    • PURPOSE:To eliminate a replacement of nozzle even if fuel is converted and to keep a stable superior combustion by a method wherein a nozzle through which a maximum flow rate of fuel can be flowed and an air separator plate for use in separating the primary and secondary air are arranged. CONSTITUTION:All kinds of fuel are flowed out of a nozzle 3 through which a maximum flow rate of fuel can be discharged. The air is divided into the primary and secondary air by an air separator plate 17 and flows out of the primary air separation port 17a and the secondary air separation port 17b. The fuel and the primary air are injected out of the burner flame port 5a, the secondary air is injected out of the secondary air port 5b so as to perform a combustion. Thereby, it is possible to keep a constant primary air ratio and at the same time it is possible to perform a combustion with the same nozzle whatever the fuel is applied, resulting in that a poor combustion may not be occured, a replacement of nozzle is not required and a troublesome operation may be eliminated.
    • 目的:为了消除喷嘴的更换,即使燃料转化,并且通过其中可以流动最大燃料流量的喷嘴和用于分离一次和二次的空气分离器板的方法来保持稳定的优异燃烧 布置空气。 构成:各种燃料从喷嘴3流出,燃料的最大流量可通过喷嘴3排出。 空气通过空气分离器板17分成一次空气和二次空气,并从一次空气分离口17a和二次空气分离口17b流出。 燃料和一次空气从燃烧器火焰口5a喷射出来,二次空气从二次空气口5b喷射出来,进行燃烧。 因此,可以保持恒定的一次空气比,并且同时可以在施加燃料的情况下用相同的喷嘴进行燃烧,导致不能发生不良燃烧,喷嘴的更换是 不需要,并且可以消除麻烦的操作。

    • PURPOSE:To uniform the thermal absorption in a furnace and make it possible to reliably control the combustion state of each of burners, by providing a flow rate controller which regulates the amount of air supplied to each burner corresponding to each mill. CONSTITUTION:Coal is fed to a mill 5 by a coal feeder 3 while being regulated in the flow rate. The coal ground in the mill 5 is supplied to a multiplicity of burner 7 through pulverized-coal pipes 6 and burnt therein. On the other hand, the air for combustion is divided into a primary air 11 and a secondary air 12. The secondary air 12 is heated by a heater 13 and then injected into the furnace from wind boxes 22 through ducts 20. On the other hand, the primary air 11 is heated by the heater 13 and supplied being boosted up by a primary air fan 10. Dampers 15, 18, 17, 21 are provided on air supply lines, respectively, thereby allowing an individual regulation of the flow rate of the primary and secondary air with respect to the burner group for each mill 5, in addition to an overall flow rate regulation.
    • 目的:为了使炉中的热吸收均匀化,通过提供一种流量控制器,可以可靠地控制每个燃烧器的燃烧状态,该流量控制器调节对应于每个轧机的每个燃烧器供应的空气量。 规定:采煤机3供给煤粉5,同时以流量调节。 研磨机5中的煤粉通过粉煤管6供给多个燃烧器7并在其中燃烧。 另一方面,用于燃烧的空气被分成一次空气11和二次空气12.二次空气12由加热器13加热,然后通过管道20从风箱22注入炉中。另一方面 一次空气11由加热器13加热,并被一次空气风扇10提升。阻尼器15,18,17,21分别设置在供气管线上,从而允许单独调节 除了总体流量调节之外,相对于每个磨机5的燃烧器组的一次和二次空气。

    • PURPOSE:To prevent production of NOX, by a method wherein the air fed to a fluidized-bed combustion furnace is divided into a primary air and a secondary air. CONSTITUTION:A furnace is provided with a first flow meter 12 for measuring the flow rate of a primary air, a second flow meter 14 for measuring the flow rate of a secondary air, an oxygen concentration meter 16 for measuring oxygen concentration in exhaust gas, and a computing part 17 which, based on output signals from the flow meters 12 and 14, and the oxygen concentration meter 16, computes an xygen concentration condition on a fludizied bed surface 18. A first regulating part 19 outputs a control signal which regulates the flow rate of a primary air, based on a deviation between an oxygen concentration condition outputted from the computing part 17 and a previously set oxygen concentration condition on the fluidized bed surface 18. A second regulating part 20 outputs a control signal which controls the flow rate of a secondary air so that an output signal from the oxygen concentration meter 16 attains a previously set value. This prevents production of NOX.
    • 目的:为了防止生产NOX,通过将进料到流化床燃烧炉的空气分成一次空气和二次空气的方法。 构成:炉具有用于测量一次空气流量的第一流量计12,用于测量二次空气流量的第二流量计14,用于测量废气中氧浓度的氧浓度计16, 以及基于来自流量计12和14的输出信号和氧浓度计16的计算部分17计算浊化床表面18上的xygen浓度条件。第一调节部分19输出控制信号, 基于从计算部17输出的氧浓度条件与流化床表面18上预先设定的氧浓度条件之间的偏差,一次空气的流量。第二调节部20输出控制流量 使得来自氧浓度计16的输出信号达到预先设定的值。 这样可以防止生产NOX。
