Abstract
A burner for the formation and combustion of an ignitable mixture of liquid uel and combustion air, which includes a closed combustion chamber for the infeed of the fuel with porous walls permeable to the fuel. The combustion chamber is arranged within a flow chamber which is streamed through by preheated combustion air flowing towards the combustion zone.
Claims7
In a burner for the formation and combustion of an ignitable mixture of a liquid fuel and combustion air;
- said burner having an axis, a fuel chamber fillable with said fuel having porous side walls permeable to said fuel for the through-passage of said fuel and a non-perforated closure plate;
- and a combustion chamber, said combustion chamber including a flow chamber providing for the inlet of combustion air at one end, means for heating said air, and an outlet for heated combustion air at the opposite end of said flow chamber communicating with the interior of said combustion chamber to form a combustion zone;
- and means for axially displacing said fuel chamber into and out of said combustion chamber so as to form an advanced and a retracted position, respectively;
- said porous side walls of the fuel chamber being selectively communicable with the interior of said combustion chamber in response to the axial position of said fuel chamber in said combustion chamber so as to facilitate passage of fuel through said porous side walls into said combustion chamber in said advanced position of said fuel chamber into said combustion chamber for the switching on said burner and to prevent passage of fuel through said porous side walls in said retracted position of said fuel chamber from said combustion chamber for switching off said burner.

In a burner for the formation and combustion of an ignitable mixture of a liquid fuel and combustion air;
- said burner having an axis a fuel chamber fillable with said fuel for the infeed of fuel, said fuel chamber including porous side walls permeable to said fuel and a non-perforated closure plate;, a combustion chamber including a flow chamber providing for the inlet of combustion air at one end, means for heating said air, and an outlet for heated combustion air at the opposite end of said flow chamber communicating with the interior of said combustion chamber to form a combustion zone;
- and said fuel chamber being axially movable into and out of said combustion chamber so as to form an advanced and a retracted position, respectively, so as to facilitate passage of fuel through said porous side walls into said combustion chamber in said advanced position of said fuel chamber into said combustion chamber and to prevent passage of fuel through said porous side walls in said retracted position of said fuel chamber from said combustion chamber;
- hydraulic means for displacing said fuel chamber within said combustion chamber in opposition to a counter force, said hydraulic means comprising a hydraulic cylinder guiding said fuel chamber, said hydraulic cylinder including a fuel inlet for the introduction of fuel as a hydraulic operating medium and a hydraulic piston including fuel conduit leading from the interior of said hydraulic cylinder for conveying fuel to the interior of said fuel chamber;
- and a discharge means for said fuel extending from said fuel chamber through the inner space of said hydraulic cylinder;
- said hydraulic piston slidably arranged within said hydraulic cylinder, said fuel chamber being fastened to said piston, the end surface of said piston remote from the fuel chamber adjoining the fuel-filled inner space of said hydraulic cylinder, said discharge means being fixedly connected with said hydraulic cylinder and projecting into a recess in said hydraulic piston slidingly movable on said discharge means.
