Combustion Powered Hydroelectric Sequential Turbines

Abstract

This invention is a method to extract energy from a pressurized gas in the case that the gas may be unsuitable for use in a gas turbine. The system is a gas powered liquid pump. The system expands the gas against a liquid such as water and the water then flows through a series of liquid turbines to generate power. As the gas expands the pressure decreases. The water is initially directed to a turbine designed to work efficiently with high-pressure water, and then the water is redirected to another turbine which is designed to work efficiently with lower pressure water. As the pressure of the gas and the water decreases, the turbine which most efficient for extracting the energy at a given pressure is used to extract the energy from the stream of pressurized water

1 . A method for extracting energy from a supply of pressurized gas including the steps of:
 i Expanding a gas in a chamber containing a liquid and a gas at a high pressure   ii Flowing said liquid through a valve to a liquid turbine designed to operate efficiently at said high-pressure.   iii At a predetermined lower pressure closing said valve to said high-pressure turbine and opening a valve to a turbine designed to operate efficiently at a lower pressure than said high pressure.   
   
   
       2 . A method for extracting energy as in  claim 1 , wherein said high pressure is greater than 3 atmospheres. 
   
   
       3 . A method for extracting energy as in  claim 1 , further including the step of firing a rocket engine to ignite a chamber full of particulate fuel and compressed air in order to generate pressurized gas. 
   
   
       4 . A method for extracting energy as in  claim 1  further including the step of flushing a hot air valve seal with flowing water. 
   
   
       5 . A method for extracting energy as in  claim 1  further including the step of periodically cleaning the inside of the pump chamber by filling it with an alternative gas. 
   
   
       6 . A method for extracting energy as in  claim 1  further including the step of continuously pumping and filtering the fluid in the chamber in a loop.
