CODE REQUIREMENTS AND MAINTENANCE CONCERNS: FOR YOUR BOILER WATER LEVEL INSTRUMENTATION

摘要

The vital information that operators require from the water level instrumentation on your boiler drums may be compromised through code violations or lack of maintenance. A routine observation (walk down) of these critical instruments does not always result in identification of the issues that should be resolved. Annual boiler inspections traditionally reveal many serious deficiencies that range from absent or malfunctioning code-required level instruments to piping concerns and even isolated or inoperable instruments. While many plants take pride in procedures and policies to ensure their water level instruments are operating and maintained properly, the number of neglected, deteriorated, and field-modified applications is a real concern. If you have any doubts, ask your local boiler inspector.
