HLPB duct burner

HLPB duct burner elements are designed for heating process air in motion, The burner elements are mounted inside the process air duct directly in the air stream being heated. The air stream passes across the burner and through the mixing plates and is used as combustion air, thanks to the proper profile plate setting. HLPB duct burner suitable for natural gas, propane, COG, and some other low heating value gas mixture. HPLB burner elements can work in high upstream temperature up to 540˚C, and low oxygen circumstances, max process air up to 850˚C

HLPB burner elements are modules designed can be easily cascaded to various layouts according to your specific heating requirement, Please consult us with your project-based demands.

Typical Burner Data

 

Burner Type HLPB_ LT HLPB_ HT HLPB_ SF
Max capacity per unit(kW) 700 700 1500
NG gas pressure(mbar) 70 70 1000
Flame length(m) 2 2 2.5-4.5
Pressure drop(mbar) 0.5-0.6 0.4-1.5
NOTE
1. Burner data is tested with natural gas at 15°C, with 10 kWh/Nm³, sg=0. 59
2. Max and min capacities are highly dependent on applications
3. Natural gas pressure at the burner inlet is tested with the maximum fire capacity, which can be different with different gas quality
4. Flame length is measured in highest capacity, and will be heavily affected by process air temp, O₂, and velocity
