摘要： A method of retrofitting a power generation system having a coal-fired steam boiler, a steam turbine system, and a condenser comprising installing a hydrogen-fired combustion system therein having the step of replacing the coal-fired steam boiler with a hydrogen-fired combustion system such that a steam flow generated by the hydrogen-fired combustion system is directed to the steam turbine system. Another method of retrofitting a power generation system has the steps of installing a hydrogen-fired combustion system to receive the steam flow, a hydrogen stream, and an oxygen stream, and to produce a super-heated steam flow therefrom; and installing a new steam turbine system capable of receiving and expanding said super-heated steam flow and directing said expanded super-heated steam flow to at least a portion of said original steam turbine system.

摘要： A steam turbine plant partially utilizes a hydrocarbon fuel such as an LNG as a fuel to improve the efficiency of the plant. A steam turbine plant includes a boiler, a steam turbine, a feedwater system, and a superheating combustor. The boiler generates steam, and the steam turbine is driven by the steam generated in the boiler. The feedwater system recovers the steam exhausted from the steam turbine and supplies the steam to the boiler as a feedwater. The superheating combustor is provided between the boiler and the steam turbine, wherein fuel originated from hydrocarbon fuel and oxidizer are mixed with the steam generated in the boiler and combusted in the superheating combustor to increase the temperature of the steam.

摘要： A method which develops a supercritical combustion chamber environment and combines fumigation and water conversion to superheated steam to effect greater fuel efficiency and reduce exhaust gas pollutants from a compression ignition engine. The invention utilizes the fumigant method by combining two gases (DME and heptane) which autoignite prior to the injection of the liquid water. This pre-combustion of the fumigant gases combined with the engine's compression of the combustion chamber gases is managed to attain a supercritical combustion chamber environment into which the liquid water is injected. This targeted supercritical combustion chamber environment causes the water to become a superheated steam, resulting in significantly greater efficiency and negligible exhaust gas pollutants resulting from the steam engine.

摘要： Provided is a heat generating arrangement and a method for generation of heat to be used in a heat consumer. The heat generating arrangement uses combustion of aluminium and hydrogen to raise the temperature of superheated steam inside the heat generating arrangement. The heat in the superheated steam can thereafter be used in a heat consumer, such as a heat exchanger.
