摘要
Abstract
Based on the verification results of ELHC test-bed,the prediction accuracy of pulverized coal explosion index Kd calculation and classification in the current technical specifications are compared and selected.Besides the calculation method is cumbersome and needs to be simplified.The ways of perfection are discussed from the aspects of theory and practice:1)The accurate and practical calculation formula in one step is selected to replace the step-by-step solution method.2)The feasibility of simple linear fitting formula for explosion index Kd is verified.Find out the error of fitting formula and fitting target in the existing literature.The correction formula of accurate conversion is deduced and put forward.3)The ELHC criterion is used to optimize the matching between the calculation of pulverized coal explosion characteristic index and classification.4)The explosion characteristic index of pulverized coal is used to improve the regulation of allowable outlet temperature of coal mill.关键词
