Abstract
A method and system for supplying fuel are provided. The fuel supply system includes a supply of a flow of fuel wherein the fuel includes an amount of moisture in a first predetermined range, a supply of a flow of gas wherein the gas includes an amount of moisture in a second predetermined range and wherein the second predetermined range is less than the first predetermined range. The fuel supply system further includes a vessel configured to receive the flow of fuel and the flow of gas, mix the flow of fuel and the flow of gas, and separate the flow of fuel from the flow of gas wherein moisture is transferred from the flow of fuel to the flow of gas.
Claims20
A fuel supply system comprising:
- a supply of a flow of fuel, said fuel comprising an amount of moisture in a first predetermined range;
- a supply of a flow of gas, said gas comprising an amount of moisture in a second predetermined range, the second predetermined range being less than the first predetermined range;
- and
- a vessel configured to:
- receive said flow of fuel and said flow of gas;
- mix said flow of fuel and said flow of gas;
- and
- separate said flow of fuel from said flow of gas
- wherein moisture is transferred from said flow of fuel to said flow of gas.
A method of operating a fuel supply system, said method comprising:
- receiving a flow of carbonaceous fuel, the fuel comprising a first amount of moisture;
- and
- mixing the flow of carbonaceous fuel with a flow of a gas such that the first amount of moisture in the fuel is reduced and a second amount of moisture in the gas is increased, the flow of gas comprising an amount of heat wherein at least some of the amount of heat is transferred to the flow of fuel during the mixing.
An integrated gasifier combined cycle power system comprising a fuel dryer configured to:
- receive a flow of fuel;
- receive a flow of fluid;
- transfer moisture from the fuel to the gas;
- and
- transfer heat from the gas to the fuel.
