摘要
Abstract
On the basis of the test research on Shengli lignite coal grinding and calculation about large fan mill type-selection,the method of fan mill type-selection was proposed for lignite with low calorific value, low grindability,high moisture and used in high altitude conditions.It suggested the FM410.1300 fan mill be adopted and configured in 6+2 mode.When the ventilation volume of a single fan mill satisfies the re-quirements of coal dryness in BMCR load condition,the air coal ratio is 1.54.Furthermore,according to such parameters as coal fineness R90,pulverizing unit coal consumption,ventilation and booster pressure picked up in the commissioning curves of S02 mill,the corrected booster pressure of the FM410.1 300 fan mill is 1 594 Pa.The pipeline resistance is suggested to be matched with the corresponding booster pres-sure.Fan mill type selection calculation for small S02 mill and the field MB3600/1000/490 large scale fan mill was conducted respectively.The obtained booster pressure agrees well with each other,indicating u-sing the S02 fan mill to select the key parameters is reliable.关键词
