Burner Device

Abstract

A burner device for operation with a fuel that is liquid at room temperature, especially a vegetable oil, including an evaporator system for evaporating the liquid fuel, and a nozzle for ejecting and for igniting the evaporated fuel under the effect of flame. The burner also includes a heat conducting sheet which at least partially surrounds the evaporator system.

       11 . A burner device for operation with a fuel that is liquid at room temperature, especially a vegetable oil, the burner device comprising:
 an evaporation system for evaporation of the liquid fuel;   a nozzle in fluid communication with the evaporation system for expelling and for igniting the evaporated fuel;   a baffle plate disposed in fluid communication with the. nozzle for forming a combustion space intermediate the baffle plate and the nozzle;   a fuel tray disposed in fluid communication with the nozzle, and a heat conducting sheet disposed in at least a partial surrounding relationship with the evaporation system, the heat conducting sheet having at least one air supply opening formed therein for delivering combustion air to the burner device.   
   
   
       12 . The burner device according to  claim 11  wherein the heat conducting sheet includes a first air supply opening formed therein for supplying air to a combustion space formed below the baffle plate and a second air supply opening formed therein for supplying air to a fuel located in the fuel tray. 
   
   
       13 . The burner device according to  claim 11  wherein the heat conducting sheet is formed with a first wall portion and a second wall portion spaced from the first wall portion. 
   
   
       14 . The burner device according to  claim 13  wherein the first and second wall portions are curved and second wall portion is spaced radially away from the first wall portion defining an annular air gap therebetween. 
   
   
       15 . The burner device according to  claim 14  wherein the annular gap is in fluid communication, using the air supply openings in the first wall portion, with an inner chamber defined within the curvature of the first wall portion. 
   
   
       16 . The burner device according to  claim 14  wherein the annular gap formed by the first and second wall portions of the heat conducting sheet forms an air duct. 
   
   
       17 . The burner device according to  claim 14  wherein the annular gap formed by the first and second wall portions of the heat conducting sheet is closed at one end of the first and second wall portions. 
   
   
       18 . The burner device according to  claim 13  wherein the heat conducting sheet is formed with at least one cutout on a face of at least one of the first wall portion and the second wall portion.
