Abstract
A fuel gas heating control equipment in accordance with the present invention is provided with a gain-determining portionand a time-constant-determining portionwhich determine values of a gain and a time constant to be used for PI calculations being performed by a PI calculation portionThe gain-determining portionspecifies a small time constant for the PI calculation portionduring load fluctuations when the generator output increases, and specifies a large time constant for the PI calculation portionwhen the generator output reaches the maximum output. In consequence, during load fluctuations, responsiveness is good and a rapid change in temperature can be followed, so that a fuel gas temperature will not fluctuate in response to a slight change in temperature at the maximum output, thereby achieving a stable fuel gas temperature.
