我公司一期工程安装的 2台国产引进型 30 0MW机组 ,分别于 1 995年 7月和 1 2月相继投产 ,均配直吹式制粉系统。机组投产不久 ,就出现磨煤机风量及出口温度较难调节等缺陷 ,风量及出口温度控制自动很难投入。通过对 2套自动的逻辑、定值以及整个一次风系统的分析 ,发现风量及温 Two sets of domestically-introduced 30-MW units installed in the first-phase project of our company were put into operation successively in July and January of 1995, both of which were equipped with direct-blowing pulverizing system. Unit put into operation shortly after the emergence of mill air volume and outlet temperature is difficult to adjust and other defects, the air volume and outlet temperature control is difficult to put into. Through the analysis of 2 sets of automatic logic, setting value and whole primary air system, it was found that air volume and temperature
