在煤粉炉燃烧调整试验中,一、二次风风量和出口风速的调整是建立正常的空气动力场和稳定燃烧所必须的试验项目。在试验过程中,为及时掌握各工况下的一、二次风量和出口风速,试验人员要采取多种测试手段和耗费相当多的人力进行测量。在正常运行中,如若因负荷、煤质改变或其它原因,需要调整一、二次风,一般也都没有运行表计可供监视。天生港发电厂于1979、1980年先后投产两台国产125机组,配套上海锅炉厂400吨/时超高压中间再热锅炉。在江苏省电力试验研究所的支持下,安装了二次风双机翼型测速元
In the pulverized coal furnace combustion adjustment test, the adjustment of the primary and secondary air volumes and outlet air velocities is a necessary test item for establishing a normal aerodynamic field and stable combustion. In the course of testing, in order to grasp the primary and secondary air flow and outlet wind speed under various working conditions in time, the test personnel should adopt a variety of testing methods and spend a considerable amount of manpower to make measurements. In normal operation, if due to changes in load, coal quality or other reasons, the need to adjust the primary and secondary air, are generally not running the meter for monitoring. Tianshenggang power plant in 1979, 1980 has put into operation two 125 sets of domestic production, supporting the Shanghai Boiler Plant 400 tons / hour EHV intermediate reheat boiler. With the support of Jiangsu Electric Power Research Institute, a dual airfoil speed sensor was installed
