In Reply to: Water surging in sightglass hitting low water cutoffs. posted by Steve Hill on January 12, 2010 at 09:27:59:
: We recently had two 100hp electric boilers installed at our facility. We run low pressure system (10psi)in one common loop. The issue I'm having is when boliers are called for in the automation sequence they ramp up to full max (1200amps) run for about 3 minutes and shut off on low water. They have been recently boiled out to eliminate greases,oils etc. Should these boilers ramp up so quickly? I have a ph of 8.5 and a conductivity of around 200.
had this happin on a nat gas boiler we installed. the surging happind a year after we installed we had to skim the boiler alot and use some tsp we also skim the boiler every six months now the customer does not treat his water
