Requirements of boiler feed water
WebWeekly: 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. WebPre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
