摘要:
An apparatus and process for vaporizing and, optionally, igniting a liquid fuel, preferably, a distillate fuel. The apparatus includes the following components: a heat-conductive reticulated screen positioned within a chamber; a first inlet path into the chamber for delivering a liquid fuel onto the screen; a second inlet path into the chamber for contacting an oxidant with the screen and fuel; a means for heating the screen to a temperature sufficient to vaporize and, optionally, ignite the liquid fuel; and a recuperator in fluid communication with the chamber for transferring heat from the chamber to the second inlet path. The apparatus is suitably employed in compact and portable oxidation reactors, for example, in external combustion engines, catalytic partial oxidation reformers, and hybrid combustors operating in flame and/or catalytic modes.

The present invention is directed to a process for the clean and convenient combustion of high viscosity liquid fuels, such as glycerol, as well as an apparatus useful for carrying such processes. In certain embodiments, the invention provides a process for glycerol combustion comprising providing a combustion apparatus (10) with a glycerol combustion chamber (185) that facilitates reflective heating, pre-heating the glycerol combustion chamber, atomizing the reduced viscosity glycerol, and combining the atomized glycerol with air in the glycerol combustion chamber to thereby completely combust the glycerol. In one embodiment, such as when using a pressure-atomizing nozzle (200), the inventive method may further comprise treating the glycerol to reduce the glycerol viscosity.

The invention relates to a method for controlling an evaporator burner, having an electrically heatable evaporator chamber, to which the heating oil to be burned is supplied, and having a fan for feeding the combustion air. According to the invention, an actual evaporator chamber temperature value TVDKIst is adjusted to a target evaporator chamber temperature value TVDKSoll after the burner is started, namely by varying the amount of air supplied to the burner, which is carried out by means of controlling a rotational speed D of the fan according to a function D = f(TVDKIst). Ideal evaporation of the heating oil is achieved by the control according to the invention. This prevents carbon build-up residue of the heating oil in the evaporator chamber. Furthermore, trouble-free burner operation is achieved over a long period of use by means of the invention, according to which the imission threshold values are adhered to.
摘要:
Die Erfindung betrifft einen Porenbrenner (1) mit einem Gehäuse (2), welches einen Einlass (3) für ein Brennstoff-Luftgemisch (4) und einen Auslass (5) für das im Brenner entstehende Abgasgemisch (6) aufweist, wobei im Gehäuse (2) in Strömungsrichtung der Prozessgase ein Zündraum (7) mit einer Zündeinrichtung (8) und daran anschließend ein Porenkörper (9) angeordnet sind. Erfindungsgemäß weist der Zündraum (7) einlassseitig ein Stabilisatorelement (10) auf, welches den Einlassquerschnitt verringert und die Strömung des Brennstoff-Luftgemisches im Wesentlichen senkrecht auf den Einlassquerschnitt des Porenkörpers (9) ausrichtet, wobei der Porenbrenner (1) eine Einrichtung (11) zur Regelung des Massenstroms des Brennstoff-Luftgemisches (4) aufweist, welche zur Verlagerung der Verbrennungszone aus dem Zündraum (7) in den Porenkörper (9) dient.

The invention concerns a pre-vaporizing and pre-mixing burner for liquid fuels which has a fuel feed line (56), a pump which pressurizes the fuel in the feed line, a mixing region (123) and a fuel valve (119) which opens out into the mixing region and by means of which the fuel is atomized and fed to the air for combustion (127). According to the invention, the fuel is vaporized in an optimum manner in that the fuel valve opens automatically as from a given fuel pressure, and a heating device (128) is associated with the fuel valve.
摘要:
Le combustible et l'air sont réunis dans une chambre de mélange (1) cylindrique dans laquelle une dépression peut être créee. L'air est introduit dans la chambre de mélange (1) via des ouvertures latérales pratiquées dans le logement (2) de cette dernière, depuis une chambre d'air (6) circonvoisine de la chambre de mélange (1). Il se forme dans cette dernière un cyclone et le combustible pénètre dans ladite chambre (1) dans l'axe médian longitudinal de cette dernière. Le logement (2) de la chambre de mélange (1) peut être chauffé par au moins un corps de chauffe à résistance électrique (3). La longueur de la chambre de mélange (1) est supérieure à son diamètre, et les ouvertures latérales s'étendent au moins approximativement sur toute la longueur du logement (2) et sont des fentes (5) ou des alésages (4) qui débouchent tangentiellement dans la chambre de mélange (1).
