Operating guide system of coal gasification plant and apparatus and method therefor

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 slag attributes information includes coal conversion temperature (° C.), total slag thickness (mm), liquidus slag thickness (mm), average slag viscosity (poise), and muffle length versus slag thickness {%) of the selected fuel.
