Abstract：In order to improve efficiency and security of conventional industrial pulverized coal conveying technologies,the working princi-ple and application state of dilute phase pneumatic positive pressure conveying( Method 1),negative pressure conveying( Method 2)and dense phase pneumatic conveying(Method 3)were introduced. The technical features,investment,energy consumption and environmental performance of above three methods were compared. The mechanism of dense phase pneumatic conveying and the mainstream plug flow dense phase conveying technologies were introduced. The results showed that,Method 3 had the shortest conveying distance,Method 1 had the largest energy loss,Method 2 had the highest solid-to-gas ratio,the lowest energy consumption,material abrasion,noise and frictional heating occurrence probability which was suitable for pulverized coal conveying.
