The invention concerns a pre-vaporizing and pre-mixing burner for liquid fuels which has a fuel feed line (56), a pump which pressurizes the fuel in the feed line, a mixing region (123) and a fuel valve (119) which opens out into the mixing region and by means of which the fuel is atomized and fed t

The invention concerns a pre-vaporizing and pre-mixing burner for liquid fuels which has a fuel feed line (56), a pump which pressurizes the fuel in the feed line, a mixing region (123) and a fuel valve (119) which opens out into the mixing region and by means of which the fuel is atomized and fed to the air for combustion (127). According to the invention, the fuel is vaporized in an optimum manner in that the fuel valve opens automatically as from a given fuel pressure, and a heating device (128) is associated with the fuel valve.

1. A prevaporizing and premixing burner for liquid fuels, comprising:at least one fuel heater for heating the liquid fuel; means for increasing the pressure of the liquid fuel; a nozzle for atomizing and vaporizing the fuel and for mixing the fuel with combustion air, wherein at least a portion of the vaporized fuel condenses, creating thereby one of: a colloid-dispersed fuel-air mixture, a molecular-dispersed fuel-air mixture, and a colloid-dispersed and molecular-dispersed fuel-air mixture; and a hydraulic system with a blockable fuel valve which, during heating and prior to combustion, and during cooling following combustion, maintains the liquid fuel at a pressure increased above ambient pressure and excludes air, and which keeps the liquid fuel under pressure during heating, during combustion and during cooling, wherein said blockable fuel valve has a tappet, wherein the closing force of said tappet is greater during the burning start and switch-off phases than the force created by the difference between the forward and return flow pressure, which acts in the opposing direction of said closing force on said valve tappet.
