Discussion on total moisture deviation and treatment method in coal sampling,preparation andtest process
The moisture content of coal is an important quality and measurement index.According to the mechanism of moisture loss,the sources of moisture deviation in the process of coal mining and gasification include crushing loss,evaporation loss and sampling deviation.According to the mechanism of water loss,The author puts forward the treatment methods of various moisture loss:the value of crushing loss and sampling deviation should be determined by experiment;evaporation loss should be avoided by technical means.Practice the treatment of total moisture deviation in a project,the conclusion was:compared with the current treatment of total moisture deviation,the total moisture deviation treatment method proposed in this paper was 0.7%higher on average.The total moisture deviation treatment method proposed in this paper is superior to the current total moisture deviation treatment method.
