A liquid and/or gaseous fuel is burned in a tubular combustion chamber which has at least one baffle wall therein with a central aperture therethrough, comprises directing the fuel into the combustion chamber in a stream adjacent the baffle so as to cause it to flow through the aperture of the baffle and directing combustion air into the combustion chamber around and substantially parallel to the fuel stream so as to cause a portion of it to be directed against the baffle plate and whirl around adjacent the aperture and a further portion to pass directly through the aperture and into the whirling stream so as to provide a turbulent air stream which intermixes with the fuel both downstream and upstream of the baffle, igniting the fuel and air as it intermixes, and directing a separate combustion air stream into the intermixed fuel and combustion air on the opposite downstream side of the baffle. In addition, the secondary combustion air supply may be admitted upstream of the baffle and the air streams may advantageously be directed radially and tangentially inwardly. |
