Abstract

Verfahren und Vorrichtung zum Verbrennen flüssiger und/oder fester Brennstoffe, insbesondere Kohle oder dergl., in pulverisierter Form, wobei letztere trocken oder mit einer Trägerflüssigkeit, wie Wasser und/oder Öl, vermischt als Emulsion zusammen mit dem Brennstoff unter Ausbildung eines sich etwa konisch öffnenden Sprühkegels in einen Verbrennungsraum (16) eingeleitet werden und dieser Sprühkegel durch eine äußere, ge­ gebenenfalls rotierende Luftströmung begrenzt wird. Zur Ausbildung feinster Brennstoffpartikel unmittelbar hinter dem Brennstoff-Einlaß ist dieser durch eine zentrale, von einer umlaufenden Schneide (40) be­ grenzte Öffnung (10) gebildet. Ferner ist dieser Öffnung mindestens eine etwa radial gerichtete Luft­ eintrittsöffnung (42) zugeordnet, und zwar an der dem Verbrennungsraum (16) abgewandten Seite. Method and device for burning liquid and / or solid fuels, especially coal or the like, in powdered form, the latter dry or with a carrier liquid, such as water and / or Oil mixed as an emulsion with the fuel with the formation of an approximately conical opening Spray cone introduced into a combustion chamber (16) be and this spray cone by an outer, ge possibly rotating air flow is limited. For the formation of the finest fuel particles immediately behind the fuel inlet is through a central, be from a circumferential cutting edge (40) limited opening (10) is formed. Furthermore, this is Opening at least one approximately radially directed air assigned entry opening (42), namely at the side facing away from the combustion chamber (16).
