Difference between single-channel burner and multi-channel burner
2025-08-28
(1) Combustion Efficiency
Single-channel burner: lower fuel and air mixing and combustion efficiency.
Multi-channel burner: increases mixing of fuel with multiple air streams, improving combustion rate and efficiency.
(2) Primary Air Usage
Single-channel burner: large primary air volume, accounting for 20% to 40%.
Multi-channel burner: reduces primary air usage, improves utilization of high-temperature secondary air, increasing system thermal efficiency.
(3) Structural Aspect
Single-channel burner: simple and singular structure.
Multi-channel burner: complex structure, more in line with combustion principles.
(4) Flame Control
Single-channel burner: flame shape is difficult to control, flame length is relatively short.
Multi-channel burner: flexible adjustment of air volume and velocity, longer flame length, high-temperature flame zone can reach about 6-13 meters, achieving precise control of flame shape and temperature field.
(5) Adaptability
Single-channel burner: high requirements for fuel type and quality, suitable for projects with low calcination process demands.
Multi-channel burner: beneficial for utilization of low volatile, low reactivity fuels, lower fuel operating costs, energy-saving effect superior to single-channel structure.
(6) Environmental Protection
Single-channel burner: higher emissions of harmful gases such as NOx.
Multi-channel burner: reduces NOx generation, achieving clean and environmentally friendly operation.
(7) Application Aspect
Single-channel burner: suitable for early-stage and low calcination process requirement fields; equipment has low initial investment, safe, economical, and practical.
Multi-channel burner: widely used in cement kilns, lime kilns, ceramsite kilns, pellet kilns, and other medium to high-temperature calcination processes; high combustion efficiency and significant energy-saving effects.
