Abstract
Supplementary means for heating liquid in a steam producing boiler comprising an electrical heating unit located in the boiler, the current for which is produced by an electric generator driven by a steam operated turbine. The turbine may utilize all or only part of the steam output of the boiler. Where the turbine uses substantially all of the steam, the generator driven by the turbine will have excess capacity to be used to drive a motor. Where the turbine uses only enough steam to drive a generator sized to meet the needs of the heating unit, the balance of the steam will ordinarily be used to drive some major prime mover or to supply heat to a heating system.
Claims3
In combination, a first boiler in which steam may be generated, a conventional source of heat for said boiler, a turbine, means for delivering steam from said first boiler to said turbine, a generator driven by said turbine, an electrically operated heating element located within said first boiler energized by current from said generator, said heating element adapted to act when heated as a supplementary source of heat to aid in the production of steam in said first boiler, the steam exhausted from said turbine passing through a pipe to a condenser and a pump for returning the condensate to said boiler, a second steam boiler, means for heating the water in said second boiler to generate steam, said heating means for said second boiler comprising a) an electrically operated heating element located within said second boiler and energized by current from said generator, and b) means for delivering steam from said first boiler to said turbine which means comprises a steam carrying pipe that has part thereof positioned in the water of said second boiler, and means for utilizing the steam generated in said second boiler.
