Description
- This non-provisional patent application is based on provisional patent application Ser. No. 60/840,786 filed on Oct. 28, 2006.
- Portable generators for producing electricity are typically powered by combustion engines fueled by gasoline or diesel. Combustion engine powered portable generators are known to be noisy (i.e. loud) and are not fuel efficient. For this reason, portable generators powered by combustion engines are primarily used for emergency power situations when more efficient conventional power sources are unavailable. Additionally, gasoline and diesel powered combustion engines are considerably heavy and bulky. This adds to the overall size and weight of portable generators, making them difficult to transport when used in mobile field operations.
- Accordingly, there remains an urgent need for a fuel efficient portable generator that is relatively quiet, compact in size, lightweight and easy to transport. Further, there is a need for a portable, fuel efficient generator that operates on multiple fuel types, including a mixture of different fuel types. Finally, there is a need for a portable, fuel efficient generator that uses heat regeneration for greater efficiency.
- The present invention provides a heat regenerative mini-turbine generator in a compact, lightweight unit. The unit includes a steam turbine connected to a central shaft that drives a high pressure pump, a high efficiency generator and a blower. An igniter burns fuel exiting a fuel injector to generate heat in a cyclone combustion chamber. Water pumped through coils is heated in the combustion chamber to produce steam energy to drive the turbine. Exhaust steam is directed through a centrifugal condenser having an arrangement of flat plates to condense the steam to a liquid state. The turbine drives the generator, through the connected shaft, to generate electric power. It is necessary to drive the generator at a high rpm to achieve the lightweight and small size. However, it is known that turbines in small sizes have poor efficiency. The use of heat regeneration helps this deficiency. The turbine heat exchanger, condenser and re-heaters are all contained in one small package. The unit is water lubricated and operates in a closed loop system. According to several preferred embodiments, the generator unit operates in a compact envelope at weight of approximately 10-25 lbs. The unit size can be scaled up or down to accommodate different power output requirements.
- For a fuller understanding of the nature of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:
-
FIG. 1 is a top plan view, shown in partial phantom lines, illustrating the heat regenerative mini-turbine generator of the present invention; -
FIG. 2 is a side elevational view, in partial cross-section, showing the main component parts of the heat regenerative mini-turbine generator; and -
FIG. 3 is an isolated view of a steam ejector nozzle fitted to a turbine housing for ejecting a pressurized flow of steam against a cupped perimeter of a turbine wheel to forcibly drive rotation of the turbine wheel and a central shaft. - Like reference numerals refer to like parts throughout the several views of the drawings.
- Referring to the several views of the drawings, and initially
FIG. 2 , the heat regenerative mini-turbine generator is shown and is generally indicated a 10. - The
generator 10 is supported on abase 12 that may includefeet 14 on the bottom for supported engagement on a floor, ground or counter surface. Afuel tank 16 rests on the top of the base. In a preferred embodiment, thefuel tank 16 is circular (i.e. donut shaped) to provide an open central area above the base that accommodates acentrifugal blower 22 and analternator 20. Afill spout 18 with acap 19 extends upwardly from the fuel tank to facilitate refilling of fuel. - A
condenser chamber 30 sits above thefuel tank 16 andalternator 20 and contains acentrifugal condenser 32 and acondensate collection pan 36 at the bottom of the condenser chamber. The centrifugal condenser has a spaced arrangement ofcondenser plates 34 that present a large surface area for maximizing heat transfer within a relatively compact space. Asight gauge 38 on the exterior of the condenser chamber indicates a working fluid level (i.e. water level) within thecondensate collection pan 36. Water can be added through afill spout 37 at the top of the site gauge by removing apressure relief cap 39. When a desired working fluid level is indicated in thesight gauge 38, thepressure relief cap 39 is replaced on thefill spout 37. - A
fuel pump 40 pulls fuel from thefuel tank 16 and directs a supply of fuel throughhose 42 leading tofuel injector 44. Thefuel injector 44 directs a spray of fuel past anigniter 46 to burn the sprayed fuel. The burning fuel is directed into acyclone combustion chamber 50 that surrounds atube bundle 54. Anigniter coil 48 connects to theigniter 46 and is powered by a battery (not shown). Theblower 22 directs air flow fromair intake 58 on thebase 12 of the generator through thecondenser chamber 30, about the exterior of thecentrifugal condenser plates 34. A portion of the air flow (approximately 20%) from theblower 22 is directed toair duct 60 leading to thecyclone combustion chamber 50, thereby providing sufficient airflow to promote combustion of the fuel. The directed airflow into thecyclone combustion chamber 50 helps to circulate the heat around the circular combustion chamber so that hot gases from combustion circulate around and over thetube bundle 54. Thecyclone combustion chamber 50 is surrounded by an insulated wall structure, including an insulatedcover 64 and an insulated central section 65 partially surrounding aturbine housing 70. Theturbine housing 70 is centrally positioned above thecentrifugal condenser 32 and contains aturbine wheel 72. Thecentral shaft 76 is fixed to the center of theturbine wheel 72 and is supported onbearings 78. Theshaft 76 extends downwardly from theturbine wheel 72 and into driven engagement with thealternator 20 andblower 22 at the lower end. Rotation of theshaft 76 drives theblower 22, thealternator 20 and acentrifugal water pump 80 in the bottom of thecondensate collection pan 36. The water pump 80 directs a flow of water to bypass governor 84. At normal operating pressure, water flow is directed toheat exchanger 86 at the top of thecentrifugal condenser 32 for pre-heating the water. From theheat exchanger 86, the water flow is directed to aconduit 87 leading to asplitter valve 88 at the top center of the combustion chamber. Thesplitter valve 88 directs the water flow through thetube bundle 54 leading to multiplesteam ejector nozzles 90. In a preferred embodiment, the splitter valve splits into fourseparate tubes 92 in thetube bundle 54, with eachtube 92 leading to one of foursteam ejector nozzles 90. In thetube bundle 54, within thecyclone combustion chamber 50, the pre-heated water is heated to produce steam which is directed to each of thesteam ejector nozzles 90. Thesteam ejector nozzles 90 are fitted to theturbine housing 70 and are arranged at an optimal angle and position to direct the ejected steam into cup shapedmembers 73 about the periphery of theturbine wheel 72. The force from the ejected steam drives theturbine wheel 72 to rotate theshaft 76. When the turbine wheel RPMs get above normal operating speed (i.e. too high), the increasing pressure of water flow from thewater pump 80 causes a valve member in thebypass governor 84 to be operated to a bypass position, causing water flow to bypass thenormal passage 85 leading to theheat exchanger 86 and, instead, going to a conduit 94 leading to theturbine housing 70. In the bypass position, the pressurized water flow is directed into the turbine housing and against theturbine wheel 72, with the impinging force of the pressurized water flow against the flat face of theturbine wheel 72 having the effect of slowing the turbine wheel, and, thereby, slowing the RPMs to a normal operating speed. - Air flow through the
condenser chamber 30 fromblower 22 is exhausted through coolingexhaust port 96. Combustion gases within the cyclone combustion chamber are exhausted throughexhaust port 98 on the top of the cover. - An
electric control panel 100 includes an ON/OFF switch 102 to start and stop operation of the generator. Upon initial start up, the ON/OFF switch 102 is operated to energize thealternator 20. During startup, thealternator 20 is motorized, using power from the battery (not shown) to turn theshaft 76 andturbine wheel 72. This allows for initial operation of theblower 22,water pump 80 andfuel pump 40. Thefuel pump 40 then directs the fuel supply to theinjector 44 andigniter 46 assembly to generate hot gases in thecyclone combustion chamber 50, while thewater pump 80 directs water flow to thetube bundle 54. Once steam is produced, theturbine wheel 72 is driven by the ejected steam and thealternator 20 switches from start up mode to normal alternator operation. - A
voltage regulator 104 on the side of the unit connects to thealternator 20. Thevoltage regulator 104 provides DC voltage atconnection terminals - While the present invention has been shown and described in accordance with a preferred and practical embodiment, it is recognized that departures from the instant disclosure are contemplated within the spirit and scope of the invention which, therefore, is not to be limited except as defined in the following claims, as interpreted under the doctrine of equivalence.
