摘要： The present invention discloses a magnetohydrodynamics power system which utilizes low temperature heat source. Variable control of the operation of the system, along with determining configurations for specific cases, are made possible by selecting the refrigerant, liquid metal circuit geometry, and by adjusting the system condensing pressure and/or temperature. Adjustable condensing pressure and/or temperature allows the system to react to changing ambient temperature and maximize power output. Adjusting condensing pressure and/or temperature of the system is made possible with a variable condenser pressure controller. The variable condenser pressure controller allows utilization of the physical properties of the refrigerant over a wide range of condensing temperatures/pressures, including pressures in the vacuum range. Meanwhile rare earth permanent magnets in paired Halbach arrays are used in the magnetohydrodynamics generator to augment the magnetic field, and a series electrode connection is made possible to achieve a high voltage output.

摘要： A system for carbon dioxide removal from product from a direct contact steam generation system is provided. The system comprises a direct contact steam generation system, a pressurized heat recovery system, and a CO2 separation system, wherein the direct contact steam generation system converts a gaseous, liquid or solid fuel, in the presence of oxygen, using a moderate water, to produce a mixed vapour stream to be then led into the pressurized heat recovery system to produce a partially condensed product, which is led into the CO2 separation system to reduce the CO2 content to produce a CO2-lean liquid product, and the pressurized heat recovery system utilizes latent heat of the mixed vapour stream to produce a lower pressure vapour stream from the CO2-lean liquid product exiting the CO2 separation system.

摘要： A system using hybrid Rankine cycles is provided. The system includes a first Rankine cycle system using a first working fluid, the first system producing exergy loss and residual energy from at least one of turbine extraction, turbine condensation and boiler flue gas; and a second Rankine cycle system using a second working fluid to recover the exergy loss and residual energy. The second working fluid comprises a first stream and a second stream, wherein the first stream exchanges heat with the first system via at least one first heat exchanger, and the second stream exchanges heat with the first system via the at least one first heat exchanger and at least one second heat exchanger. A turbine of the first system is configured to allow the first working fluid to exit at a sufficiently high pressure and temperature to provide heat to the second system instead of expanding to a low pressure and temperature and discharging heat to ambient using a condenser.
