    摘要： A burner is disclosed for generating flame and heat. The burner includes a first stage, a second stage downstream of the first stage, a third stage downstream of the first and second stages, and a fourth stage downstream of the first, second, and third stages. The first stage comprises a first innermost air chamber and a first mixing chamber for air and fuel, wherein the first stage includes separate conduits for air and fuel, and wherein the air and fuel begin to mix in the first mixing chamber during use to form an air/fuel mixture. The second stage comprises a second mixing chamber which comprises a deflection plate to force the air/fuel mixture outward from the centerline. The third stage comprises a combustion zone. The combustion zone includes a swirl generator. The swirl generator has an inner diameter greater than an outer diameter of the deflection plate. The swirl generator produces a swirl, whirl, vortex, or the like in the flame during operation.

    摘要： A combustion apparatus includes a combustion chamber having multiple combustion zones. A first wind box is in communication with the first combustion zone to feed the fuel to be fed into the combustion chamber for initial combustion of the fuel within the first combustion zone. A second wind box has a reburner in communication with the second combustion zone. The reburner is configured to feed fuel, a reagent and a first portion of the flue gas to be recycled to the second combustion zone into the second combustion zone to reduce nitrogen oxide emissions of the apparatus. A third wind box is in communication with the third combustion zone to feed air to the third combustion zone to complete the combustion process.

    摘要： 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)
