    Abstract: A combustion burner 1 includes a fuel nozzle 2 that injects fuel gas prepared by mixing solid fuel and primary air, secondary air nozzles 3, 4 that inject secondary air from the outer periphery of the fuel nozzle 2, and a flame holder 5 that is arranged in an opening of the fuel nozzle 2. In the combustion burner 1, the flame holder 5 has a splitting shape that widens in the flow direction of the fuel gas. When seen in cross section along a direction in which the flame holder 5 widens, the cross section passing through the central axis of the fuel nozzle 2, a maximum distance h from the central axis of the fuel nozzle 2 to the widened end of the flame holder 5 and an inside diameter r of the opening 21 of the fuel nozzle 2 satisfy h/(r/2)

    Abstract: A burner tip, and method of manufacture, has a support layer with an external surface exposed to combustion reactions and an unexposed internal surface defining at least one a passage therethrough to deliver fuel and combustion gasses, and a thermal protective layer disposed on at least part of the unexposed surface of the burner tip support layer. The thermal protective layer 22 has from about 5% to about 40% of an inorganic adhesive, from about 45% to about 92% of a filler, and from about 1% to about 20% of one or more emissivity agents.

    Abstract: An air nozzle provided on the outer side of a fuel nozzle of a solid fuel burner is divided into a plurality of regions, and has means for regulating air flow rates in nozzles divided in the upper and lower direction. The nozzles (regions) are connected to only the nozzle wall and have obstacles in the circumferential direction, dividing the inside of the nozzle into a plurality of regions, and by changing air flow rates in the respective regions in the outermost peripheral air nozzle, a deviation in momentum is caused in the vertical direction of the burner, a flame forming position is changed, and a combustion gas temperature at the furnace outlet, temperatures of a heat transfer tube installed on the furnace wall surface and a fluid flowing in the heat transfer tube or temperatures of heat transfer tubes provided in the furnace and a flue on the downstream side and temperatures of fluids flowing in the heat transfer tubes are controlled to be constant.

    Abstract: The invention relates to a burner with a burner head and burner tubes (A, I, Z), arranged in the burner head, which are made of metal and are intended for feeding at least one fuel (K) and an oxidizing agent (O) into a reaction space. At least one of the burner tubes (I) is provided with a cladding (V) which is composed of a ceramic material and entirely or partially covers the inner or the outer surface of the burner tube so that hot gas corrosion and mechanical abrasion are avoided. In order to minimize the mechanical loads acting on the cladding, the ceramic cladding (V) is connected to the metallic burner tube (I) by means of a form-fitting connection.
