Abstract: An energy storage and modulating system for renewable energy off-grid power generation, and a method for modulating the same. The excess electricity from a renewable energy power generation device after the electricity consumption on a demand-side is met is output to a short-term energy storage device and/or an electric energy conversion device to be converted into a combustion medium corresponding to a mid/long term energy storage device. When the renewable energy power generation devices cannot meet the demand-side electricity consumption, the electricity can be generated by modulating the electric energy stored in the short-term energy storage device and/or burning the combustion medium corresponding to the energy storage through a gas turbine power generation system, supplementing the electric energy output from the renewable energy power generation device, thereby enabling the entire off-grid power generation system supply stable energy.
Abstract: Provided is a gas turbine combustor that achieves simplified structure and reduced axial length of the entire device. The combustor includes: a combustion liner forming a combustion chamber; a fuel injector provided at a top portion of the combustion liner; and a housing chamber located upstream of the combustion chamber and housing the fuel injector. The fuel injector includes a fuel supply tube penetrating through the housing chamber and configured to supply fuel to the combustion chamber, and a guide member provided on outer side of a downstream portion of the fuel supply tube for allowing air to pass therethrough. The fuel supply tube has, in the downstream portion, a fuel injection hole for injecting fuel to the air passing through the guide member, so as to mix the fuel with the air. The guide member supplies the air and the fuel to the combustion chamber.
