A method for supplying a gaseous medium to a fluidized bed boiler through several pipes of a pipe grate. An active area of the grate is adjusted with a pipe-specific control included in at least some of the pipes of the pipe grate. A supply of gaseous medium to the pipe grate takes place in the active area. The active area of the grate is reduced by forming at least one inactive bed area that is out of use.
