Abstract
A rotary steam boiler comprises a rotatable member mounted in a housing including heating means. The rotatable member comprises a shaft with a plurality of axially extending ducts arranged about the shaft and a plurality of pipes each having opposite ends connected to one of said ducts and having a spiral configuration, the pipes extending radially about the shaft. Inlet and outlet heads are positioned at opposite ends of the ducts, respectively, and are arranged to communicate with the ducts during rotation of the shaft whereby steam may be continuously directed through the ducts and pipes to heat the steam as the shaft rotates. A preheater and a superheater increase the efficiency of the rotary steam boiler. The rotary steam boiler may be adapted for use with nuclear power stations.
Claims4
A rotary steam boiler comprising:
- (a) a housing defining a chamber and including heating means to heat a first sector of said chamber, the remaining sector of said chamber being cooler;
- (b) an assembly mounted for rotation about an axis in said chamber, said assembly comprising a plurality of elongated, open-ended ducts arranged in an annular configuration about said axis and extending substantially parallel to said axis and a plurality of heat exchange means arranged radially about said annular arrangement of ducts, each of said heat exchange means being connected to one of said ducts to permit steam to circulate between each of said ducts and the associated heat exchange means;
- and
- (c) an annular receiver head and an annular outlet head in sealing engagement with opposite ends of said plurality of ducts, respectively, said receiver and outlet heads being arranged to communicate with said plurality of ducts during rotation of said assembly;
- (d) said heating means comprising a burner and conduit means for feeding fuel and air to said burner, a preheater, a superheater, said conduit means for said air being arranged to pass through said preheater, and further conduit means passing through said superheater, said receiver head being arranged to direct steam into said assembly and said preheater such that said air supply to said burner is preheated by said steam during passage through said preheater;
- (e) whereby steam may be directed through said receiver head, said ducts, said plurality of heat exchange means and said outlet head and may be heated in said heat exchange means during passage of said heat exchange means through said heated first sector of said chamber.
