal flow path and through an alternate path that prevents damage to nearby structure.

An environmental detection system is particularly suited for elevator hoistways and other locations where access is difficult or restricted. The inventive system comprises a fire rated access cage which is disposed within the hoistway in a desired location, and is securely attached to an associated access panel, which is fire protection rated and positioned to extend through a wall defining the hoistway. An environmental sensing device, such as a smoke detector or heat sensor, is secured within the cage so that it is disposed within the hoistway, and can freely detect any smoke or excessive heat present in the hoistway because of a large number of apertures in the walls of the cage. The resultant system, thus, is constructed so that authorized personnel can access the environmental sensing unit conveniently through the access panel door from an adjacent hallway or room to test or maintain it, without shutting down the associated elevator or compromising the effectiveness of the unit.
摘要:
A fire extinguishing assembly is used in a ventilating duct which has an inner wall, an outer wall, and an insert hole that extends in a radial direction from the outer wall to the inner wall. The fire extinguishing assembly includes a mounting seat having an inner seat wall to be mounted on the outer wall of the duct to cover the insert hole, and an outer seat wall with an inner peripheral seat. The inner peripheral seat defines a through hole that extends to the inner seat wall, and an annular insert portion that extends from the inner seat wall and that is in fluid communication with the through hole. The insert portion can be inserted fittingly into the insert hole to establish fluid communication between the ventilating duct and the through hole. An elongate fire extinguishing body has a connecting end portion, a free end portion formed with a nozzle head that can be brought to pass through the insert portion to extend inwardly of the inner wall via the insert hole. A heat fusible and gas impermeable cap member has a closed end portion to isolate hermetically the nozzle head from an interior of the ventilating duct, and an annular end portion that is exposed outwardly of the duct through the through hole and that forms an annular edge. A mounting flange is integrally formed with and extends outwardly from the annular edge.
