The major problem that deposits cause is tube failure from overheating. This is due to the fact that the deposits act as an insulator and excessive deposits prevent efficient heat transfer through the tubes to the water. This causes the metal to become overheated and over time the metal fails.
Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion. Water chemistry upset, such as what can occur from condenser leaks, particularly with salt water cooling medium. Leads to acidic (low pH) contaminants that can be concentrated in the deposit.
Common Causes Of Boiler Leaks And How To Repair ThemAllen
Aug 28, 2017 · Most boiler leaks are caused by corrosion, faulty water pipe connections, a broken seal, or a damaged valve or pump. To save time and money, you can try to identify the cause of a leak before initiating repairs or contacting a repair company. However, if your boiler is gas-operated you should contact a professional to conduct repairs immediately.
Causes of Soot Soot is a normal byproduct of combustion, which is why cleaning the combustion chamber, the heat exchanger, plenum chamber and flue pipe …
Jan 15, 2021 · The zone valve is faulty : Check the zone valve for proper operation. The water pipe should be hot up to and beyond the zone valve. If the valve is faulty or stuck, lines will be hot up to the valve but will cool off slightly beyond the valve. Have a faulty valve replaced by a repair professional.

Seven Telltale Signs Your Boiler Needs To Be Replaced
CAUSES OF TUBING FAILURES. Fuel ash corrosion. Fuel ash corrosion is a high-temperature phenomenon in coal and oil-fired boilers. In oil-fired boilers, sodium sulfate combines with vanadium pentoxide to form a very corrosive coating of molten "slag" on the fireside tube surface of superheater and reheater tubes.
