    • Provided are a solid-fuel burner (60) suitable for controlling a flame formed by combustion of fuel ejected from the burner (60) and controlling the temperature distribution in a furnace, a combustion device using the solid-fuel burner (60), and a method of operating the combustion device. Gas outlet nozzles (81, 82) and a restriction (obstacle)(19), which is placed on the downstream of the gas outlet nozzles (81, 82), are arranged in a fuel nozzle (10), and a relatively larger amount of gas is ejected from one (81) of the gas outlet nozzles. This provides a circumferential variation in the distribution of fuel concentration. Further, the presence of the restriction (obstacle)(19) on the downstream side increases a difference in the fuel concentration. The flame forming position can be changed by providing the fuel concentration with such a circumferential difference. Regulating the flow rate of gas flowing in the gas outlet nozzles (81, 82) allows the temperature of combusted gas at a furnace outlet, the temperature of heat transfer tubes arranged on a furnace wall surface, the temperature of fluid flowing in the flow transfer tubes, the temperature of heat transfer tubes arranged in the furnace and in a gas duct on the downstream side of the furnace, and the temperature of gas flowing in the heat transfer tubes to be controlled to constant levels.
    • 提供一种固体燃料燃烧器(60),其适用于控制由燃烧器(60)喷出的燃料的燃烧形成的火焰并控制炉内的温度分布,使用固体燃料燃烧器(60)的燃烧装置,以及 一种操作燃烧装置的方法。 放置在气体出口喷嘴(81,82)下游的气体出口喷嘴(81,82)和限制器(障碍物)(19)被布置在燃料喷嘴(10)中,并且具有相对较大的量 的气体从一个(81)气体出口喷嘴喷出。 这提供了燃料浓度分布的周向变化。 此外,下游侧的限制(障碍物)(19)的存在增加了燃料浓度的差异。 可以通过提供具有这样的周向差的燃料浓度来改变火焰形成位置。 调节在气体出口喷嘴(81,82)中流动的气体的流量允许炉出口处的燃烧气体的温度,布置在炉壁表面上的传热管的温度,流动转移中流动的流体的温度 管,布置在炉子中的传热管的温度和炉的下游侧的气体管道中的温度以及在传热管中流动的气体的温度被控制到恒定水平。

    • This invention provides a solid fuel burner, which, while rendering the capacity larger than that in the prior art, can suppress an increase in an unignited region and thus can realize the prevention of an increase in NOx density in a combustion gas and the prevention of a lowering in combustion efficiency, and a combustion equipment and boiler comprising the burner. The burner comprises a fuel-containing fluid supply nozzle (12) which supplies a fuel-containing fluid, from a connection part in a fluid transfer flow passage (10) for transferring a fuel-containing fluid comprising a fuel and a medium for the transfer of the fuel, toward an outlet part provided on the wall of a furnace (4). The fuel-containing fluid supply nozzle (12) in its cross section perpendicular to the direction of flow of the fluid is in a rectangular, elliptical, or approximately elliptical form having major and minor axis parts from a connecting part (10a) in the fluid transfer flow passage (10) toward the outlet part provided on the wall surface of the furnace (4). Further, the area of a cross section perpendicular to the direction of flow of the fluid is gradually increased from the connecting part in the fluid transfer flow passage (10) toward the outlet part. One or more air supply nozzles (15) for supplying combustion air are provided on the peripheral part of the nozzle (12).
