Papermaking waste water resource recovery - a new approach of preparation of coal water slurry

摘要

Papermaking waste liquid instead of water to prepare coal water slurry, which aim is turning waste into treasure. Not only can the waste fundamentally eliminate environment pollution, but also saving a lot of water resources. Because the waste contains large amounts of sodium, which is one of the main reasons of heating surface slagging of boiler. So it is necessary to improve and increase the soot blowing device of heating surface of boiler.
