Selecting a burner for a 2-ton boiler (approximately 1.4 MW or 1.2 million kcal) requires consideration of several factors: fuel type (natural gas, diesel, light oil, biomass), boiler type (e.g., horizontal WNS, vertical), low-NOx emission requirements, and furnace back pressure. The key objectives are to match the power output (1.2–1.4 million kcal/h), ensure high thermal efficiency (typically >90% for gas burners), and comply with environmental emission standards. For boilers with a capacity of 2 tons or more, a horizontal burner configuration is generally recommended.
I. Key Selection Factors
Fuel Type: Select natural gas, LPG, diesel, or methanol based on locally available resources.
Burner Capacity: A 2-ton boiler (1.4 MW) typically requires a burner with an output of approximately 1.2 million to 1.4 million kcal/h.
Low-NOx Environmental Requirements: If NOx emissions must be kept below 30 mg/m³, a premix burner or a dedicated low-NOx burner must be selected.
Furnace Back Pressure: The burner must be matched to the boiler's furnace pressure to prevent flashback or incomplete combustion.
Control Method: Proportional control is recommended, as it allows for better adaptation to load fluctuations and helps conserve fuel.
II. Configuration Guidelines for 2-Ton Boiler Burners
Gas Boilers (Natural Gas/LPG): It is recommended to install a fully automatic gas burner to ensure high combustion efficiency; pay close attention to selecting an appropriate gas valve train to ensure safety.
Oil Boilers (Light Oil/Diesel): The burner must be matched with a suitable oil pump and nozzle; pay attention to the viscosity of the fuel oil and ensure proper filtration.
Low-NOx Retrofitting: In regions with strict environmental regulations, low-NOx premix combustion technology must be adopted.
III. Selection Steps
Clarify Boiler Parameters: Determine whether the boiler produces hot water or steam, and verify its rated output and designed thermal efficiency.
Calculate Actual Requirements: The required fuel consumption for a 2-ton boiler is calculated as: Boiler Output / (Fuel's Lower Heating Value × Boiler Efficiency).
Compare Brands and Services: Evaluate the reliability of the burner manufacturer and the availability of after-sales spare parts.
On-site Back Pressure Testing: Have a professional measure the resistance within the furnace to select a burner with the appropriate air pressure capacity. Typically, for a two-ton boiler, it is recommended to prioritize mainstream industrial brands for the burner to ensure long-term stable operation and compliance with environmental standards.
