摘要： PROBLEM TO BE SOLVED: To improve the transportability of dried pulverized coal as well and to stably execute blowing of the pulverized coal by mixing solid compd. powder of a specific grain size at a specific ratio with the pulverized coal at the time of using the pulverized coal in a metallurgical furnace and combustion furnace. SOLUTION: The flow property of the pulverized coal varies with the kinds, particle sizes and difference in moisture of the pulverized coal to be used at the time of using the inexpensive pulverized coal in the metallurgical furnace, such as blast furnace, and the combustion furnace, such as boiler, and the discharging and transporting conditions of the pulverized coal from a hopper vary largely thereby, making the smooth transportation infeasible. The dust consisting of the solid compds., such as SiO2 , and other metal oxide, etc., having a volumetric average grain size of =30 of the pulverized coal to be used for the purpose of ameliorating the shortbacks described above. The defects, such as piping closure during the transportation by the gas, the scaffolding of the pulverized coal in the hopper and blow-by, are eliminated and the stable blowing of the pulverized coal to the metallurgical furnace, etc., is assured.

摘要： PURPOSE: To greatly improve the transportability of pulverized coal having an average HGI of raw coal of a specific value or above by sticking an org. compd. which has polar groups and is substantially soluble in water to the pulverized coal. CONSTITUTION: This pulverized coal transportability improving agent consists of the org. compd. which has the polar groups, such as anionic surfactants, cationic surfactants, amphoteric surfactants, lower fatty acids and lower fatty acid salts, and is substantially soluble in water. Such pulverized coal transportability improving agent is stuck to the dried pulverized coal having the average HGI (average grindability index) of the raw coal of >=30. As a result, the transportability of the pulverized coal is greatly improved and, therefore, the restriction on coal kinds is removed, piping closing and scaffolding in a hopper are prevented and the stable blowing of the pulverized coal in large amt. are made possible.
