FUEL SUPPLY APPARATUS FOR TURBINE AND CONTROL METHOD THEREOF

摘要

The present invention relates to a fuel supply device for a turbine and a control method thereof. The fuel supply device for a turbine includes a biogas supply unit supplying biogas to an engine of a gas turbine; a gas supply unit supplying gas mixed with air to obtain the same quantity of heat with a heat generation rate of the biogas; and a fuel compensating unit compensating the overall fuel supply amount by controlling the pressure of the gas supplied from the gas supplying unit based on a pressure change of the biogas supplied from the biogas supplying unit. The gas is supplied to the fuel compensating unit while being mixed with air to obtain the same quantity of heat with the heat generation rate of the biogas. The fuel supplying device for the turbine and the control method thereof can obtain an effect of regularly maintaining the overall fuel supply amount to the gas turbine by using the gas mixed with air and having the same quantity of heat with the heat generation rate of the biogas in case of a change in the generation of the biogas.
