1. Introduction. The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [[1], [2], [3], [4]].The first generation of the coal mill classifier used static guide vanes to ...

The coal mill is one of the important auxiliary engines in the coalfired power station. Its operation status is directly related to the safe and steady operation of the units. In this paper, a modelbased deep learning algorithm for fault diagnosis is proposed to effectively detect the operation state of coal mills. Based on the system mechanism model of coal mills, massive fault data are ...

This was accompanied by a reduction in coalmill performance with increasing fractions of torrefied wood ( the particle size distribution shifted to larger diameters). Further modelling shows that from 50 to coal substitution (mass basis) is technically feasible without losses in boiler efficiency yet with significant reductions in ash ...
