A vaporizer-burner using liquid fuel such as oil, in which the oil conducted to the combustion chamber is vaporized before being ignited and in which the air required for combustion has been conducted to the combustion chamber along a separate duct. The problem in this type of vaporizer-burners of prior art is the continuous vacuum prevailing in the combustion chamber during operation, which renders the flame unstable and sensitive to changes in ambient conditions, such as wind squalls. With the vaporizer-burner of the invention, the problem has been solved in that the air supply duct has been divided into two parts, one directing air to the oil vaporizing process and the other to the combustion process, and that the supply proportion of said so-called primary and secondary airs can be adjusted with the aid of a turnable flap placed in the duct.
