Abstract

PURPOSE: To improve scale removal efficiency by using an effective condition equation and an air mixing equation.
CONSTITUTION: After a system condition is set to satisfy an effective condition equation 0.05=V1/V2 (where V1 is water velocity (m/s) after the compressed air is mixed) derived at by using a water head loss coefficient K1 up to the air mixing point, a water head loss coefficient K2 after the air mixing point and an effective water heat H (m) of the system which are obtained from the system specifications and a required water velocity V2 (m/s) corresponding to the property of the scale obtained from the equipment specifications, a nozzle 4 designed to satisfy an air mixing equation a=c.A (V2-V1)γ2/Voγ1 (where a is cross sectional area of a compressed air mixing nozzle (m2), Vo is mixed air velocity (m/s) from the nozzle, γ1 is specific weight of a mixing air (kg/m3), γ2 is specific weight of the mixture (kg/m3) and C is correction coefficient) is used to remove the scale.
