A power plant has two fluidized beds, one of the fluidized beds being used for generating main steam and the other being used for generating reheated steam. Further, the power plant includes a control apparatus for controlling the main steam by adjusting the fuel flow for the main steam generating fluidized bed and the fuel flow for the reheated steam generating fluidized bed so that each of the main steam temperature and the reheated temperature is maintained at a respective predetermined value.
