Experimental Study on MPS-HP-II Medium Speed Mills Applied on Unite Using High-Moisture Contained Coal

Abstract:

As a new type miller imported from Germany Company Babcock, MPS-HP-II becoming more and more popular because of its outstanding performance in grinding high moisture contained coal. But in daily operation in power plants, the operators encounter with many problems, such as a lack of output, and difficulties in finding proper operation point. In this paper, a we put up with a proper way to calculate the max output of MPS-HP-IImiller, which is demonstrated by experiment. Also we find the optimized working point of MPS-HP-IImiller by analysing the experiment result got by changing the primary air flow rate, separator angel, output and load force.
