    Abstract: PURPOSE: A boiler is provided to maintain the excellent combustion state by reducing carbon monoxide density, incomplete combustion material, attached ash and the like near the sidewall with a simple structure. CONSTITUTION: The boiler includes the components such as:powdered coal as a fuel; a feed piece for feeding gas which transfers the powdered coal to a multi-stepped burner; a feed piece for feeding the combustion air to the multi-stepped burner; and a control piece including a feed piece for feeding jet gas to a gas port and for controlling the jet flow from the gas port on the basis of the load demand of a boiler and the coal type information to decrease the jet flow from the gas port if a load of a boiler is low and to increase the jet flow from the gas port if the load of a boiler is high.

    Abstract translation: 目的:提供一种锅炉,通过以简单的结构减少侧壁附近的一氧化碳密度,不完全燃烧材料,附着的灰分等来保持良好的燃烧状态。 规定:锅炉包括:煤粉为燃料; 用于供给将粉煤转移到多级燃烧器的气体的供给件; 用于将燃烧空气供给到多级燃烧器的进料件; 以及控制件,其包括用于将气体输送到气体端口并且用于基于锅炉的负载需求控制来自气体端口的喷射流的进料件和煤类型信息,以减少来自气体端口的喷射流 如果锅炉的负载较低,并且如果锅炉的负载高,则增加来自气体端口的喷射流量。
