Currently slime fuel mode, press the moisture level to divide, there are basically three levels: 1) slime coal slurry, the moisture content of up to about 40%, coal calorific value itself is not high, but also added so much water that makes it worth the loss of a large heat utilization, suitable only for the case of the thermal efficiency of less demanding, for optimum quality of slime small-scale use. 2) the use of domestic equipment, the slime squeeze agglomerate fluidized bed boiler combustion, coal moisture content can be reduced to about 32% to 34%, compared with slime CWS, nearly 10 percentage points lower water, the boiler combustion efficient and high energy use significantly improved, has formed the scale used on a large scale is a precedent for domestic use. But after all, an aqueous slurry is still more than 30%, the heat loss caused by water is still not a small number, can not be considered to be an ideal way. 3) the use of a lower moisture content slime. Slime will reduce the moisture content to about 20% or more lower than combustion, reducing the moisture content of more than 10 percentage points off than on this one way benefits are obvious. Into the power sector in the past but had slime coal preparation system caused the accident, has refused to burning coal, mainly because of the moisture content is too high slime mixed, and form a large group, cause problems. However, with the successful development of slime dryer, these issues also will be solved. This indicates that further reduce slime water reuse feasibility and realistic.
