Description Motive Fluid Generator for Power Generation
BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to an internal combustion and internally cooled steam engine and powering method to be used as a fuel efficient and environmentally friendly means of powering steam turbines and like drive assemblies.
Description of the Prior Art
A commonly sought after goal of engine powering systems is to maximize the amount of work that can be performed by a minimal amount of fuel. Additionally, it is desirous to minimize pollutants generated by these engines. For these reasons, others in the past have attempted to develop hybrid engines that combine fuel combustion and steam powering. In U.S. Patent No. 4,300,353 to Ridgway, and U.S. Patent No. 4,509,464 to Hansen, complex systems were developed to combine fuel combustion and steam powering. These engines however, include separate steam generating and fuel combusting operations, and combine their finished product to power the system. Other systems as that of Hallstrom, Jr., U.S. Patent No. 4,433,548, utilize extra energy from a first operation to provide energy for a second power stroke, thereby providing two strokes of average power. Finally, engines such as those devices by Thomas, U.S. Patent No. 4,417,447 and Thomas, U.S. Patent No. 4,783,963, inject water into individual heated power cylinders which serve as a steam boiler which provide steam for the power stroke. None of these designs, however, provide a singularly contained unit which through a single combustion process heats separately contained fuel and water, and combines the formed steam and the heated gasses formed by the fuel combustion to provide a single high-powered, easily filtered means of driving a turbine.
Applicant's invention is devised specifically to utilize a single efficient process which combines all the by-products gasses of fuel combustion, most of which would normally be wasted in
ordinary combustion processes, with the steam produced from same initial combustion of fuel and air, and thereby provide easily filtered super heated means of powering a turbine.
summary of the Invention The present invention relates to an internal combustion internally cooled steam engine and powering method to be used a fuel maximizing and environmentally friendly means of power a steam turbine. The steam engine includes a pressure cham containing a boiler concentrically positioned therein. The boil which includes water inlet means, is used to contain water to heated and includes a plurality of steam outlet apertures such th steam may escape from the boiler and into the pressure chambe Concentrically positioned within the boiler is a combusti chamber. The combustion chamber includes air and fuel inlet mea to enable a mixture of air and fuel to be sprayed therein whe they may be ignited to form hot gasses and to heat the water within the boiler. Connected to the combustion chamber is at lea one flue gas line which extends from the combustion chamber in the pressure chamber. The flue gas line includes a plurality holes therein such that hot gasses emerging from the combusti chamber may escape therethrough and mix with the steam in t pressure chamber. The hot gasses and now super heated steam with the pressure chamber is then directed towards means connected the pressure chamber, thereby resulting in the driving of a ste turbine.
It is an object of the present invention to maximize the fu used by utilizing it to heat water as well as utilizing the h gasses formed from the fuel to super heat the steam and assist driving the steam turbine. It is another object of the present invention to provide steam engine which is cost effective to construct and can perfo equivalent amounts of work as a larger steam engine.
It is yet another object of the present invention to drive steam turbine while producing minimum amounts of soot and smok and allowing that sulfur oxides formed may be easily filtered su that they do not escape into the environment.
Brief Description of the Invention
For a fuller understanding of the nature of the present invention, reference should be had to the following detailed description taken in connection with the accompanying drawings, in which
Figure 1 is a cross-sectional side view of the internal combustion and internally cooled steam engine.
Figure 2 is a cross-sectional front view along line 2-2 of Figure 1. Like reference numerals refer to like parts throughout the several views of the drawings.
Detailed Description of the Preferred Embodiment
As detailed throughout Figures 1 and 2, the present invention is directed towards an internal combustion and internally cooled steam engine generally indicated as 10. The steam engine 10 includes primarily a pressure chamber 20 wherein a boiler 30 is concentrically positioned atop support legs 84. Concentrically located within the boiler 30 is a combustion chamber 40 wherein air and fuel are ignited. The air and fuel are sprayed into the combustion chamber 40 from an air inlet conduit 42 and a fuel inlet conduit 44 which pass through the pressure chamber 20 and are connected to the combustion chamber 40. The air inlet conduit 42 and fuel inlet conduit 44 further include atomizers 45 at an end thereof such that the fuel and air will be sprayed into the combustion chamber 40. The fuel and air within the combustion chamber 40 are ignited using an ignitor 46, and cause water 35 within the boiler 30 to boil and turn to steam. The steam emerges from the boiler 30 and into the pressure chamber 20 by means of a plurality of steam outlet apertures 32 located atop the boiler 30. Additionally, hot gasses formed by igniting the fuel and air within the combustion chamber 40 pass through a pair of flue gas lines 50 which are connected to the combustion chamber 40 and extend into the pressure chamber 20. Each of the flue gas lines 50 includes a plurality of holes 52 such that the hot gasses may pass into the pressure chamber 20 and mix with the steam, thereby super heating the steam. The hot gas and super heated steam may then be filtered to remove sulfur oxides therefrom by a filtration device 80, and
function to power a turbine 90 connected to the pressure cham 20. In order to further increase the efficiency of the engine the filter 80 is placed in a conduit to the turbine 90, all which are recessed within the pressure chamber. Located about periphery of the pressure chamber 20 are a plurality of press release valves 70. Additionally, a temperature gauge 75 pressure gauge 76 are connected to the pressure chamber 20 measure the conditions therein.
In order to minimize the heat loss of the steam engine 10, pressure chamber 20 is surrounded by a layer of insulation Further, in order to maintain a constant water level which ent the boiler 30 through a water inlet conduit 38, a water level ga 85, best seen in Figure 2, passes through the pressure chamber and is connected to the boiler 30. The engine 10 can be used to produce steam mixed with f gasses, and with slight modification, steam without flue gass Accordingly, it can be used as a water heater, distillation devi or steam generator. All of these devices would incorporate same principal of having the combustion chamber 40 below surface of the fluid.
