在工业锅炉进行燃烧调整过程中,为了保持合适的风煤比和配风比,必须对风量进行连续的测量和监视。但是,以往由于缺乏适用于工业锅炉的测风手段,一般都用风压或输道挡板来代表风量。这显然不能适应科学的进行燃烧调整的需要。为此,笔者在某厂锅炉二次风支风道上采用流线型机翼风量计测量风量,取得了很好的效果。流线型机翼风量计(下称机翼风量计)与传统使用的测风装置相比,具有需要的直管段很短、压力损失小、差压信号 In the process of adjusting the combustion in industrial boilers, in order to maintain a suitable ratio of air to coal and air distribution, the air volume must be continuously measured and monitored. However, in the past, due to the lack of wind measuring instruments suitable for industrial boilers, air pressure or duct baffles were generally used to represent the air volume. This obviously can not meet the scientific needs of the burning adjustment. To this end, the author of a plant boiler secondary air duct using streamlined wing air flow meter to measure air volume, and achieved good results. Streamlined wing air flow meter (hereinafter referred to wing air flow meter) Compared with the traditional wind measurement device, with the need for straight pipe is very short, the pressure loss is small, differential pressure signal
