PROBLEM TO BE SOLVED: To provide a start control device and method of a variable pressure once-through boiler capable of shortening a boiler starting time even when a boiler recirculation pump is not used, determining the boiler starting time constant to some degree, and easily estimating the time to achieve a power generating state to supply the power at a desired time. SOLUTION: An economizer inlet water supply temperature is detected by a water supply temperature detector 21, and a reference fuel flow rate command signal is corrected on the basis of a correction signal output from a fuel flow rate corrector 22 to control the fuel supply to the boiler 5.
