如图所示,在距离喷枪轴线900 mm处垂直摆放红外热像仪,水平高度与喷枪轴线保持一致,调节镜头角度与焦距直至可以清晰的显示出焰流预扩散平面。
As shown in the figure, the thermal imaging camera is placed vertically at a distance of 900 mm from the gun axis, the horizontal height is kept in line with the gun axis, and the lens angle and focal length are adjusted until the flame flow pre-diffusion plane can be clearly displayed.
