Abstract: A burner cleaning device for cleaning burners, in particular for gas turbine burners, with a fuel nozzle and a fuel supply line is disclosed. The burner cleaning device has a rinsing head provided with an opening that is placed on a fuel nozzle of the burner and that enables a rinsing fluid to be supplied to or evacuated from the nozzle, and/or a fluid line that is connected to the fuel supply line of the burner and that enables the rinsing fluid to be supplied to or evacuated from the fuel supply line, and a pump. The pump, the rinsing head and/or the fluid line are fluidically interconnected such that they form a flow path through which the rinsing fluid sequentially flows.

Abstract: A method and apparatus for vaporizing liquid fuel. The apparatus includes at least one capillary flow passage, the at least one capillary flow passage having an inlet end and an outlet end; a fluid control valve for placing the inlet end of the at least one capillary flow passage in fluid communication with the liquid fuel source and introducing the liquid fuel in a substantially liquid state; a heat source arranged along the at least one capillary flow passage, the heat source operable to heat the liquid fuel in the at least one capillary flow passage to a level sufficient to change at least a portion thereof from the liquid state to a vapor state and deliver a stream of substantially vaporized fuel from the outlet end of the at least one capillary flow passage; and means for cleaning deposits formed during operation of the apparatus. The flow passage can be a capillary tube heated by a resistance heater or a section of a tube heated by passing electrical energy therethrough. The liquid fuel can be supplied to the flow passage at any desired pressure depending on the required mass flow rate for the application. The vaporized fuel can be mixed with air to form an aerosol having a mean droplet size of 25 μm or less to minimize ignition energy of the fuel-air mixture, promote fuel flow in an air stream, and combust the liquid fuel efficiently and cleanly.

Abstract: A device for cleaning a tip of a furnace burner including a support tube of axis X intended to pass through the burner and where the support tube includes a metal cable connected at one of its ends to a scraper and at the other end to a system for setting and maintaining the position of the scraper, where the scraper is articulated on the support tube between a first position aligned with the axis X in the continuation of the support tube and a second position perpendicular to the axis X, where the scraper has a chamfered part on its profile and where the support tube is connected to a rotation means for rotating the entire whole device in rotation. It can be set in place and manipulated from the rear of the burner, thereby ensuring a good level of safety for interventions, such that a rotational and/or translational movement about the tip of the burner allows the concretions to be cleaned off effectively whatever their nature (shape, hardness, etc.) and their position.
