ABSTRACT:
Set out herein is a fuel cell power plant for use with irrigation systems wherein the fuel cell is utilized to generate electric current to drive a pump motor. This pump motor drives a first water pump which receives water for distribution through a traveling irrigation system, the output of the first pump first conveyed into a condenser heat exchanger connected to a steam engine or turbine cycle. The fuel cell itself is contained within a boiler assembly and the heat of production of the electric power is used to generate steam which is sent to the steam engine. In the course of cooling the condenser gases of the steam engine the irrigating water is passed through a second pump driven by the steam engine and it is through this second pump that the pressure is raised sufficiently to allow for the necessary spraying fans. To improve the condenser efficiency part of the condensate or the ullage thereof is connected to one of the spray heads on the irrigation system in a venturi nozzle which thereby lowers the back pressure thereof. The lower portion of the condenser or the liquid part thereof is fed back through yet another condenser pump to the boiler to be regenerated into steam.
