Causes for Flame Failure in a Boiler and Operator Action

2009/10/15Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up. Get price

Hydraulic system contamination: causes and solutions

2018/04/19Some researchers have found that the presence of solid particles in hydraulic oil makes it even easier for cavitation bubbles to form. Metal particles that remain in suspension can cause additional erosion as they strike against valve spool metering notches and valve port edges during the high-velocity flow that occurs as a valve is first opening, or just before it closes.Get price
