Control method for gasification power generation system

摘要

{Abstract of the disclosure} A control method for a gasification power generation system comprising the steps of: inferring a syngas heating value and a syngas quantity from a 5 property and a feed rate of the carbon based fuel and the operation state of the gasifier, correcting the inferred value of the syngas heating value from the analytical values of the syngas of the instruments between the gasifier and the gas turbine 10 equipment, inferring the time lag until the syngas heating value is changed at a gas turbine equipment inlet after the feed rate of the carbon based fuel is changed from the inferred value of the syngas quantity, the volumes of the instruments, and the 15 temperature and pressure of the syngas in the instruments, and using the inferred syngas heating value to control the gas turbine equipment after the time lag. z C/) Bm Lo ~Z=) CD) CD
