Burners are usually found in welding, cutting or furnace applications. All these applications require an extremely efficient flame control. Gas flow has got a preponderant role on achieving good characteristics of combustion flame. Therefore optimal flow control is required. deliver proportional gas flow while assuring the necessary stability. As the combustion gas is supplied by a MFC (Master), the oxidant gas is delivered accordingly in the correct proportion by another MFC (Slave), in such way successful ratio control is accomplished. The instruments do have a fast response time which, together with a unique stability guarantees flame's constancy. 

Bronkhorst High-Tech is fully aware of the demands involved and has developed throughout the years unique solutions for burner applications.

For these processes the pressure of the gas is critical. Pressure irregularities may cause the flame to be extinguished or increase the resultant amount of NOx. Usually the MFCs must operate with very low backpressures. Burner manufacturers want customized pre-tested solutions, instruments with digital (bus) communication and easy to start-up. Flame arrestors may be required and can be supplied.

For every burner application two flow gases are required: the fuel (methane, propane or acetylene) and the oxidant (air or oxygen). In order to attain an ideal combustion flame and maintain its dynamic behavior constant, it is crucial to control accurately the ratio between both gases. The necessary stoichiometry of air must be guaranteed, otherwise security may be compromised. At the same time, and to avoid excessive fuel usage and to downplay NOx emissions, it should be possible to use the minimum required air amount.

 The solution presented can successfully deliver proportional gas flow while assuring the necessary stability. As the combustion gas is supplied by a MFC (Master), the oxidant gas is delivered accordingly in the correct proportion by another MFC (Slave), in such way successful ratio control is accomplished. The instruments do have a fast response time which, together with a unique stability guarantees flame's constancy.

When sizing and calibrating a thermal mass flow meter or controller, one needs to use a specified fluid as the reference.  As the fluid in an application will very often be different from the reference fluid, a conversion factor between the two fluids must be used.  Bronkhorst uses Air as our reference gas and Water as our reference liquid.

Bronkhorst developed a unique database, consisting of fluid data of over 600 fluids. Using application software routines various calculations can be made on-line at our internet site www.fluidat.com

 

 

We invite our customers to visit this site for a free registration. Upon receipt of their login details they will be able to calculate conversion factors/tables for Bronkhorst thermal gas & liquid flow meters, calculate Kv-values and orifice sizes for Bronkhorst control valves, calculate the pressure drop across in-line filters and perform calculations relevant to our CEM evaporation system.
