Abstract
Method for combusting a solid phase fuel, where the fuel is caused, by the help of a non-pneumatic feeding element (11), to be fed to an inlet opening (11a) in a burner device (10) having a first inlet (13a) for the oxidant through which an oxidant is caused to flow via a first supply conduit (13). The first inlet (13a) for oxidant is caused to be arranged in the form of an opening surrounding the inlet opening (11a), in that the oxidant is caused to flow out through the opening (13a) with a velocity of at least 100 m/s, through a burner pipe (16) and out through a burner orifice (17) to a combustion space (18), so that the oxidant by ejector action causes the fuel to be conveyed through the burner pipe (16) and out through the burner orifice (17).
Claims18
Method for combusting a solid phase fuel, where the fuel is caused, by the help of a non-pneumatic feeding means (11), to be fed to an inlet opening (11a) in a burner device (10), where the burner device (10) is caused to comprise a first inlet (13a) for the oxidant through which an oxidant is caused to flow via a first supply conduit (13), characterised in that the first inlet (13a) for oxidant is caused to be arranged in the form of an opening surrounding the inlet opening (11a), in that the oxidant is caused to flow out through the opening (13a) with a velocity of at least 100 m/s, through a burner pipe (16) and out through a burner orifice (17) to a combustion space (18), so that the oxidant by ejector action causes the fuel to be conveyed through the burner pipe (16) and out through the burner orifice (17).
Device for combustion of a fuel in solid phase, where a non-pneumatic feeding means (11) is arranged to feed the fuel to an inlet opening (11a) in a burner device (10), where the burner device (10) comprises a supply system (12;19) which is arranged to supply oxidant to the burner device (10) via a first supply conduit (13) and a first inlet (13a) for oxidant, characterised in that the first inlet (13a) for oxidant is arranged in the form of an opening surrounding the inlet opening (11a), through which the supply system (12;19) is arranged to supply the oxidant in a stream at a velocity of at least 100 m/s, through a burner pipe (16) and out through a burner orifice (17) to a combustion space (18), and thereby to convey the fuel, by ejector action caused by the stream of oxidant, through the burner pipe (16) and out through the burner orifice (17).
