<P>PROBLEM TO BE SOLVED: To provide a fuel gasification system that stabilizes the calorific value of a combustible gas produced by gasifying a fuel while the increase and decrease of the amount of char produced being controlled even when the type or properties of fuel vary, to provide a control method and a control program that are applied to the fuel gasification system and to provide a fuel gasification combined power generating system that has the fuel gasification system. <P>SOLUTION: A control device 26 of a fuel gasification system 12 controls the supply amount of fuel to a gasification furnace 16 in accordance with the index corresponding to the calorific value of a combustible gas (the calorific value of SG), and at the same time controls the supply amount of oxygen gas to the gasification furnace 16 so that the ratio of the supply amount of oxygen gas to the supply amount of air to the gasification furnace 16 varies. <P>COPYRIGHT: (C)2013,JPO&INPIT |
