Meker-Fisher burner

A Meker-Fisher burner or Meker burner is a laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion. It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations. The burner was introduced by French chemist Georges Méker in an article published in 1905.〔G. Meker. Nouveaux bruleurs de laboratoire et leur application au chauffage a temperature elevee. J. Phys. Theor. Appl., 1905, 4 (1), pp.348-354.〕
The Meker-Fisher burner heat output can be in excess of per hour (about 3.5 kW) using LP gas.〔(Durham Geo )〕 Flame temperatures of up to are achievable. Compared with a Bunsen burner, the lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and gas. The tube is wider and its top is covered with a wire mesh which separates the flame into an array of smaller flames with a common external envelope, ensures uniform heating, and also prevents flashback to the bottom of the tube, which is a risk at high air-to-fuel ratios, and limits the maximum rate of air intake in a Bunsen burner. The flame burns without noise, unlike the Bunsen or Teclu burners.〔
