电站锅炉风速在线监测系统及测速方法
摘要：
电站锅炉风速在线监测系统及测速方法。目前国内燃煤电厂的锅炉运行风管内的风速缺乏检测，运行操作几乎都是运行人员根据总风压，风机电流和调节挡板开度，给煤机转速，一二次风静压等参数来组织和调整燃烧。一种电站锅炉风速在线监测系统，其组成包括：风管（1），所述的风管上部安装有法兰（5），所述的法兰与测速装置（2）连接，所述的测速装置具有总压取压管（3）、静压取压管（4），所述的总压取压管与所述的静压取压管连接，所述的总压取压管上连接有引压线头（7）、二次滤室（6），所述的引压线头与所述的二次滤室连接。本发明应用于电站锅炉。
摘要（英）：

The invention discloses a power station boiler wind speed on-line monitoring system and a speed measuring method. Currently, the domestic fuel coal power station is lack of the detection of wind speed in the operation air duct in the boiler, and the operation, for example, the organization and the adjusting of the combustion can be carried out by the operators according to the parameters such as the total wind pressure, the draught fan current, the adjusting baffle opening, the feeder rotating speed, and the primary, secondary wind static pressure. The power station boiler wind speed on-line monitoring system comprises an air duct(1). The upper part of the air duct is provided with a flange(5), which is connected with a speed measuring device(2). The speed measuring device is provided with a total pressure tapping pipe (3) and a static pressure tapping pipe (4), which are connected together. The total pressure tapping pipe is connected with a pressure drawing line end (7) and a secondary filtering chamber (6), and in addition, the pressure drawing line end is connected with the secondary filtering chamber. The power station boiler wind speed on-line monitoring system and the speed measuring method are used for the power station boiler.
