ENVIRONMENTALLY FRIENDLY TECHNOLOGY

Cooling water blow system

A part of circulating water should be blown to prevent degrading of cooling water quality.

Since concentration ratio is considered about 3 to 4 blowing, water quantity is calculated as follows.

N: Concentration ratio generally N=3 M : Make-up water volume

E : Evaporation loss

E=

3,0241.85 (exhaust factor)

 

575 (Latent heat of evaporation at 40° C)

 

W

: Splashing loss

generally W=0.2% of circulating water volume

 

 

 

 

 

 

 

 

B

: Blow volume
