减少氮氧化物的锅炉控制方法
摘要：
本发明涉及减少氮氧化物的锅炉控制方法。所述方法包括：第一设置操作(S100)：在第二控制阀(91)关闭而第一控制阀(90)打开的状态下，控制燃料阻尼器(12)和鼓风机马达(22)的转数，并且根据从载荷检测器(92)接收的载荷值驱动锅炉；以及第二设置操作(S200)：在第一设置操作之后根据载荷值驱动锅炉，其中控制所述第一控制阀(90)和所述第二控制阀(91)的开度，并且在通过第一检测传感器单元(70)和第二检测传感器单元(71)测量的NOx和氧气的浓度小于或等于NOx和氧气的目标浓度时，存储根据对应载荷值的第一控制阀(90)和第二控制阀(91)的开度的设置值。
摘要（英）：

The invention relates to a boiler control method for reducing nitrogen oxide. The method includes: a first setting operation (S100) of controlling the number of revolutions of a fuel damper (12) and ablower motor (22) in a state where a second control valve (91) is closed and a first control valve (90) is opened, and driving a boiler according to a load value received from a load detector (92); and a second setting operation (S200): driving the boiler according to the load value after the first setting operation, wherein the opening degree of the first control valve (90) and the opening degree of the second control valve (91) are controlled, and when the concentrations of NOx and oxygen measured by a first detection sensor unit (70) and a second detection sensor unit (71) are less than orequal to the target concentrations of NOx and oxygen, the set values of the opening degrees of the first control valve (90) and the second control valve (91) in accordance with the corresponding loadvalues are stored.
