MPS-HP-Ⅱ型中速磨煤机已经应用于70多个高水分的褐煤工程(设计煤Mt<35%),其中近50个项目已经投入了运行,磨煤机的出力均达到或超过设计值,设备运行状况良好。目前许多电厂的运行煤质与设计煤质偏差超出国家标准的要求,有些电厂(如大唐长春第三热电厂)的原煤水分更高,甚至达到Mt=40.9%,超出设计值18.5%。本文将主要以大唐长春第三热电厂MPS190HP-Ⅱ型中速磨煤机项目为例,简介新型磨煤机在磨制超设计值高水分褐煤工程上的实际应用。
MPS-HP-II Medium Speed Pulverizers have been used in more than 70 high-moisture lignite projects (<35% for design coal), of which nearly 50 have been put into operation and mill outputs have reached or exceeded Design value, equipment in good condition. At present, the deviation of operating coal quality and design coal quality of many power plants exceeds the requirements of national standards. Some power plants (such as Datang Changchun No.3 Thermal Power Plant) have higher raw coal moisture even reaching Mt = 40.9%, exceeding the design value by 18.5%. This paper will mainly take Datang Changchun No.3 Thermal Power Plant MPS190HP-Ⅱ Medium Speed Pulverizer Project as an example to introduce the practical application of the new pulverizer on the ultra-design high moisture brown coal project.
