Abstract
This paper will introduce the production technology of COM and CWM including the recent technology in our company.
COM is made by the two lines of production facilities with capacity of 70t/h each and the annual production amounts to about 700, 000 tons.
Based on the selection of the coals and additives and optimization of the coal particle size distribution, we are producing about 70, 000 tons of CWM annualy produced by two lines of production facilities with capacity of 15t/h each.
We succeeded in development of the technology to produce super low ash (about 1.5%) CWM using Cerrejon coal. And then, We will perform the combustion test of the low ash CWM at Tomakomai from this August as a national project. We can also produce the CWM from high ash content coal. So we established the technology to produce CWM from bituminous coals ranging from one to thirties percent ash.
