Lower the actual boiler water level to the 1st low (by evaporation), and then blow down to the 2nd low. The main reason for this weekly test is to ensure that the alarm is given, and at the correct level, when the level drops slowly in the boiler (because floats could stick). 2. A high alarm is usually tested weekly.

Boiler Feed Water - Lenntech

Boiler feed water is used to produce steam. The pressure of the steam (0,5 - 100 bar) determines the temperature and energy capacity, but also the quality of the feed water. The general rule is the higher the pressure the more strict the quality of the boiler feed water. Problems caused by impurities in the feed water are: Scaling. Corrosion.
