Abstract (en)
Circulating fluidized bed reactor including a lower region (3) with a fluidization grating (11), injection of primary and secondary air (12, 13) and supply of fuel (10), an upper region (2), dense internal fluidized beds (22, 23) at the top of the lower region (3), which withdraw solid materials from the internal recirculation of the reactor and send them in part into the external dense fluidized bed exchangers attached against the walls of the reactor at the internal beds (22, 23). These external exchangers expel the materials, after the heat exchange with an external fluid, into the lower region (3). Reactor with simple design benefitting from the advantages of dense external beds whilst retaining conventional construction of the lower region (3). <IMAGE>
