【Abstract】 The theoretical calculation formula of the scale velocity of backwater system from the store field of coal ash has been deduced in this paper. It shows that mass ratio of coal ash water,water temperature,scale inhibitor concentration,backwater flow and so on are the main factors which affect the scale velocity. The determination of the parameters η Ca and f by simulated backwater is introduced. It combines the power plant with practice,and explains how to use the formula to determine the scale inhibitor concentration.更多还原
