A boiler starting system for starting a boiler which has a superheater and at least two reheaters. The boiler starting system has a steam extracting line for extracting the steam from the steam inlet side or an intermediate portion of the superheater, and a steam supply valve by which the extracted steam is supplied to the reheaters. The flow rates of steam through the superheater and each reheater are controlled independently to realize optimum steam temperature rising characteristics, without requiring increase in the capacities of valves and other elements of the starting system.
