Abstract
The West Burton power plant (a subsidiary of EDF Company) commissioned between 1967 and 1969 is a 2000MW capacity power station consists of four similarly Boiler and Turbo Generator (TG) sets (generating unit). Each of the TG units is made up of several turbine stages (i.e. high pressure (HP) turbine; an intermediate pressure (IP) turbine and three low pressure (LP) turbines), in addition to a generator and an exciter. Along with the main generating units’ assets, there are number of auxiliary equipments such as; condenser; air ejector; feed water pumps and primary air (PA) fans. Each boiler has two primary air (PA) fans, used for supplying primary air to the mills and conveying pulverised fuel into the boiler unit. As part of operational performance enhancement strategies, two of the boilers’ (unit 1 & 4) PA-fans have been retrofitted with new electric motors, while the other two boilers (units 2 & 3) still possess their original electric motors. High levels of vibration readings were recorded on unit 3 PA-fan-B’ electric motors’ bearings on both; drive and non-drive ends. Hence a number of vibration measurements were conducted on this machine to find out the root cause of the increase on the machine vibration.
