Many places are carrying low-nitrogen burners transformation, especially the particularly low nitrogen Burner transformation. We use low - NOx burner modifications for what? What is the role of low nitrogen burners is that? With the view of the low NOx combustion is used for? Natural gas burner process and operating specifications
Natural gas burner process and operating specifications
Gas burner combustion processes and practices: purge. So that the damper is opened (the fixed damper itself is open, active damper will automatically open stage, multi-stage active damper will open to the damper or other opening) operation of the fan blowing fresh air only into the combustion chamber to the combustion chamber may replacing all flammable gas blow fresh air to avoid detonation, explosion / blow back when the incident electric ignition. Typically 15-30 seconds. Large machine longer. "Combustion chamber" or some temperature control is not a firm requirement concerning open a small place, this step is no or very short, burner also generally little power, but also by the high power requirements of multiple low-power burner composed of all for explosion-proof or perhaps decreased. Pre-combustion. Generally 2 seconds. The throttle opening to a small fire burning position, just spark burning, does not open the gas valve, this step is generally set to a large machine is still detected at this time as well as the function is normal combustion, i.e., abnormal alarm confessed; if the valve is generally will always leak purging unclean, then perhaps there will be an electric burner flame, burner flame detection system will find undeserved flame burner will confess alarm (this is not all programmable devices have this function) even without this function, to the point it was lit you can reduce the risk of gas accumulation. Typically 3-5 seconds, the combustion time, is an essential function of all programmable. During this time, in a small fire damper position, open the gas valve (valve open method is not different, as is the classic point to be open with a small degree of opening to the set value and then gradually opened, the closure is is immediately fully closed burner electric arc consistent release, during which the gas must be lit, lit only tune into the normal combustion and power adjustment stage, lit up, the burner will release a series of job no longer arc. kindle will immediately confessed to the police. demand from scratch and then manually re-initiate debugging. domestic kitchen with a small machine no programmer, in order to avoid loss of combustion, burner is consistently adhered to the job, but also to allow the gas can be lit on the burner is lit to avoid agglomeration the bottom of the tank with the drain valve is assumed that, from time to time should be turned open valve discharge water accumulated in the bottom of the tank and dirt, if perhaps, the inner wall of the tank should be cleaned. a longer time intervals, clean burning inside the machine.
