Abstract (en)

[origin: FR2765670A1] The invention concerns a method for producing heat, in a reactor (1) with fluidised bed (7), by combustion of fuels with low calorific value, whereby a fuel with low degree of moisture, and therefore with low calorific value and a secondary fluid are simultaneously introduced in the reactor. The initial combustion conditions are adjusted to ensure autothermal combustion, i.e. in conditions of combustion temperature and retention time of the combustion gases at this temperature observing current regulations, for a reference fuel which is the fuel having the highest degree of moisture that can be used. As secondary fluid, an endothermal fluid is used and the respective flow rates (Q1, Q2) of the exothermal fuel and the secondary endothermal fluid are then adjusted so as to vary their proportions to maintain the combustion temperature constant and the oxygen content in the fumes as low as possible.
