May 01, 2011 · The steam capacities of these radiant boilers ranged from 400,000 to 1,000,000 pounds of steam per hour. Consequently, the small city- and town-owned power plants became obsolete, as the utility companies could now produce enough electricity for larger residential areas and industrial companies.
Historically, the first central stations used reciprocating steam engines to drive generators. As the size of the electrical load to be served grew, reciprocating units became too large and cumbersome to install economically. The steam turbine rapidly displaced all reciprocating engines in central station service. Fuels Coal
