Abstract

A blower burner is provided for a boiler heated with fluid fuels with a blower casing, which incorporates on one side the blower with the attached drive motor and where the fire tube of the burner comes out on the other side. The motor and the fire tube form protruding parts on opposite sides of the blower housing. The rear side of the fire tube protrudes beyond the side of the casing disposed toward the drive motor and the rear side of the fire tube protrudes into a cover extension attachment of the blower casing. The burner is provided with a pressure controller, where the air pressure inside of the fire tube element is measured by the input sensor signal and where the blower speed is the variable controlled by the pressure controller. Furthermore, a sound absorbing means is provided for the blower burner.
