Overheating of boiler heating surfaces due to low water


Maintenance and Water Treatment for Your Process BoilerBoilers will overheat when the hot water that should be sent to the central heating system, taps or a hot water cylinder is being prevented from circulating. This is normally due to a failed part, such as the pump, or a blockage in the system. Why is an overheating boiler a problem?Improving Boiler Life and Reducing Cast Iron Boiler …The full article Improving Boiler Life and Reducing Cast Iron Boiler Accidents Introduction The original version of this article appeared in a 1975 issue of The Locomotive. But a key fact remains true today: overheating due to low water condition …

How to Destroy a Boiler -- Part 1If these so-called alkaline earth metals are present in the feed water, they can precipitate due to the heating in the boiler and form limescale which is deposited as a layer on the heating surfaces. If the formation of a layer or coating is not identified early on, this will lead to a deterioration in efficiency because the heat transfer is restricted.Finding the Root Cause of Boiler Tube FailuresDue to the critical need for water, modern boilers are equipped with automatic low-water trip switches. Some older boilers may not have these relatively inexpensive devices. If your boilers do not have low-water trips, run, don't walk, to the phone and initiate their installation.
