    • An image forming system having a preceding stage apparatus for forming a toner image on a paper sheet, and a subsequent stage apparatus, connected downstream of the preceding stage apparatus, for forming a toner image on the paper sheet ejected from the preceding stage apparatus, includes: a first maintenance counter correlating with a part, subject to maintenance, in the preceding stage apparatus; a second maintenance counter correlating with a part, subject to maintenance, in the subsequent stage apparatus, in response to the first maintenance counter; a counter control section for increasing a count value of the first and the second maintenance counters by a first and a second designated value, respectively, in response to formation of a toner image on the paper sheet; and a setting section for setting the first and second designated values individually based on an operation mode of the image forming system.

    • A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal. An additional air nozzle for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle is provided in the fuel nozzle, thereby encouraging mixing between the fuel and air in the fuel nozzle. Further, the amount of air supplied from the additional air nozzle is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle is increased so as to increase the oxygen concentration of the circulating flow formed downstream of the outside of the outlet of the fuel nozzle, whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle is decreased, and a flame is formed away from the fuel nozzle in such a way that burner structures and furnace wall will be less subjected to radiant heat.
    • 一种固体燃料燃烧器及其燃烧方法,其适用于鼓励燃油点火并避免由燃烧灰引起的气塞,其中使用低氧浓度(废气燃烧气体)的气体作为棕煤等低等级固体燃料的载气。 在燃料喷嘴中设置有用于喷射在燃料喷嘴的圆周方向上具有速度分量的附加空气的附加空气喷嘴,从而促进燃料喷嘴中的燃料和空气之间的混合。 此外,响应于燃烧负荷的差异,调节从附加空气喷嘴供给的空气量。 在轻负载下,增加从附加空气喷嘴供给的空气量,从而增加在燃料喷嘴出口外侧下游形成的循环流的氧浓度,从而确保燃烧稳定。 相比之下,在重负载下,从附加空气喷嘴供给的空气量减少,并且燃烧器结构和炉壁的辐射热不太可能形成远离燃料喷嘴的火焰。
