boiler heat-hot surface short temperature explosion tube phenomenon

Boiler Tube Failures - Semantic Scholar

A common cause of explosion is the runaway firing condition that takes place when the boiler's burner does not shut off. In this case, when the hot-water heater is connected to the city water supply on one side and the building hot-water service on the other, the check valve will shut off and no back pressure will go into the city side.

Finding the Root Cause of Boiler Tube Failures

Symptoms: Failures result in a ductile rupture of the tube metal and are normally characterized by the classic fish mouth opening in the tube where the fracture surface is a thin edge. Causes: Short-term overheat failures are most common during boiler start-up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler …

Failure analysis of high temperature superheater tube (HTS

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.
