Abstract (en)

[origin: WO2011131880A1] Fuel-fired furnace and a method for operating it, in which method: a main oxidizing agent is injected at a controlled flow rate into the combustion chamber (2) of the furnace; the combustible material is burnt in the combustion chamber (2) with the main oxidizing agent, producing thermal energy and flue gases (6) at a temperature higher than 600oC; the flue gases (6) are removed via an exhaust duct (13), said removed flue gases (6) possibly containing residual materials that could be oxidized, the exhaust duct (13) being equipped with an inlet (14) for a diluting oxidizing agent downstream of the combustion chamber (2); the residual materials that could be oxidized are burnt with the diluting oxidizing agent by means of a flame (12) at the inlet (14) for the diluting oxidizing agent; the flame intensity inside the exhaust duct (12) is detected; and the flow rate at which the main oxidizing agent is injected into the combustion chamber (2) is controlled according to the detected flame intensity.
