How to Handle Both Forced Draft Fans Trip in Running …

29/7/2009 · Boilers have forced draft (FD) fans to supply air for combustion of fuel. Any trip of major equipment in boiler causes the boiler parameters to vary widely before it stabilizes depending upon the action taken by the operator. The important factors to be understood in a trip of equipment in a boiler are mainly four, the specific cause of trip, plant response to the trip, immediate operator

Finding the Root Cause of Boiler Tube Failures

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 start-up, obstructing steam …
