A burner for a metal-melting furnace can releasably receive a tapered plug in sealing engagement with an access passage aligned with an air passage. The burner may be configured to extend through a wall of the metal-melting furnace so that the air passage is through a front face within the furnace and so that the access passage is through a rear face outside of the furnace. The access passage may be aligned with the air passage to permit a rigid structure to be passed through the burner from outside the furnace to dislodge build-up of solidified metal from the air passage. The tapered plug may be moveable between a sealing configuration of being received in a seat to seal the access passage during burner operation and a cleaning configuration of being removed from the seat to expose the access passage for insertion of the rigid structure.

A system comprises a gas turbine engine including a compressor, combustor, gas turbine, the combustor including a plurality of late lean fuel injectors; and wash system configured to be attached to and in fluid communication with the a plurality of late lean fuel injectors of the combustor. The wash system includes a water source supplying water; a first fluid source supplying a first fluid; a mixing chamber in communication with the water source and first fluid source; a water pump to pump water to the mixing chamber; a first fluid pump to pump the first fluid to the mixing chamber; a fluid line in fluid communication with the mixing chamber and at least one of the plurality of late lean fuel injectors so fluid from the mixing chamber is injected into the combustor at late lean fuel injectors. The wash system is operated with the gas turbine engine off-line.

A burner assembly system is disposed in a rear side, i.e. back side, of a deep fryer. The burner assembly system includes an aperture disposed in a side of a bottom portion at the rear of a fryer cabinet of the controlled deep fryer. A burner at the rear of the fryer cabinet is coupled to the aperture and is adapted to receive fuel that enters through the aperture. An ignition assembly is disposed within the burner and ignites the received fuel. A flue is disposed at the rear of and within the fryer cabinet and receives combustion gases and heat from the burner created by the ignition of fuel. A heat exchanger is disposed within the flue at the rear of the fryer cabinet and is heated by heat conveyed through the flue from the ignition of fuel in the burner.

A device for cleaning a tip of a furnace burner including a support tube of axis X intended to pass through the burner to have the burner passing through it 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, in that the scraper is articulated to 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, in that the scraper has a chamfered part on its profile and in that the support tube is connected to a rotation means for setting 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.
