Abstract
A combined cycle coal gasification power plant includes a coal gasifier which generates low BTU coal gas for consumption by a gas turbine. Before being applied to the gas turbine, the coal gas is passed through a clean-up system which removes undesirable constituents from the coal gas. Efficient operation of the clean-up system requires that a predetermined discharge pressure of clean coal gas leaving the clean-up system must be maintained. A control system controls the coal gasifier according to either one of the discharge pressure of clean coal gas and the turbine power output requirement while maintaining the clean coal gas discharge pressure and power output at predetermined values.
Claims31
A power plant, comprising:
- a coal gasification plant;
- said coal gasification plant being effective to produce a gas pressure of coal gas;
- a gas turbine effective to burn at least said coal gas and to produce an output power in response thereto;
- a coal gas plant controller responsive to a selectable one of said gas pressure and said output power for controlling feed of materials to said coal gasification plant, said coal gasification plant producing said gas pressure in response to said feed of materials;
- and
- a gas turbine plant controller responsive to the other of said gas pressure and said output power for controlling feed of at least said coal gas to said gas turbine.
A power plant of the type including a coal gasification plant effective to produce a coal gas at a pressure, a gas clean-up system effective to clean contaminants from said coal gas to produce clean coal gas, at least one gas turbine effective to burn said clean coal gas and to drive a load at a predetermined output power, comprising:
- a control system;
- first means in said control system for controlling said coal gas plant in response to a selectable one of said pressure and said output power;
- and
- second means in said control system for controlling said gas turbine in response to the other of said pressure and said output power.
