Abstract (en)

[origin: WO0229326A1] The invention relates to a method for automatized combustion of solid fuel in a combustion apparatus which comprises a burner (1) which is connected to a boiler (400) and has a feeding-in opening (63, 62) for fuel and an outlet opening (3) which opens in a combustion chamber (401) inside the boiler which comprises a convection unit (402) and a flue gas pipe (407) for waste flue gases containing CO2 and not combusted O2, the combustion apparatus comprising a device (27) for feeding combustion air into the burner, and a fuel charge feeder (200, 212) for fuel provided to be driven by a motor (211), here called fuel charge feeding motor, the operation of the fuel charge feeding motor (211) being regulated by command from a control unit (300) in dependency on measured values transmitted to the control unit (300) in dependency on measured values transmitted to the control unit (300) and in dependency of the heat power the burner shall generate, and a measuring device (408) arranged for measuring the content of CO2 and or O2 in the flue gases. The invention is characterized by said measuring device (408) transmitting measuring signal to said cotrol unit (300) regarding the contents of the flue gases and that the contenets of the flue gases is regualted by means of the control unit (300) regulated the fuel charge feeding motor with reference to the values measured in the flue gases, maintaining an optimal content of the gas measured by the measuring device (408) in the flue pipe (407). The invention also relates to a combustion apparatus in which the above mentioned procedure is being applied.
