ABSTRACT:
A method and means for regulating the thermal transmission rate at a fast fluidized bed reactor, which comprises a combustion chamber, a cyclone separator and a lock between the separator and the combustion chamber. The method comprises varying heat absorption to the conductive parts of the combustion chamber through changing the particle density in the fluidized bed when altering the load and/or the kind of fuel. This imples adding of fine grain, inert particles to the bed, or alternatively removing large size particles from the bottom of the combustion chamber and fine grain particles from the lock, respectively.
