Product number: C552

An instrumentation console provides an adjustable and measured flow of both air and gas. Two flowmeter in series, ensure that a wide range of typical slow burning gaseous fuels (e.g. Propane, Butane, Methane LPG) can be used and measured accurately. For operator safety an interlock ensures that gas flow can only be initiated with an operator actively in attendance.

Both air and gas are separately introduced into a mixing block designed to accommodate a variety of burner mixing tubes and adapters.
Various settings of air fuel ratios allow the stability characteristics of a gas flame to be examined, and the upper and lower stability limits of both “lift off” and “light back” plotted on a stability diagram.

The dual structure of pre-aerated flames is illustrated with the aid of the "Smithells” separation experiment. A length of heat resistant glass tube and supporting ring is provided to enable the primary and secondary flames to be separated.
