摘要： The invention provides a gas burner for burning a fuel gas using fuel staging, said gas burner having a center line A and comprising:
- a primary fuel gas discharge opening (2) for introducing a first fraction of said fuel gas as primary fuel gas into a primary flame region (P) on said center line A for in operation fuelling a primary flame;
- a series of main fuel gas discharge openings (3) for introducing a second fraction, larger than said first fraction, of said fuel gas as main fuel gas at a main flame region (M) downstream around said primary flame for in operation fuelling a main flame;
- a series of exhaust gas return discharge openings (4) extending in said gas burner for introducing recirculated exhaust gas around said primary flame region (P) upstream of said primary flame for in operation introducing said exhaust gas into said main fuel before it ignites by said primary flame.

摘要： Disclosed are a combustor for fuel combustion and a combustion method therefor. The combustor comprises a primary oxidant-fuel delivery assembly, a secondary oxidant delivery assembly, and a tertiary oxidant delivery assembly. The secondary oxidant delivery assembly and the tertiary oxidant delivery assembly are provided on the same side of the primary oxidant-fuel delivery assembly, and the secondary oxidant delivery assembly is located between the tertiary oxidant delivery assembly and the primary oxidant-fuel delivery assembly. The present invention combines the staged combustion and dilution combustion technologies, such that the combustor has a wide flame adjusting range, realizing adjustment of the flame combustion position, flame speed range, flame local atmosphere and flame length, effectively reducing the generation of NOx, and also achieving high heat transfer efficiency.

摘要： The present invention relates to a system (1) for conversion of energy in a residual gas generated in an industrial process. The system (1) of the present invention comprises a combustion chamber (2) having a fuel inlet (3) configured to receive a flow of residual gas for combustion in the combustion chamber (2). The combustion chamber (2) further comprises an air inlet (4). The system (1) according to the present invention comprises a Stirling engine (5) configured to convert heat from the combustion chamber into mechanical energy, the Stirling engine having a heat exchanger (6) having a cross-section, wherein at least a portion of the heat exchanger (6) extends into the combustion chamber (2). According to the present invention, the system (1) further comprises a residual gas duct (7) being arranged for transporting the residual gas at atmospheric or near atmospheric pressure and an air duct (8) being arranged for transporting air at atmospheric or near atmospheric pressure. The system (1) of the present invention further comprises a gas diffusion chamber (9) comprising a residual gas inlet (10) through which the residual gas enters the gas diffusion chamber (9) from the residual gas duct (7), and a residual gas outlet (11) being in fluid communication with the fuel inlet (3) of the combustion chamber (2), wherein the residual gas is transported in a diffusion direction from the residual gas inlet (10) to the residual gas outlet (11). The gas diffusion chamber (9) has such a shape that the flow of residual gas at the fuel inlet (3) is substantially laminar and has a symmetric velocity profile.
