The picture is taken as part of a wider experimental study on Combustion of Bio-fuels. The initial set of experiments includes method to stabilise a Methane flame. The premixed of Methane and Air flows through a circular nozzle. A glass plate is mounted flat at 30 mm downstream of the nozzle. The flame is stabilised between the nozzle and the glass. During combustion process the temperatures at the flame reach 2500°C. The flame is visible in circular blue shade. The radiance from the combustion products is visible in pink shade. The picture is taken with a Nikon D80 camera, with an 18-200 VR lens. The aperture and the shutter speed are varied depending on the requirements. The wire is visible in yellow shade. The bright yellow shade around the wire is due to long exposure. The picture is in its original form.
