摘要:
The patent application discloses a gas premix burner (100) comprising - a perforated plate, a woven wire mesh or expanded metal sheet; - a fiber based burner deck (130) placed on the perforated plate, woven wire mesh or expanded metal sheet; wherein the fiber based burner deck (130) has a same mass per unit of surface area over the full surface of the burner deck (130); - an ignition electrode (160) to ignite the gas premix burner, The fiber based burner deck (130) is thicker in at least part of the region where the ignition electrode (160) is located, than in at least some other areas of the fiber based burner deck (130). Burners of the invention show improved ignition characteristics.

The invention relates to a novel exchanger reactor intended to perform highly endothermic reactions, such as the steam reforming of natural gas or naphtha, using porous burners installed in situ.
摘要:
Un brûleur à gaz à fibres fusionnées (10) est constitué d'un corps de brûleur (12) doté d'une alimentation (14) d'un côté et d'un orifice (16) de l'autre côté. Avec des fibres discontinues d'un matériau déposé dans un moule de manière aléatoire, on crée une matrice de fibres (12) présentant la configuration générale de l'orifice du brûleur. Une fois les fibres déposées dans le moule à une profondeur d'environ 0,5 pouce, on les porte à quelques 1200 °C pendant environ deux heures, ce qui les soude. On peut alors mettre cette matrice de fibres en place dans l'orifice du brûleur.
摘要:
An object of the present disclosure is to provide a pre-mixed burner capable of preventing a backfire, improving flame stability, and responding to various combustion loads. To attain the object, the present disclosure is implemented by including a flame hole member made of a foam body which is made from a plurality of metal alloys through a sintering process and in which an air hole being a space between struts configuring a framework is formed, and configured to form a flame by allowing a mixed gas of gas and air to be sprayed through the air hole, a flame hole member fixing plate configured to fixedly couple the flame hole member to a burner main body, and a distributing plate provided in front of the flame hole member and at which a plurality of distributing holes are formed so as to uniformly supply the mixed gas to the flame hole member.
摘要:
Die vorliegende Erfindung betrifft einen Strahlungsbrenner für gasförmige Brennstoffe mit einer Gaszufuhr und einer Brenneroberfläche (1), die für den Brennstoff durchlässig ist und an der der Brennstoff abbrennt, wobei die Brenneroberfläche (1) heterogen ausgebildet ist und mindestens zwei unterschiedliche Oberflächenbereiche aufweist, wobei ein oder mehrere erste Oberflächenbereiche (3) durchlässig für den Brennstoff sind, während ein oder mehrere zweite Oberflächenbereiche (2) undurchlässig für den Brennstoff sind. Darüber hinaus betrifft die vorliegende Erfindung ein Verfahren zur Herstellung eines Strahlungsbrenners für gasförmige Brennstoffe mit einer entsprechend gekennzeichneten Brenneroberfläche.
摘要:
A multilayer radiant burner which has exceptionally low NO X emissions can be operated over a broad turndown range. The burner is a three-dimensional matrix of spaced apart emissive layers. It comprises a burner tray (1), seal frames (3) made from alumina felt, a supportive layer of perforated metal (4), a porous distributive layer of twilled weave Kanthal wire (5), a steel frame (6), and an emitter (8) made of Kanthal AF, based on four ceramic legs (7). A quartz tube (9) is installed on the top of the burner for separation of the ambient air from waste gases. Such high intensity burners, e.g. 1,500,000 BTU/h·ft 2 , may be used in water heaters or boilers or in a thermophotovoltaic apparatus which produces both electric energy and heated water.
摘要:
A radiant burner and method are disclosed. The radiant burner is for treating an effluent gas stream from a manufacturing processing tool and comprises: a plurality of treatment chambers, each treatment chamber having an effluent stream inlet for supplying a respective portion of said effluent gas stream to that treatment chamber for treatment therewithin. In this way, multiple treatment chambers may be provided, each of which treats part of the effluent stream. Accordingly, the number of treatment chambers can be selected to match the flow rate of the effluent gas stream from any particular processing tool. This provides an architecture which is reliably scalable to suit the needs of any effluent gas stream flow rate.
