What Preparations Need to Be Made for on-site Commissioning of Low Nitrogen Burner?
Low nitrogen burner is a general term for devices that mix fuel and air spray in a certain way. Most of them are made of corrosion-resistant and high-temperature materials such as stainless steel or titanium metal. The low nitrogen burner is used to atomize the sample through flame combustion. The atomized test solution enters the low nitrogen burner. Under the action of flame temperature and flame atmosphere, through drying, melting, evaporation, dissociation, and other processes, a large number of ground-state atoms and some excited atoms, ions, and molecules are produced.
Site test preparation:
1. According to the regulations, the flue near the furnace shall be provided with a measuring hole (aperture 50mm – 60mm) to facilitate flue gas detection and air volume detection; There shall also be a flue gas analysis measuring hole (aperture 10mm).
2. At least one commissioning professional shall be equipped. In the process of checking the ultra-low nitrogen burner, it is necessary to check the safety of electric control (the ultra-low nitrogen burner needs to be restarted at least 3 times); It is also necessary to adjust the output power of the burner and test the large and small loads to the design value of the burner. The specific steps are as follows:
Heavy load: adjust the flow to the design value. After the flow is stable and the flame is stable, measure the flue gas, record the stable data of the flue gas value (oxygen content, nitrogen oxide) of the ultra-low nitrogen burner, measure the noise, surface temperature, and if the flue gas value does not meet the requirements, such as the furnace back pressure, it is necessary to continuously adjust the status of the ultra-low nitrogen burner until the flue gas reaches the standard.
Small load: adjust the flow to the design value. After the flow is stable and the flame is stable, measure the flue gas, record the data after the flue gas value (oxygen content, nitrogen oxide) is stable, and measure the furnace back pressure during the measurement. If the flue gas value does not meet the requirements, it is necessary to continuously adjust the state of the ultra-low nitrogen burner until the flue gas reaches the standard.
