• Counterflow burner

The axisymmetric co-flow burner consists of two concentric tubes made of stainless steel. Metered quantities of fuel and air are supplied from radial inlets to a mixing chamber. The mixture, from the chamber is passed through a central core tube having 10 mm internal diameter. Surrounding this core tube, there is a co-flow tube of 42 mm internal diameter. Secondary air is supplied through this co-flow tube. Fine meshes are placed in the tube to filter eddies. This also helps in intercepting the flame, in case the flame flash backs into the tube.
