Byron Jackson Boiler Feed
Application: Boiler Feed
Pump Details: Byron Jackson HSB 14-Stage
Pump Type: Barrel
When a utility's Byron Jackson boiler feed pump lost flow and experienced excessive vibration, the pump was pulled and sent to Hydro.Several issues were uncovered; there were abnormal clearance increases throughout all the wear components; there was severe case erosion as well as erosion at the volute bushing and take off bushing; and it was eventually learned that the pump was given too short a warm up time before start up, which caused leaks and erosion at the split lines.
The utility agreed to the upgrades and modifications suggested by Hydro and began executing a detailed installation procedure. The pump was placed in operation and after 5 years there was less than 2% degradation in performance.
Mean-time-between-repair was increased from 18 months to 6 years with an increase in overall efficiency which enabled the station to achieve an energy savings of over $100,000 per year.
