Abstract:
A method of operation of a burner system includes introducing a fuel stream into a perforated flame holder, combusting the fuel stream, with a majority of the combustion occurring between an input face and an output face of the flame holder, and producing a heat output from the combustion of at least 1.5 kBTU/H/in 2 .

Abstract:
The invention describes a gas premix burner (100) comprising a porous combustion surface (120, 140, 142), on which when the burner (100) is in use combustion occurs after the premix gas has flown through it, a fiber based cloth (120) forming at least part of the porous combustion surface (120, 140, 142); and a perforated plate (110), a woven wire mesh or expanded metal sheet. The fiber based cloth (120) is supported by the perforated plate (110), woven wire mesh or expanded metal sheet. One or more zones (140, 142) of the porous combustion surface (120, 140, 142) is or are not formed by the fiber based cloth (120), but by another porous substrate. The one or more zones (140, 142) are along their full circumference surrounded by the fiber based cloth (120).

Abstract:
Die Erfindung betrifft eine Brennervorrichtung (100) zum Verbrennen eines Kraftstoff-Luft- Gemischs in einem Brennraum (126), der mindestens teilweise durch eine Brennraumhülse (106) definiert ist. Die Brennraumhülse (106) umfasst ein elektrisch leitfähiges Material. Weiterhin sind ein Befestigungselement (108) zur elektrisch isolierten Befestigung der Brennraumhülse (106) sowie eine Elektrode (114) vorgesehen. Eine elektrische Kontaktierung (116) der Brennraumhülse (106) ermöglicht eine Messung eines lonenstroms (130) im Brennraum (126) zwischen Brennraumhülse (106) und Elektrode (114).

The invention relates to a novel porous hydrogen burner for fitting in different types of furnace which require a precise control of the heat flux and, in particular, in vapour reforming furnaces for natural gas or naphtha.
Abstract:
A radiant burner (10) and optional heat exchanger (90) arrangement where the radiant burner (10) has a generally enclosed cavity (24) defined, at least in part, by fuel gas impermeable surroundings (12,14) and a lower surface (62) of fuel gas permeable burner element (60), wherein cavity (12) preferably has two opening (16a,16b) exposed to an oxidizer source. Sealingly coupled to openings (16a,16b) are mix tubes (50a,50b), each having respective first ends (52a,52b) and second ends (54a,54b), wherein first ends (52a,52b) occupy openings (16a, 16b) and second ends (54a, 54b) extend into and are exposed to cavity (12). Fuel gas injectors (48a,48b), which during use are in fluid communication with fuel gas (100), are positioned to introduce fuel gas into mix tubes (50a,50b). Pre-combustion gasses migrate to upper surface (64) and are available for ignition. A thermal fuel flow interrupt may be positioned between fuel gas (100) and gas injectors (48a,48b) to isolate the fuel gas in the event of an overheat malfunction. Because burner (60) functions as a radiant body, increased thermal transfer efficiency over the prior art can be achieved by exploiting this fact, such as by creating a dedicated heat exchanger arrangement (90) for containers (70) placed on or proximate to burner (60). Exposed surfaces (80,82,84) are established to exploit the relative slow velocity of heated combustion gasses, thereby increasing heat transfer flux into container (70).

Die Erfindung betrifft weiterhin ein Verfahren zum Bereitstellen eines homogenen Gemisches aus Brennstoff und Oxidationsmittel.
Abstract:
The present invention relates to a radiating gas burner having a burner nozzle in the shape of a metallic-felt porous body, wherein said body is made of a refractory heat-resistant alloy having a fully open variable-thickness volume porosity ranging from 90 to 98 %. The average size of the pores along the thickness of the burner nozzle ranges from 50 to 1000 mu m and decreases in the direction of the protection lid. Discrete fibres extend above the upper surface at a given angle relative to said lid. The metallic-felt porous body is mounted within a support housing made of a refractory material.
Abstract:
A gaseous fuel burner and method in which a high-firing rate (blue/non-surface) (9) zone is created between two lower firing rate (red/surface radiant) (3) combustion zones. The method of the invention can be achieved by selective perforation of porous sintered fiber mat burner surfaces to achieve improved burner performance and relatively low NOx emissions.
