摘要： In a burner of construction having a primary nozzle (4), a secondary nozzle (8) and a tertiary nozzle (9), a partition wall (1, 2) partitioning the secondary nozzle (8) and the tertiary nozzle (9) and having a flow path change member (3) provided thereon, the partition wall (2) is formed so as to be movable in parallel to the burner axis to control jetting speeds and flow rates of secondary air and tertiary air, whereby it is possible to cool the burner constituent members while reducing NOx. The partition wall (1, 2) is composed of a fixed wall (1) and a movable wall (2). The burner comprises a bypass passage (16, 19) through which tertiary air in the tertiary nozzle (9) bypasses the tertiary nozzle to flow into the secondary nozzle (8) or the primary nozzle (4).

摘要： The invention provides a boiler provided with low cost means which can reduce a concentration of CO, an unburned matter, an attached ash and the like near a side wall and maintain a combustion state well with a simple structure. In a boiler having a combustion chamber (13) formed by front (14a) and rear walls (14b)(burner walls) provided with a plural stages of burners (2,3 and 4) on at least one of them and opposing to each other, and side walls (1a and 1b) crossing to said burner walls (14a and 14b), a gas port (6) containing no fuel for making a pressure of a gas near said side walls (1a and 1b) within said combustion chamber (13) higher than a pressure of a gas at a center portion of said combustion chamber (13) is provided between an outermost burner and the side walls (1a and 1b) within a range of a height of said burner stages (2,3 and 4). A combustion gas (16) can not come close to the side walls (1a and 1b) due to the jet (18) of the gas.
摘要翻译： 本发明提供了一种具有低成本装置的锅炉，其能够在侧壁附近降低CO浓度，未燃烧物质，附着灰分等，并且以简单的结构保持良好的燃烧状态。 在具有由前面（14a）和后壁（14b）（燃烧器壁）形成的燃烧室（13）的锅炉中，所述燃烧室在其至少一个上设置有多级燃烧器（2,3和4）并与每个燃烧室 其他和与所述燃烧器壁（14a和14b）相交的侧壁（1a和1b），不包含用于在所述燃烧室内的所述侧壁（1a和1b）附近形成气体的燃料的气体端口（6） 在所述燃烧器级（2,3）的高度的范围内，在最外侧的燃烧器与所述侧壁（1a，1b）之间设置高于所述燃烧室（13）的中央部的气体的压力 和4）。 由于气体的喷射（18），燃烧气体（16）不能靠近侧壁（1a和1b）。
