The present disclosure relates generally to electric heating systems and methods for gas turbine engines or jet engines. The systems and methods particularly relate to one or more electric heating elements within a combustion chamber of a gas turbine engine or within a combustion chamber and/or within an afterburner of a jet engine. The combustion chamber and/or the afterburner may be configured to use one or more electric heating elements to produce heated gas. The gas turbine engine or the jet engine may be further configured to use heated gas to generate electrical or mechanical power.
The generation of power is fundamental to modern society. Currently, electrical power is primarily generated by electromechanical generators driven by heat engines fueled by nuclear fission or fuel combustion. Most modes of transportation are powered by engines fueled by electricity or fuel combustion. However, a major source of global warming is the use of fossil fuels in the production of electricity and in powering modes of transportation.
The majority of power plants around the world utilize fossil fuel, nuclear fission and biomass to boil water thereby creating extreme heat, steam and pressure. Fossil fuel is expensive, unsustainable and contributes to global warming. Examples of the effects of global warming can be found in Australia with the bleaching of the Great Barrier Reef, the rising of sea water and the warming of the planet. Also, the warming of the earth has led to larger and stronger hurricanes in recent years.
Liquified Natural Gas (LNG) is methane gas that can leak into the atmosphere prior to combustion with an effect worse than carbon dioxide. Methane is a particularly potent greenhouse gas and the fracking operations utilized to extract the natural gas with hydraulic fracturing can contaminate groundwater supplies. The use of heavy fuel oil to power cruise ships and cargo vessels is both less expensive and more damaging to the environment. This type of fuel for maritime shipping adds sulfur emissions in the atmosphere, resulting in acid rain. Automobiles, trucks, buses, trains, helicopters, propeller driven airplanes and jets all contribute to global warming.
Some aspects of the present disclosure provide an improved solution to the aforementioned problems. Particularly, one or more aspects of the present disclosure include less environmentally damaging gas turbine engine or jet engine systems and methods for producing electricity and/or powering modes of transportation. In certain embodiments, the presently disclosed gas turbine engine or jet engine systems and methods utilize electric heating elements within a combustion chamber of a gas turbine engine or within a combustion chamber and/or the afterburner of a jet engine to supplement or replace the heat traditionally generated by combustion of fuel. Accordingly, the presently disclosed systems and methods may operate more efficiently by producing greater amounts of electricity and power using standard levels of fuel. Alternatively, the presently disclosed systems and methods may generate standard amounts of electricity and power using lower levels of fuel or without fuel.
