20090291403 | METHOD AND APPARATUS TO DELIVER SOLID FUEL TO A COMBUSTION ZONE - An apparatus and method for consistently delivering solid fuel to the combustion zone of a furnace is disclosed. The method includes feeding the solid fuel into the material inlet of a rotating rotary air lock valve which may have slanted vanes and moving the fuel from the material inlet of the rotating rotary air lock valve to the material outlet of the rotating rotary air lock valve, and conveying the fuel and gas through a discharge conduit to a fuel feed receiver of a furnace burner having a combustion zone. | 11-26-2009 |
20110008739 | DETONATION WAVE ARRESTOR - An apparatus and system disclosed herein provides detonation wave arrestor including a detonation wave deflector and a burst element. The detonation wave arrestor disclosed herein attenuates and defects the propagation of a detonation wave characterized by a supersonic flame front propagation. The detonation wave arrestor provides deflection of detonation wave towards the burst element. The rupture of the burst element provides venting of hot gases remaining from the detonation, thus providing separation and attenuation of combusted gas residuals. The detonation wave arrestor disclosed herein may be used in a combustible fuel delivery system. | 01-13-2011 |
20110250554 | Demisting Flame Arrestor for an Electrolytic Hydrogen Generator - A demisting flame arrestor provides a border between an electrolytic reaction vessel and an intake manifold of an engine, and includes a composite material having hydrophilic zones and hydrophobic zones constructed to form multiple pathways for permitting gaseous flow. The hydrophilic zones promote trapping and condensation of water vapor and in the event of fire disperse flame into the multiple pathways to arrest the flame front. The hydrophobic zones repel condensed water to return the water to the reaction vessel through force of gravity. | 10-13-2011 |
20120189966 | DETONATION FLAME ARRESTOR INCLUDING A TRANSITION POINT/ATTENUATION MATRIX AND TORTUROUS PATH MEDIA - A detonation flame arrestor including an outer cylinder, an inner cylinder, transition point/attenuation matrix and tortuous path media. The inner cylinder is secured to a canister flange and positioned inside the outer cylinder secured to the canister flange, altogether forming a canister. The torturous path media is positioned in the canister between the inner cylinder and the outer cylinder to to provide turbulence and a large surface area which acts as a heat sink to extinguish a flame. Both the outer cylinder and the inner cylinder include a transition point/attenuation matrix which forms their respective cylindrical circumferences. Helical or parallel wire or rings create the transition point/attenuation matrix which attenuates and creates turbulence as the first stage of quenching a flame front. | 07-26-2012 |
20140030666 | FLASHBACK ARRESTOR - A flashback arrestor for use in gas cutting or welding equipment includes a porous body which defines a proximal end portion and a distal end portion and which has a plurality of pores. Each of the pores defines a pore size. The pore size is a function of a detonation cell size such that the pore size is increased to reduce a size of the sintered body. | 01-30-2014 |
20150300630 | PRESSURE-GAIN COMBUSTION APPARATUS AND METHOD - A pressure gain combustor comprises a detonation chamber, a pre-combustion chamber, an oxidant swirl generator, an expansion-deflection (E-D) nozzle, and an ignition source. The detonation chamber has an upstream intake end and a downstream discharge end, and is configured to allow a supersonic combustion event to propagate therethrough. The pre-combustion chamber has a downstream end in fluid communication with the detonation chamber intake end, an upstream end in communication with a fuel delivery pathway, and a circumferential perimeter between the upstream and downstream ends with an annular opening in communication with an annular oxidant delivery pathway. The oxidant swirl generator is located in the oxidant delivery pathway and comprises vanes configured to cause oxidant flowing past the vanes to flow tangentially into the pre-combustion chamber thereby creating a high swirl velocity zone around the annular opening and a low swirl velocity zone in a central portion of the pre-combustion chamber. The E-D nozzle is positioned in between the pre-combustion chamber and detonation chamber and provides a diffusive fluid pathway therebetween. The ignition source is in communication with the low swirl velocity zone of the pre-combustion chamber. This configuration is expected to provide a combustor with a relatively low total run-up DDT distance and time, thereby enabling high operating frequencies and corresponding high combustor performance. | 10-22-2015 |
20160067532 | FLAME ARRESTER - The flame arrester is optimized for installation within fuel containers. The flame arrester has an elongate, generally cylindrical skeletal frame having opposing first and second ends. The first end is configured as a mounting flange adapted for permanent, immovable installation within the tank or container and the second end may include a spring-loaded check valve. The frame is covered by a woven or nonwoven textile material, or alternatively, by a porous or foraminous sheet material. Fuel and vapors pass through the cylindrical textile wall, the porosity of the textile serving to prevent flame propagation through the textile material. The frame is formed of a flexible, fuel-impervious plastic material to allow the flame arrester to be bent or curved for installation within a curved tube. | 03-10-2016 |
20160123581 | BURNER NOZZLE, BURNER AND A SURFACE TREATMENT DEVICE - A burner nozzle is disclosed, comprising a nozzle body that includes a slit such that a line passage to the slit opens in an outlet face surface at the surface of the burner nozzle body. A plurality of channels is connected to the slit. A group of first channels is connected to a source of oxidizing substance, and a group of second channels is connected to a fuel source. Each of the first channels and second channels have a circumferential passage to the slit at a non-zero distance from the outlet face surface. Furthermore, each of the first channels and second channels is formed to output a directed tubular flow towards a side wall of the slit, or towards a circumferential passage in a side wall of the slit. A safe pre-mixed burner configuration is achieved. A burner and a surface treatment device incorporating the burner nozzle are also disclosed. | 05-05-2016 |
