    摘要： A water tube boiler using jet flames is disclosed which is capable of achieving low CO-emission combustion without enlarging a size of a combustion chamber. The water tube boiler comprises a combustion chamber 1 in which jet flames are generated and rows 3a to 3e of water tubes inserted through the combustion chamber. The group of water tubes provides a portion thick with the water tubes and a portion empty of the water tubes in a cross-section perpendicular to the direction of the jet flames, and at least the space Sa as an empty portion continuously extends through said group of water tubes in the direction of the jet flames. In the space Sa as an "empty" portion provided between the rows 3b and 3d of water tubes, recirculating flows (shown by arrows) of a combustion gas are generated. The recirculating flows are entrained by the jet flames existing the portion "thick" with the water tubes. Consequently, rapid temperature decrease of the jet flames is prevented. This enables the jet flames to flow downstream while maintaining a CO oxidation promoting temperature of about 1,000 to 1,500.degree. C., thereby promoting CO oxidation reaction. Accordingly, residual CO of an exhaust gas is greatly reduced.

    摘要： A flat flame burner is disclosed having flow passages for admitting fuel and air to a burner tile. A structure for producing a rotational flow cooperates with a divergent burner tile in order to produce a radially-divergent flame with a very small axial component and a high degree of entrainment of inert combustion products in a furnace. A portion of the fuel is injected into the entrained furnace products, in order to suppress the rate of combustion, so as to produce an ultra low NOx flat flame burner. The present invention also permits greater versatility and improved operability over previous flat flame burners.

    摘要： A burner has a plate (21) with small openings (22) leading a first portion of the combustion air to mix with fuel and larger openings (24) for leading a second portion of the combustion air to mix with the burning fuel downstream of the position where the first portion of the air mixes with the fuel. The smaller openings (22) are sufficiently small for boundary layer effects to influence the ratio of the first portion to the second portion of the combustion air as the temperature of the air changes.
