循环流化床锅炉(CFB)是近年来发展起来的新一代高效、低污染清洁燃烧技术.风帽作为其重要装置会直接影响到循环流化床锅炉的运行。针对风帽阻力在已搭建的风帽阻力冷态试验台上,进行了Γ型风帽、支管角度分别为90°(60°、120°)且改变出口孔径时侧箭头型风帽的阻力试验。实验过程中,用U型压力计测量不同流量下风帽入口处的压力,计算风帽的压降大小,运用Origin软件进行数据处理,并对不同风帽的阻力进行比较,得出与Γ型风帽阻力最为接近的侧箭头型风帽形式。
Circulating fluidized bed boiler (CFB) is a new generation of high efficiency, low pollution clean combustion technology developed in recent years.Heather hood as its important device will directly affect the operation of circulating fluidized bed boiler. According to the resistance of the hood, the resistance test of the side arrow hood with the Γ wind cap and branch pipe angles of 90 ° (60 °, 120 °) and changing the outlet aperture was carried out on the cold hood resistance cold stage. During the experiment, the pressure of the hood at different flow rates was measured with a U-type pressure gauge to calculate the pressure drop of the hood. The data were processed by Origin software and the resistance of different hoods was compared. Close to the side arrow-style hood form.
