FREQUENCY OF THE ANALYSES

The frequency of the analyses depends on the use of the 

generator and the quality of the water used; however, it is 

advisable to check the pH value, the total hardness and alkalinity 

of the feed water and operating water every two days. It is good 

practice, especially in variable operating conditions, to monthly 

subject  a  significant  sample  of  the  feed  water  and  operating 

water to a full analysis.

It is also good practice to visually check the condensate returns 

for any highly polluting oily substances (reduction of evaporation 

on the surface of the boiler water due to a layer of oil).
