Abstract
Counterflow burner having a combustion chamber (5) to which combustible gas (B) and an oxidising agent (0) can be fed from opposite sides, having three planar substrates (1, 2, 3) which are interconnected, lying one above the other, the middle substrate (2) having the combustion chamber (5), from which passages (4), lying in the plane of the substrate, lead to the edge, the upper substrate (3) and the lower substrate (1) being closed, and at least the middle substrate (2) is produced using methods of microsystem technology.
Claims8
Counterflow burner comprising:
- a combustion chamber (5) and passages (4) for conveying a combustible gas (B) and an oxidizing agent gas (0) to the combustion chamber from different directions, having three planar substrates (1, 2, 3) which are interconnected, lying one above the other, the middle substrate (2) having the combustion chamber (5), from which the passages (4), lying in the plane of the middle substrate, lead in opposite directions to the edge of the substrate in a radial manner, and the combustible gas (B) and the oxidizing agent (0) introduced through the passages from opposite directions collide in the combustion chamber so two oxidizing agent gas streams and two combustible gas streams meet from exactly opposite directions and achieve a flame front having a spherical shape, and at least the middle substrate (2) being configured as a microsystem;
- wherein the upper substrate (3) and the lower substrate (1) are closed except for openings which are directed towards the combustion chamber and through which gas can enter or discharge perpendicularly to the plane of the substrates.
