摘要
W型火焰锅炉在发电厂有着广泛应用。但是,目前此种锅炉二次风供风系统的调节是凭经验进行的,为了使它的调节更迅速、更有效,运用了流体力学管路理论,对此种锅炉二次风供风系统建立数学模型,进行计算分析,得到在任一给定工况下各档板开度的计算方法和计算公式,并进行了实例计算,计算结果与现场运行情况基本一致。表明:这种计算方法在实际工程应用中是可行的。今后当工况发生改变时,就可以方便地运用本计算方法,指导各档板的调节。
W burning boiler is widely used in power plants. But nowadays the adjustment of the secondary wind system in the kind of W burning boiler is made by experience. In order to make the adjustment of it more rapidly and more efficiently, the pipeline theory of fluid mechanics is used. A mathematic model is made for the secondary wind system in the kind of boiler, and calculation and analysis is done. The method and formulation of calculation of baffle's opening degree in any given working conditions is obtained,and calculation is made on a specific example. These results are consistent primarily with running conditions on the site. So the method of calculation is practicable in the practical engineering application and convenient to use the calculation method to guide the adjustment of baffles when the working conditions is changed.
