Study on selection and slurry ability of coal-water slurry additives for Yulin coal

The influence of different additives on synthetical properties of Yulin coal water slurry was mainly discussed.When the ratio of napthalene A to ligin A is 40∶60,the suitable concentration of coal water slurry for Jinniugou is 64% and the adding amount of additive is 0.5%.The suitable concentration of coal water slurry for Shanghegou is 63% and the adding amount of additive is 0.6%.
