| 摘要 |
A power generation unit comprising a turbine for extracting energy from a vaporous power fluid and including means for directing the power fluid generally downward therethrough, a tubine wheel wherein the flow of the power fluid past the turbine wheel causes rotation thereof, and a vapor discharge port substantially directly below and at least substantially coextensive with the horizontal cross section of the vapor flow path as the vapor flows past the turbine wheel. The unit further comprises power means for generating power, means for transmitting energy extracted from the power fluid by the turbine to the power means to generate the power, and a condenser located below the turbine for condensing the vaporous power fluid and including a vapor inlet port substantially coextensive with the vapor discharge port of the turbine.
