Length measurement system of wet plume

The application discloses length measurement system of wet plume, this system are used for measuring concrete mid point, 3 coordinates of predetermined control point in unified coordinate system thatare measuring the outlet flue of chimney to the length of coal fired boiler's the wet plume of chimney exhaust, measure the tangential horizon angle of every control point to the tail end of wet plume, calculate tail end to the distance at the center of the outlet flue of chimney based on the direction method of intersection, according to the coordinate at the coordinate of horizon angle, chimney,control point, the length of the plume that obtains wetting. The length of the wet plume that obtains is an important quantitative data of wet plume promptly to improvement for wet plume provides effectual foundation. 本申请公开了种湿烟羽的长度测量系统，该系统用于对燃煤锅炉的烟囱排出的湿烟羽的长度进行测量，具体为测量烟囱的出烟口的中点、3个预设的控制点在统的坐标系统内的坐标；测量每个控制点到湿烟羽的尾端的切线的水平角；基于方向交会法、根据水平角、烟囱的坐标、控制点的坐标计算尾端到烟囱的出烟口的中心的距离，得到湿烟羽的长度。得到的湿烟羽的长度即是湿烟羽的种重要的定量数据，从而为湿烟羽的治理提供了有效的依据。
