Steam engine generators

  • Assumed water rate of 38 lb steam/KWH produced@10 psig backpressure.

  • Assumed water rate of 26 lb steam/KWH when condensing at 10 in.Hg.

  • Inlet steam pressure of 150 psig.

  • The twin steam engines are fed 21,000 lb/hr of 150 psig saturated steam except for 10 hours/week when steam flow is reduced to 11,000 lb/hr during bypassing for kiln startup.

  • This arrangement results in a weighted average generator output of 702 KW during operation, right as the rating of the combined generators.

Initial maintenance needed

The main rod bearing of both engines needs to be re-poured and the crankpin on at least the Elliott needs to be turned.

Both engines and steam separators need to be abated.
