Introduction of Biomass Hot Air Furnace
The biomass hot air furnace is a new-generation, high-efficiency heat transfer system that uses environmentally friendly biomass fuels, such as biomass pellets, biomass residues, and wood chips, as fuel and air as the heat transfer medium. It is widely used in grain processing, feed production, food processing, chemical processing, bio-energy, and other industrial applications.
Advantages of Biomass Hot Air Furnace
01
Complete Combustion & Clean Hot Air
Efficient combustion with virtually no visible smoke, providing a clean operating environment and meeting applicable environmental protection requirements without secondary pollution.
02
High Hot-Air Cleanliness
Low particulate concentration in the hot air, typically 30–120 mg/Nm³.
03
High Thermal Efficiency
Thermal efficiency of over 95%, reducing fuel consumption and operating costs.
04
Precise Temperature Control
Hot-air temperature can be conveniently adjusted to below 900°C, with continuous hot-air supply and temperature stability within ±5°C.
05
Easy Operation & Control
Simple operation with convenient and precise adjustment of combustion and hot-air output.
06
Safe & Reliable Operation
Designed for safe and stable operation, minimizing operational risks such as over pressure and explosion hazards.
Working Principle of Biomass Hot Air Furnace
It uses biomass pellets, wood, straw, sawdust, bagasse and other biomass materials as fuel, which burns in the combustion chamber to generate high-temperature flue gas. Through indirect heat exchange via finned tubes or tube banks, the flue gas transfers heat to clean air, delivering clean hot air to the dryer. The flue gas and air are fully separated and never in contact, preventing the material from being contaminated by smoke or dust.
