摘要： A gas turbine cogeneration system includes a denitration control part for outputting to a denitration device a control command to set the amount of NOx emissions at a heat recovery steam generator outlet not more than a boiler outlet target value. The denitration control part is configured to generate the control command with reference to at least a first addition amount of a reducing agent obtained by calculation based on a NOx parameter which is a parameter correlated with the amount of NOx emissions at a turbine outlet.

摘要： A gas turbine cogeneration system includes: a gas turbine; a first fuel supply facility for supplying a first fuel to the combustor; a second fuel supply facility for supplying a second fuel with a calorific value per mass lower than the first fuel; a heat recovery steam generator for generating steam using exhaust gas discharged from the turbine; a steam supply line for supplying steam discharged from the heat recovery steam generator to a steam consumer; a steam extraction line for supplying steam extracted from the steam supply line to both a head end side of the combustor and a turbine side of the combustor; and a fuel control part for controlling the first and second fuel supply facilities so that the amount of the first fuel decreases and the amount of the second fuel increases with a decrease in extraction amount of steam by the steam extraction line.
