Important Notes for Type Selection
1.Control Mode of Burners
Comflame burners are designed with a wide range of combustible gas regulation ratio. Stable combustion can be ensured in case of excessive combustion air or excessive combustion gases. Several control methods can be used to regulate the combustible gases, e.g. diaphragm regulation, mechanical regulation and electronic regulation.
2. Ignition and Flame Detection
Comflame burners are designed with three independent holes, which are used to install the ignition nozzle, flame detector and observation window. Optional flame detectors include the ultraviolet flame detector or flame ion detection rod. The installation positions of the ignition nozzle, flame detector and observation window can be adjusted based on actual operation conditions to ensure higher stability and accuracy of ignition and flame detection. Manual ignition using a torch is allowed in special cases. However, excessive flow of combustion air should be avoided in this case. Otherwise, ignition may fail.
3. Type Selection at Pre-heated Air Environment
The Superflame burner can use the environment air and high-temperature preheated air (in case the burner nozzle is made of alloy) (up to 370ºC). In the case of pre-heated air environment, see the rated power values under "pre-heated air combustion" (370ºC) in the typical parameter sheet to select proper types.
