    摘要： Bei einem Dampferzeugergasbrenner (1) zur Verbrennung niederkalorischer Gase, der ein Kernluftrohr (2), ein unter Ausbildung eines insbesondere ringförmigen Gasströmungsquerschnittes (5) koaxial um das Kernluftrohr (2) angeordnetes Gasrohr (6) und mindestens ein weiteres, unter Ausbildung eines insbesondere ringförmigen Sekundärluftströmungsquerschnittes (7) um das Gasrohr (6) angeordnetes Rohrelement (8) umfasst, wobei in dem Gasströmungsquerschnitt (5) erste Drallkörper (9) angeordnet sind, soll eine Lösung geschaffen werden, die es ermöglicht, einen Dampferzeugergasbrenner unter Berücksichtigung der jeweiligen Zündintensität an variierende Brenngaseigenschaften, insbesondere einen schwankenden Heizwert, anzupassen. Dies wird dadurch erreicht, dass die ersten Drallkörper (9) verstellbar angeordnet sind.

    摘要： Gas burner for burning a gas with a low calorific value, such as syngas derived from the gasification of biomass, the burner comprising a first annular zone (5) formed between the external wall (16) and an internal wall (17) of the burner substantially parallel to the external wall, a second annular zone (8) formed between the external wall (16) of the burner and the internal wall (17) downstream of the first zone, and the burner comprising a low calorific value gas supply pipe (1) substantially parallel to the axis of the burner, a primary air supply pipe (3) formed in the external wall (16) and opening into the first annular zone (5), a secondary air supply pipe (4) formed in the external wall (16) and opening into the second annular zone (8), an annular slot (6) for introducing primary air from the first annular zone (5) into the combustion zone (7), said annular slot (6) being formed between the external wall (16) and the upstream end (25) of the internal wall (17), orifices (9) for introducing secondary air from the second annular zone (8) into the combustion zone (7), said orifices being pierced in the internal wall (17), and the annular slot (6) having a shape such that the primary air is carried into the combustion zone (7) in the form of a conical sheet of air and creates an area of compression, and the orifices (9) being arranged in such a way as to allow the secondary air to swirl.

    摘要： A premix-type gaseous fuel burning system (10) for alternate or simultaneous combustion of low BTU gas (29) and normal BTU gas (27) comprises a gas supply means (35) for providing both high BTU gas (27) and low BTU gas (29) at a selected substantial velocity and a burner tube (44) for receiving the gas, whereby primary air (41) is inducted into the burner tube (44) and mixed with the gas flow. A burner head (64) comprises a long narrow rectangular structure of tapered construction that is inserted upwardly into a corresponding rectangular opening (28) in the floor (24) of the furnace (18). The opening (28) is also tapered in the same direction as the burner head (64) but with a selected annular spacing (70) between the walls of the opening (28) and the burner head (64). Means (76, 78) are provided for vertically adjusting the position of the burner head (64) within the opening (28). Secondary combustion air (62) is directed through the annular space (70) between the burner head (64) and the opening (28) in the floor (24) of a furnace (18).

    摘要： The invention relates to a burner (10) for mixing and burning of at least two combustion media (28, 38, 48), in particular combustion air and a lean gas as the gaseous fuel. The burner comprises a plurality of burner nozzles which each comprise at least three pipes (20, 30, 40) arranged coaxially in relation to each other. The pipes are at a distance from each other in the radial direction to form annular clearance ducts (39, 49) through which combustion media can be conveyed into a combustion chamber. The arrangement according to the invention results in good mixing and combustion of a plurality of gaseous combustion media.
