Claim 11:
12. An operating guide system of a plant utilizing coal gasification, the operating guide system comprising:
an input interface;
a screen;
a processor; and
a storage, connected with the processor by a bus, storing one or more programs configured to be executed by the processor, the one or more programs including instructions for:
receiving, by the input interface, an input selecting a fuel having basic attributes information and slag attributes information;
determining, before the plant is started, gasification suitability type information of the selected fuel, based on a first comparison between the basic attributes information of the selected fuel and a first predetermined reference value and a second comparison between the slag attributes information of the selected fuel and a second predetermined reference value;
storing the gasification suitability type information;
generating performance analysis information of the plant by analyzing, while the plant is operated using the selected fuel, gasifier performance information and synthesis gas cooler performance information of the plant;
generating an operation guide information indicating operation control values for the operation of the plant based on the generated performance analysis of the plant; and
displaying, on the screen, the operation guide information with the operation control values,
wherein the determining gasification suitability type information comprises outputting the determined gasification suitability type information into a plurality of fuel types including a first fuel type being a coal which may be used without being added with flux or another coal, a second fuel type being a coal which may be used when the flux is added, a third fuel type being a coal which may be used when mixed with another coal, and a fourth fuel type being a coal which is not suitable for the gasification and then classifying the selected fuel into one of the plurality of fuel types.
