An electric power generation system has a regulated vacuum ejector for recirculating the fluid fuel stream. The system includes a fuel cell stack, a pressurized fuel supply having a pressure control valve for regulating the pressure of the fuel supply, a vacuum ejector interposed between the fuel supply and the stack fuel stream inlet, a pressure transducer interposed between the ejector discharge outlet and the stack fuel stream inlet, and a pressurized oxidant supply with a pressure transducer. The ejector suction inlet is fluidly connected to the fuel stream outlet of the fuel cell stack. The fuel stream pressure transducer transmits a signal to the pressure control valve to adjust the pressure of the fuel supply when the detected pressure of the fuel stream deviates from a predetermined value. The oxidant stream pressure transducer transmits a signal to the pressure control valve to adjust the pressure of the fuel supply when the detected pressure of the oxidant stream changes. The system is load-following to maintain uniform fuel stream pressure and recirculation ratio over a broad range of operating conditions. The system also maintains a balance between the pressure of the fuel stream and the pressure of the oxidant stream.

An integrated fuel cell power generation system comprises a fuel cell stack having a humidification section and an electrochemically active section. The humidification section imparts water vapor to an inlet hydrogen containing fuel stream and an inlet oxygen containing oxidant stream. The electrochemically active section comprises fuel cells for promoting the electrocatalytic conversion of the humidified fuel and oxidant streams to electric current and product water. The electrochemically active section also includes a coolant water stream for absorbing heat generated in the active section. The system includes a heat exchanger for removing heat from the coolant water stream exiting the active section, a water separator for removing water from the oxidant stream exiting the fuel cell stack, and a coolant reservoir for receiving the removed water stream from the water separator and from the heat exchanger. The coolant water stream is drawn from the coolant reservoir.

This invention discloses systems, apparatuses and methods for drying or dehydrating high moisture content feedstock to dry or low moisture products. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel and wherein the processing unit forms the dried material from the dryer vessel into granules, pellets, flakes or other desired form for the final product. The systems, apparatuses and methods of this invention also provide for prevention of release of HAP, including VOC, emissions from manufacturing facilities in conjunction with or independent of the above treatment of high water content feedstock.

This invention discloses systems and methods for conversion of manure to novel fertilizer and/or soil builder products useful as input for organic farming operations. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel. The dryer vessel receives the manure for contact with the turbine exhaust gases to convert the manure to a dry material, which is passed to the processing unit where it is formed into granules, pellets or other desired form for the final dry fertilizer product. The method comprises drying, heating and converting the manure to form novel self binding fertilizer and soil builder type products for organic farming and other uses.

This invention discloses systems and methods for control of a gas turbine or a gas turbine generator, where the gas turbine is connected to a dryer vessel in which gas turbine exhaust gases are used to heat treat a material in the dryer vessel. The control system comprises one or more sensors for temperature, moisture and/or flow rate in the dryer vessel and/or of the material inside, entering and/or exiting the dryer vessel and a controller responsive to the sensor for controlling the fuel and/or air flow into the gas turbine. This control system and method enables providing the appropriate heat output from the gas turbine to meet the process heat required for the desired material treatment. Optionally, the gas turbine can be a liquid fuel turbine engine, or a reciprocating engine can be substituted for the turbine engine.
