    Abstract: An original unit mixes fluids having identical or differing mass flow rates. Flowing along a partition wall (22), they pass freely around surfaces of several, adjacent, downstream, turbulent eddy generators (9). Sides (11, 13) of these bodies (9) are flush with one side of the partition (22). Between them, and angle ( alpha ) is included. The long edges of the body (12, 14) include an angle (&thetas; ) with the wall (22). The sides (11, 13) share a connecting edge (16) which is perpendicular to the wall (22), forming the leading edge. The body has a roof in two sections (1, 2), terminating at the sides (11, 13), and connecting at a edge (10). The trailing edges (5, 6) of the roof sections subtend an angle ( gamma ) with the wall (22), and lie on the opposite side of it. A base has two sections (3, 4) joining at an edge (30), and connected by the rear edges (5, 6) to the roof sections.

    Abstract: The pre-mix burner has a vortex stabilising cavity (20), formed from offset part bodies (11,12) fitting in each other, and a conical inner body (13). Input channels (11c,12c) extend upstream of the tangential air input slits (11a,12a) formed by the offset part bodies. Each input channel has at least one device (11d,12d) to cause turbulence in the air flow (23), and a system for introducing the fuel. The fuel should preferably be introduced downstream of the turbulence causing devices.

    Abstract: The fuel is introduced as a secondary current into a gaseous main current enclosed by an annular premixing duct (20) defined by an inner (21a) and outer (21b) cylinder wall. The main flow is guided by vortex generators (9,9a) which create a vortex leaving behind a residual vortex when the fuel has been completely mixed with the air of the fuel and air mixture. The annular main current duct of constant height (H) has a length (L), downstream from the vortex generators and fuel injector, which is between 5 and 20 times the height. The annular main flow duct widens into a circular main flow duct by closing the inner cylinder wall (21a).

    Abstract: The pre-mix combustion process involves using fuel (7,8) and a working gas (3,4,9) in preparation for combustion. There are at least two stages (1,2). In the first stage (1), fuel (7) and combustion air (3) with excess of air are mixed in a mixer (21). The mixture (23) thus formed is stabilised by a flame stabiliser (11) and burned. In the second stage, fuel (8), combustion air (4) and/or smoke gas (9) are mixed in a mixer (22). The resultant mixture (24) is mixed with exhaust gas (25) from the first stage. This mixture (12) is then burned. In the second stage, combustion air may be used and with the excess air being, at least, as large as that of the first stage.

    Abstract: The burner has a body (26) of two hollow, conical bodies (1,2) which are disposed offset to one another, so that their centre axes (4,5) is in the flow direction. A tapered cavity is formed, expanding towards the flow direction, having tangential air-intake grooves (7) between the conical bodies. A number of fuel supply openings, for gaseous fuel, are evenly distributed in the overall area of the grooves. At the upstream end of the cone burner, a central liquid fuel nozzle (15) is arranged, leading into the burner cavity; whereas at the downstream end, the conical bodies posses a common outlet diffusor (27). Towards the discharge diffusor the two conical bodies have a transient area (28), which continuously takes the weight of the air-intake grooves in the flow direction. The diffusor is circular and is formed without any grooves.
