    摘要： The invention relates to a pulverized coal burner for a steam generator. The pulverized coal burner has a fuel duct, through which pulverized coal is conveyed with the aid of a carrier gas. The pulverized coal emerges together with the carrier gas at a fuel duct outlet. The pulverized coal burner furthermore has at least one core duct and at least one secondary duct. Air or oxygen flows through the core duct and the secondary duct, emerging at the core duct outlet and at the secondary duct outlet. The core duct outlet, the secondary duct outlet and the fuel duct outlet together form a burner outlet. The pulverized coal burner has at least one plasma ignition torch embodied integrally with the pulverized coal burner. The outlet of the at least one plasma ignition torch is arranged in the plane of the burner outlet or offset downstream in relation to the direction of flow of the pulverized coal. The plasma flame produced by the plasma ignition torch is thus located outside the fuel duct.

    摘要： A gas burner for low NOx gas furnaces is disclosed with improved flame carryover for igniting one or more adjacent burners. The burner includes a burner tube that receives a mixture of fuel and air. The burner tube is coupled to an outlet. The outlet includes a primary outlet opening which is in communication with at least one transverse slot for communicating a flame to at least one adjacent burner. The primary outlet opening may be elliptical and the outlet further may also include a concave outer face through which the primary outlet opening extends. The at least one slot may include a pair of oppositely directed transverse slots extending outward from the primary outlet opening along a semi-minor axis of the primary outlet opening.

    摘要： A grilling appliance includes first and second fuel delivery ports extending from a grill housing, a first burner element selectively connected to one of the first and second fuel delivery ports to define a single-burner condition, a second burner element selectively connected to the other of the first and second fuel delivery ports to define, with the first burner element, a twin-burner condition, an elongated burner element having two fuel inlets selectively connected to the first and second fuel delivery ports to define, when the first and second burner elements are removed from the first and second fuel delivery ports and a large-burner condition. At least one ignitor is in communication with the first burner element in the single-burner condition, the first and second burner elements in the twin-burner condition and the elongated burner element in the large-burner condition.
