Low-NOx Riello burners integrate traditional combustion equipment by adding fans, induced draft fans, variable frequency drives, control valves, and multi-loop systems to achieve clean energy and efficient combustion, providing more efficient heat to the boiler. The following outlines the preparatory work and precautions for on-site inspection of low-NOx combustion equipment.
**Site Safety:** Before commencing the on-site inspection, the low-NOx Riello burner manufacturer or user should inform the inspection personnel of on-site safety instructions, conduct safety training and education as necessary, and ensure proper safety precautions are taken.
**Site Safety:** The low-NOx Riello burner manufacturer or user should inform the inspection personnel of on-site safety instructions, provide necessary safety training and education, and ensure proper safety protection measures are in place. In addition to the application materials submitted before the exam, the following materials are also required depending on the actual on-site conditions:
1. Inspection of gas or oil combustion equipment: The main pipeline must be equipped with an oil flow meter, and a flow meter inspection certificate must be provided;
Biomass pellet combustion equipment testing: Weighing equipment (such as electronic scales, balances, etc.) is required on-site to weigh the actual weight of the feed; Testing of combustion equipment for other gaseous or liquid fuels: The main pipeline must have a fuel flow meter for fuel consumption testing;
2. Provide an on-site fuel testing report for the low-NOx combustion equipment (including fuel composition analysis, calorific value, and other testing items).
Regarding on-site preparation for domestic burners:
1. As required, the chimney near the stove should have a suitable measuring hole (50mm~60mm) for flue gas detection and airflow detection, and a measuring hole (10mm) for flue gas analysis.
2. At least one professional commissioning technician must be present. When inspecting the low-NOx combustion equipment, the safety of the electrical control must be checked (the low-NOx combustion equipment must be restarted at least 3 times), and the output power of the combustion equipment must be adjusted and the small load of the large combustion equipment design value must be tested. The specific steps are as follows: High load: Adjust the flow rate to the design value. After the flow rate and flame stabilize, measure and record the flue gas data. Once the flue gas value of the low-NOx (oxygen, nitrogen oxides) combustion equipment stabilizes, measure the noise, surface temperature, and flue gas value. If necessary, continuously adjust the state of the low-NOx combustion equipment if requirements are not met, such as furnace back pressure, until the flue gas meets the standards. Low load: Set the flow rate to the design value. After the flow rate and flame stabilize, measure the flue gas, recording the flue gas value (oxygen content, nitrogen oxides) and the data after the furnace back pressure stabilizes. If the flue gas value does not meet the requirements, the operating conditions of the low-NOx combustion equipment must be continuously adjusted until the flue gas meets the standards.
