Abstract
A generator set employs a gas turbine which selectively uses reformed vegetable oil and fluid fuel. The generator set operates so as to supply the reformed vegetable oil to the gas turbine when a temperature of the reformed vegetable oil is higher than a predetermined temperature and when a load is applied to the gas turbine, and to supply the fluid fuel to the gas turbine when the temperature of the reformed vegetable oil is lower than the predetermined temperature or when no load is applied to the gas turbines
Claims13
A generator set for reformed vegetable oil, comprising:
- a fluid fuel tank storing fluid fuel;
- a vegetable oil tank storing reformed vegetable oil;
- a gas turbine generating electric power by consuming the reformed vegetable oil as fuel;
- a fuel supply control section fluidly connected to the fluid fuel tank, the vegetable oil tank and the gas turbine, the fuel supply control section controlling pressure of the fluid fuel supplied from the fluid fuel tank and pressure of the reformed vegetable oil supplied from the vegetable oil tank, the fuel supply control section supplying the pressure controlled fluid fuel and the pressure controlled reformed vegetable oil to the gas turbine;
- and
- first and second valves selectively supplying the fluid fuel in the fluid fuel tank and the reformed vegetable oil in the vegetable oil tank to the fuel supply control section.

A generator set for reformed vegetable oil, comprising:
- a gaseous fuel supply section supplying gaseous fuel;
- a vegetable oil tank storing reformed vegetable oil;
- a gas turbine generating electric power by a using the reformed vegetable oil as fuel;
- a fuel supply control section fluidly connected to the vegetable oil tank and the gas turbine, the fuel supply control section controlling pressure of the reformed vegetable oil supplied from the reformed vegetable oil tank, the fuel supply control section supplying the pressure controlled reformed vegetable oil to the gas turbine, and
- a booster connected to the gaseous fuel supply section, the booster pressurizing the gaseous fuel at a predetermined pressure value;
- a first valve disposed in a passage connecting the booster and the gas turbine, the first valve being selectively opened and closed to selectively supply and stop the gaseous fluid to the gas turbine;
- and
- a second value disposed in a passage connecting the vegetable oil tank and the fuel supply control section, the second valve being selectively closed and opened to selectively stop and supply the reformed vegetable oil to the gas turbine.
5 more elements
A generator set for reformed vegetable oil, comprising;
- a fluid fuel tank storing fluid fuel;
- a vegetable oil tank storing reformed vegetable oil;
- a gas turbine generating electric power by using one of the fluid fuel and the reformed vegetable oil as fuel;
- a fuel supply control section fluidly connected to the fluid fuel tank, the vegetable oil tank and the gas turbine, the fuel supply control section controlling pressure of the fluid fuel supplied from the fluid tank and pressure of the reformed vegetable oil supplied from the vegetable oil tank, the fuel supply control section supplying the pressure controlled fluid fuel and the pressure controlled reformed vegetable oil to the gas turbine;
- first and second valves selectively supplying the fluid fuel in the fluid fuel tank and the reformed vegetable oil in the reformed vegetable oil tank to the fuel supply control section;
- and
- a controller coupled to the gas turbine, the fuel supply control section and the first and second valves, the controller being configured,
- to receive a gas-turbine operation signal indicative that the gas turbine is in an operable state and a load signal indicative that a load is applied to the gas turbine, from the gas turbine,
- to receive a fuel supply condition signal indicative of a condition of the reformed vegetable oil from the fuel supply control section,
- to command the fuel supply control section and the first and second valves to supply the reformed vegetable oil when the controller determines from the fuel supply condition signal that a temperature of the reformed vegetable oil is higher than a predetermined value and when the controller receives the load signal, and
- to command the fuel supply control section, the first valve and the second valve to supply the fluid fuel when the controller does not receive the load signal.
8 more elements
