摘要
本文对目前我国常用的选煤产品产率的计算方法——格氏法做了简要的评述;对格氏法、消元法、搜索法、各密度级灰分量法的计算结果进行了比较,指出格氏法存在的问题;并提出了考虑灰分因素进行产率计算的方法。同时。
A brief review is given of the calculation method of the coal processing products, proposed by K. Grumbrecht and commonly used in our country. A comparison is made between such calculation methods as Grumbrecht's method, the elimination method, the Lagrangian technique and the density-ash-content method, and between their calculation results. On this basis, problems are pointed out with Grumbrecht's method and a new method is proposed for the calculation of product yields with the ash content as the chief factor. Also suggested is that unified national standards be laid down for this calculation
