ABSTRACT:
A multibed fluidized boiler having at least two fluidizable beds, in which conventional fuel, for example coal, is supplied to the first bed and in which the combustion of this fuel takes place in the first bed and in the following bed. An alternative fuel, such as wood chips, waste wood or paper, or combustible refuse, is adapted to be supplied to the second bed in order to be burnt there, thus obtaining a simplified fuel feeding to the second bed and increased protection against clogging of the nozzles for the supply of gas from the first bed to the second bed.
