Abstract

Gaseous fuels derived from combustion of wood are used without intermediate refrigeration, to utilise entrained or volatile tars which otherwise tend to choke any intermediate filters. Used esp. for fuels for motors, partic. for vehicles.

Description

La présente invention concerne les gazogènes employant le bois comme combustible et destinés à l'alimentation des moteurs, plus spécialement de tous véhicules.The present invention relates to gas generators using wood as fuel and intended for powering engines, more particularly all vehicles.

Dans l'état actuel des réalisations, il apparaît que les foyers des gazogènes fonctionnant au bois ne sont pas conçus pour éviter des productions importantes de goudron qui vient perturber le fonctionnement des moteurs et des filtres chargés de son élimination.In the current state of the art, it appears that the fireplaces of gas generators operating with wood are not designed to avoid significant production of tar which disturbs the operation of the engines and filters responsible for its elimination.

La présente invention se réfère, tout d'abord, à la production de gaz qui, à la sortie du générateur, ne contiennent plus que des poussières de goudron facilement retenues par des éléments filtrants disposés contre le générateur; ces éléments étant garnis de laine de verre ou de tout autre matériau filtrant et incombustible.The present invention refers, first of all, to the production of gases which, at the outlet of the generator, no longer contain anything but tar dust easily retained by filter elements placed against the generator; these elements being lined with glass wool or any other non-combustible filtering material.

L'objet de la présente invention vise à simplifier la construction et le montage des gazogènes et à fournir, aux moteurs, un gaz pur, utilisé à chaud et enrichi de l'hydrogène qu'il contient et qui provient du combustible. La simplification est concrétisée par la suppression de l'appareil de réfrigération des gaz et de toutes les tubulures généralement utilisées entre générateur et appareil de réfrigération , réfrigérateur et filtre. De plus, il y a diminution importante'de la capacité des éléments filtrants.The object of the present invention is to simplify the construction and assembly of the gasifiers and to supply the engines with a pure gas, used hot and enriched with the hydrogen which it contains and which comes from the fuel. The simplification is concretized by the elimination of the gas refrigeration appliance and all the pipes generally used between generator and refrigeration appliance, refrigerator and filter. In addition, there is a significant decrease in the capacity of the filter elements.

Les gaz sont conduits au moteur par le circuit suivant, très raccourci: générateur - éléments filtrants - mélangeur du moteur.The gases are led to the engine by the following circuit, very shortened: generator - filter elements - engine mixer.

La présente invention est applicable à tous moteurs de tous véhicules, ou moteurs fixes, fonctionnant au gazogène à bois. The present invention is applicable to all engines of all vehicles, or stationary engines, operating with wood gasifier.
