A passive explosion isolation valve (10) is provided that comprises vertically-oriented gate members (40, 42) configured to close automatically in response to an energetic event occurring downstream of the valve. The valve (10) may be optionally equipped with a valve seat cleaning assembly (46) configured to removed accumulated particulate material away from the area of the valve seat (48) and/or one or more latch assemblies (44) configured to secure the gate members (40, 42) in the closed position following closure of the valve (10) in response to an energetic event.

A flame arrester for a process device is provided. The flame arrester includes a flame arrester element formed of a first helix having a first axis and a second helix having a second axis, wherein the first axis and the second axis are unparallel. A housing configured to mount to the process device. The flame arrester element is mounted to the housing. A combustion analyzer employing an improved flame arrester is provided along with a method of manufacturing an improved flame arrester for process devices.

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.

An anti-fire safety system for a transport vehicle has one or more storage tanks storing hydrogen. The system includes a first hydrogen-releasing system, which is configured to release outside the vehicle hydrogen contained in at least one of the storage tanks. The system also includes a second release system, which is arranged to intervene and bypass the first hydrogen release system under predetermined operative conditions. The second release system is configured to transform by a chemical reaction, at least a part of the bypassed hydrogen flowing outward from at least one storage tank, into at least one different substance.

A vent assembly (200) comprises a housing (13), a flow conduit (10) and a weather hood (12), the flow conduit (10) having a proximal end (10A) for being fluidly connected to a source of material and an open distal end (10B), the housing (13) having a base portion (13A), a side wall portion (13B), and a top portion (13C), the flow conduit (10) comprising a baffle (12E) located between the base portion (13A) and the top portion (13C) of the housing (13) to direct fluid flowing from the flow conduit (10) towards the weather hood (12) and through the housing (13) in a direction towards the top portion (13C) of the housing (13).

Described herein is a kitchen ventilation system, comprising: a kitchen hood communicative with a kitchen exhaust duct; a fan communicative with the hood to create an air flow through the hood and to the exhaust duct; a fire barrier air filter mounted to the hood to receive and filter the air flow, the fire barrier air filter comprising a plurality of elongate extruded bodies in parallel alignment; each extruded body bound by first and second opposing concave surfaces and first and second baffle surfaces, the first and second baffle surfaces oriented transverse to the air flow; and at least one of the of the first and second concave surfaces oriented in facing opposition to a neighboring concave surface provided by a neighboring extruded body to form a cooperating pair of facing concave surfaces, the pair of facing concave surfaces defining a narrow longitudinal inlet gap, a narrow longitudinal outlet gap, and a longitudinal tubular chamber communicating therebetween. A kit providing at least a fire barrier air filter of the system and instructions for its installation is also described. A method of fire prevention using components of the system or kit is also described.
