Poorly designed or matched boiler/burner combinations led to unstable combustion conditions causing vibration, increased noise levels and in rare occasions, even furnace explosions. With newer designs that optimize the boiler and burner design coupled with advanced controls technology like parallel positioning and O2 trim, the latest boilers can meet very low NOx levels with minimum, if any, CO.

1/4/2021 · In the present work, failure analysis has been carried out for induced draft ID fan blade used in coal fired boiler of thermal power plant. The vibrations were recorded in bearing housing prior to breakdown. Severe looseness in bearing causes an excessive vibration which in turn induced alternating stress in fan blade.

There are also some external factors to cause a decline in the performance of coal-fired boiler operation, for example, using coal quality is too low.Appear this situation will not only make in operation of the boiler heat loss increases, and exacerbate the slagging pipe scale, even cause
Read More14/9/2009 · Flow induced vibration in a boiler occurs when the vortex shed by the passing flow coincides with the natural frequency of the component or the gas column. Flow induced vibration can be experienced in the tube bundles of heat exchangers, in the heat transfer surfaces in boiler, in piping conveying fluids, in rotating machines like fans, etc.
