| 摘 要： | 对WGZl70／9．8-3型煤粉锅炉在冷态下进行了全面的测试分析，找出送、引风机及二次风门挡板开度与风量（速）的关系及四角喷燃下炉内速度分布及气流均匀情况；通过对试验结果的分析，确定送风机挡板开度在40％左右、两台引风机并联运行挡板各开45％左右较为适宜，燃烧中配风、各二次风门挡板的运行开度及对二次配风进行冷态调平，同时对炉内空气动力场进行飘带试验研究，经过合理的一、二次风配置，空气动力场良好，为锅炉的顺利点火及稳定运行提供依据。

| Abstract: | The characteristics of the WGZ170/9.8 -3 pulverized coal boiler were obtained based on cold test, Including the air velocity distribution in tangential firing boiler and the relation between air distribution with opening of each secondary air dampe,The test results had determined that the baffle of blower at around 40% and two parallel draft fan about 45% were relatively appropriate, and the air distribution and opening of each secondary air dampe and balancing the distribution of primary air and second air along the width direction of the boiler hearth were confirmed through test, and the aerodynamic field inside the boiler was investigated based on the tie - floating test. and good aerodynamic field can be obtained after distributing the primary air and second air reasonably, which guarantee the ignition and stable operation of the boiler. |
