<P>PROBLEM TO BE SOLVED: To stably burn in a gas turbine combustor, even when the calorie of calorie adjusting gas from a plant is suddenly largely varied. <P>SOLUTION: This fuel gas control device includes a main control part 110 for adjusting a flow rate of COG sent into a main fuel gas line 20 by a heat increase gas adjusting valve 31 so that unit calorie of fuel gas flowing in a gas turbine 10 approaches preset calorie, an operation state acquiring part 131 for acquiring an operation state of a coke factory 60, a calorie time characteristic estimating part 132 for estimating a calorie time characteristic of the COG corresponding to the operation state acquired by the operation state acquiring part, by referring to information of indicating the relationship between various operation states of the coke factory and a unit calorie time characteristic of the COG, and a correcting part 133 for correcting valve opening of the heat increase gas adjusting valve 31 determined by the main control part 110 so as to restrain a variation in the unit calorie of the fuel gas based on a calorie variation in the COG indicated by the calorie time characteristic. <P>COPYRIGHT: (C)2013,JPO&INPIT |
