Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
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.
Hence optimal flow control is required. Bronkhorst 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 mass flow controllers must operate with very low backpressures. Burner manufacturers want customised pre-tested solutions, instruments with digital (bus) communication and easy to start-up. Flame arrestors may be required and can be supplied.
Burner Ratio Control
For every burner application two flow gases are required: the fuel (methane, propane or acethylene) and the oxidant (air or oxygen).
In order to attain an ideal combustion flame and maintain its dynamic behaviour constant, it is crucial to control accurately the ratio between both gases. The necessary stechiometry of air must be guaranteed, otherwise security may be compromised.
At the same time, and to avoid excessive fuel spendings 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 respecting the necessary stability. As the combustion gas is supplied by a flow controller (Master), the oxidant gas is delivered accordingly in the correct proportion by another flow controller (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.
