EVAPORATING BURNER, METHOD FOR ITS CLEANING AND CONTROL OF FUEL FEED TO IT Russian patent published in 2006 - IPC F23D5/18 

FIELD: evaporating burner used, for example, in automobile heating elements.

SUBSTANCE: the evaporating burner has an evaporative medium for supply of fuel vapors to the combustion chamber, the first heating device containing at least one element of hot-bulb ignition located at least by its heating area in the combustion chamber for ignition of fuel vapors being in the combustion chamber, the second heating device containing at least one heating element for evaporation, for influence on the evaporation characteristics of the evaporative medium, the evaporative medium is provided on the evaporative medium carrier on its one side facing the combustion chamber, at least one heating element for evaporation is positioned on the side of the evaporative medium carrier opposite the evaporative medium. The evaporating burner is provided with a system of fuel feed ducts for supply of liquid fuel to the evaporative medium, which has at least one circular area of ducts and/or at least one radial zone of the duct outgoing essentially radially from the fuel feed duct, in the evaporative medium and/or in the carrier of the evaporative medium. At least one heating element for evaporation and an evaporative medium are provided on the evaporative medium carrier made of a ceramic material. The evaporative medium has a porous material preferably positioned in several layers. The evaporating burner has a cleaning system for removal of depositions formed in the area of the combustion chamber at burning. The cleaning system has a heating system that provides for producing of a temperature in the area of the combustion chamber lying in the range of temperature of depositions burning or above it. The evaporating burner is provided with a control unit for control of the heating power at least of one heating element, the control module controls the heating power and/or the required heating power of the heating element, and on the basis of the control result identifies the presence of fuel evaporation.

EFFECT: provided quick reburning of the working phase with a high heating power.
