reasons for the failure of the boiler thrust

THRUST MONITORING ON BOILER FEED PUMP EQUIPMENT | The

Jul 22, 2019 · The three most common causes of thrust bearing failure (and how to avoid them) are as follows: Contaminants and Surface Finish. The presence of dirt and contaminants is damaging to every type of bearing, so its also an obvious cause of failure in thrust bearings.

Three Common Causes of Thrust Bearing Failure | Blog

A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions. The second kind is a fuel/air

Apr 02, 2012 · Failure of the thrust compensating disc (on machines equipped with one) Symptoms of high axial thrust can include high bearing temperature and/or premature thrust bearing failure. High axial thrust may appear gradually as the internal pump clearances open up from wear, or may show up suddenly such as when the pump is throttled back in flow.

Dec 08, 2017 · The drum design is suited for boiler feed pumps with daily starts, stops and frequent load changes as typical of a combined-cycle power plant. For the opposed impeller design, the suction of the impeller is opposed. Therefore, the axial thrust of the impellers is canceled by the opposing set.

Jan 23, 2009 · A high pressure boiler feed pump set will operate with pressurised fluid within the thrust bearing, permissible total wear on the thrust pad from new is typically between 0.75mm and 1.25mm, before inspection or replacement is required. Older BFP designs utilise a hydrodynamic (water) lubrication system driven from the impeller action.
