A combined cycle dual closed loop electric generating system, having a gas turbine assembly (having a combustion chamber, a compressor, a first pump, a first driveshaft, a gas turbine and a first generator) and a steam turbine assembly (having a second pump, a second driveshaft, a steam turbine and a second generator). The first portion of the working fluid circulates through the gas turbine assembly and a first heat exchanger. The second portion of the working fluid circulates through the steam turbine assembly and the first heat exchanger. The first heat exchanger transfers a first heat energy from the gas turbine loop to the steam turbine loop. The gas turbine assembly generates a first portion of an electric output. The steam turbine assembly generates a second portion of the electric output.

Hydrogen boilers with no measurable NOx emissions. In some versions the fuel is a ratio of already mixed hydrogen and oxygen, ratio of pre-mixed hydrogen and oxygen, or the fuel comprises hydrogen and the burner also contains a separate nozzle for introducing a ratio of oxygen. In some versions, these ratios are stoichiometric between hydrogen oxygen. Some versions show burner systems that monitor the combustion process, which is a condensing process, and have hydrogen oxygen pilots and ultraviolet flame detectors. These hydrogen boilers can supply all the process steam needed by a system or can supply part of the process steam needed by a system.

A device and method for generating electrical energy from hydrogen and oxygen, includes a combustion engine, a heat recovery steam generator connected into the exhaust gas duct of the combustion engine, wherein the heat recovery steam generator has only one pressure stage. An H.sub.2O.sub.2 reactor is provided to which steam from the heat recovery steam generator, water, oxygen and hydrogen are fed, such that, in the H.sub.2O.sub.2 reactor, a reaction of oxygen and hydrogen forms steam, the water that is introduced is evaporated, additional steam is generated, the resultant superheated steam is fed to a steam turbine, and a generator connected to the steam turbine provides an electric power. High-pressure feed water is injected from the heat recovery steam generator into the H.sub.2O.sub.2 reactor via a line to control the reaction in the H.sub.2O.sub.2 reactor in a targeted manner and set the steam exit temperature from the H.sub.2O.sub.2 reactor.

Modern thermal power plants based on classical thermodynamic power cycles suffer from an upper bound efficiency restriction imposed by the Carnot principle. This disclosure teaches how to break away from the classical thermodynamics paradigm in configuring a thermal power plant so that its efficiency will not be restricted by the Carnot principle. The power generation system described herein makes a path for the next generation of low-to-moderate temperature thermal power plants to run at significantly higher efficiencies powered by renewable energy. This disclosure also reveals novel high-performance power schemes with integrated fuel cell technology, driven by a variety of fuels such as hydrogen, ammonia, syngas, methane and natural gas, leading toward low-to-zero emission power generation for the future.

A method of oxy-combustion includes providing an electrolyzer feedstock to at least an electrolyzer cell; separating the electrolyzer feedstock into a hydrogen feedstock and an oxygen feedstock using the at least one electrolyzer cell; combusting a first feedstock derived from the hydrogen feedstock and a second feedstock derived from the oxygen feedstock in a furnace; controlling one or more of a second feedstock composition or a pressure in the furnace; and recycling an exhaust steam from the furnace, wherein at least one portion of exhaust steam from the furnace is recycled in at least one of a steam feedstock and the electrolyzer feedstock.

In a clean boiler with steam conversion and hydrogen/oxygen pre-blending, the clean boiler comprises two identical boiler bodies integrated to form a single entity. The clean boiler comprises two slim cavities, four water-containing chambers and four combustors, which is heated at wide faces and generates steams rapidly. The boiler comprises an integrate body containing two independent boiler bodies (1), and each of the independent boiler bodies (1) contains an independent boiler chamber (19). A steam conversion and transformation system is simultaneously provided for introducing a part of steam into the independent boiler chamber (19). High temperature of the boiler chamber (19) is utilized to promote a decomposition of the steam into H.sub.2 and O.sub.2. Water formed by H.sub.2 and O.sub.2 is utilized as a fuel to provide a self-sustaining combustion and heating, thus reducing a dependence on a primary energy source, reducing carbon emissions and protecting the environment.

The present invention provides an infrared hydrogen/oxygen combustor. The structure of the combustor includes a sinus ring (1). A surrounding foot (12) of the angle-shaped sinus ring (1) wraps a material-containing basin (14). A first small tube (16) and a second small tube (7) are connected the material-containing basin (14) and the angle-shaped sinus ring (1). Water solution (3) is contained in the material-containing basin (14). A straight-hole ceramic water-absorbing board (5) is provided on the upper part of the water solution (3), a spacing ring (6) is provided above the side of the material-containing basin (14) and in the upward ring of the angle-shaped sinus ring (1), a two-stage material-containing box (9) with a separated brake is provide on one side of the angle-shaped sinus ring (1). The technical scheme of the invention reduces the production cost, the pollution and protects the environment.

A method of and apparatus for producing electricity, hydrogen gas, oxygen gas, pure water using a geothermal heat are disclosed. A low voltage (such as less than 0.9V) is applied to a prepared solution containing hydrogen generating catalysts to generate hydrogen and oxygen. The hydrogen and oxygen are used to drive a gas turbine to generate electricity. The oxygen and hydrogen are combusted to generate heat and pure water. This process is advantageous in many aspects including desalinating salt/sea water using geothermal heat.
