US 8196395 B2Abstract
Images(208) Claims(14)
a moveable member disposed within a cylinder device;
a mechanical linkage in communication with the moveable member;
a gas storage unit in fluid communication with the cylinder device through valving;
a control system in communication with the valving to allow compressed gas expanding within the cylinder device, to drive the moveable member;
an element in fluid communication with a liquid reservoir to introduce liquid for heat transfer with the compressed gas expanding within the cylinder device in an absence of combustion;
a second moveable member disposed within a second cylinder device and in communication with the mechanical linkage; and
a second element in fluid communication with a second liquid reservoir to introduce liquid for heat transfer with gas within the second cylinder device;
wherein the second cylinder device is selectively configurable as a compressor or as an expander, and wherein the second cylinder device is configured to be in selective fluid communication with the cylinder device.
2. An apparatus as in claim 1 wherein the element is configured to introduce the liquid as mist comprising droplets having a mean diameter of 50 microns or less.
3. An apparatus as in claim 1 further comprising a liquid separator configured to remove liquid from gas expanded in the cylinder device for containment in the liquid reservoir.
4. An apparatus as in claim 1 further comprising an electrical generator in communication with the mechanical linkage and configured to output electrical power from motion of the moveable member.
5. An apparatus as in claim 4 wherein the control system is configured to:
receive a signal, and based upon the signal, electronically control the valving to cause the compressed gas expanding within the cylinder device to drive the mechanical linkage so that the electrical generator supplies electrical power to a power supply network over a ramp up period of a generation asset.
6. An apparatus as in claim 1 wherein the mechanical linkage is configured to convert a reciprocating motion of the moveable member to shaft torque.
7. An apparatus as in claim 6 wherein the mechanical linkage comprises a crankshaft.
8. An apparatus as in claim 1 wherein the moveable member comprises a solid piston, a screw, a turbine, a multi-lobe blower, a vane compressor, a gerotor, or a quasi-turbine.
9. An apparatus as in claim 1 wherein the mechanical linkage is configured to be in selective communication with an energy source to compress gas within the cylinder device.
10. An apparatus as in claim 9 wherein the mechanical linkage comprises a rotating shaft and the energy source comprises a source of shaft torque.
11. An apparatus as in claim 10 wherein the moveable member comprises a reciprocating piston and the rotating shaft comprises a crankshaft.
12. An apparatus as in claim 9 wherein the energy source comprises a motor/generator.
13. An apparatus as in claim 1 wherein the element comprises a spray nozzle.
14. An apparatus as in claim 1 wherein the element comprises a mixing chamber configured to be in selective fluid communication with the cylinder device.
