May 25, 2016 · Tables 2 and 3 show recommended boiler water chemistry limits. Customized limits for a specific boiler depend on the steam purity requirements for the boiler. Boiler and laboratory experience indicate that, under some conditions, phosphate-magnetite interactions can degrade protective oxide scale and corrode the underlying metal.

minimum recommended low limit for warm-start boiler

Mar 01, 2010 · LOW LIMIT: The DIFF is SUBTRACTIVE. If you have the LOW set at 110, and the LOW DIFF at 10, as the boiler COOLS DOWN, the burner will fire at (110 - 10) or 100. The burner will continue to fire until the temperature in the boiler is at the LOW setpoint, or 110. Another example: LOW still …

Water quality of bolier - Boiler and Pressure Vessel

As a rule of thumb, about 1000 ppm can be considered a safe maximum. A hard water containing 200 ppm in the feedwater would tolerate five concentrations in the boiler (200 times 5 = 1000). On the other hand, a soft water with 25 ppm could be concentrated 40 times before reaching the critical point (40 times 25 = 1000).

Aquastat settings: Best High, Low, & DIFF Settings on a

Setting a high limit at 180 or above is wasteful. I set my high limit at 160. The lower boiler temp is unnoticeable in the home heating. Actually my oil bill dropped 25%. Low limit is always 20 degrees less than high limit. The furnace does not come on all the time as before. My circulators stay on longer to move heat to baseboard pipes.
