Product Advantages
Key benefits of 5L-150 Paddy Husk Hot Air Furnace
Energy Efficiency with Renewable Sources
Our hot air furnaces use renewable energy sources like rice husk, making them environmentally friendly and sustainable. 1KG rice husk generates 3200Kcal, providing efficient heat generation.
Environmental Protection
Our furnaces have low smoke emissions and minimal exhaust gas, complying with national environmental standards. Suspension combustion technology ensures complete combustion with minimal pollution.
High Safety Operation
Our hot air furnaces can be operated without annual inspections or the need for a certified license, unlike boilers which require licensed operators. Negative pressure operation ensures safety.
Economic Efficiency
1KG biomass generates 4000Kcal, 1KG grain shell generates 3200Kcal, 1KG diesel generates 8670Kcal. Price of biomass is around 0.1 USD/KG, grain shell is around 0.05 USD/KG while 1 USD/KG for diesel.
Cost Comparison Analysis
1Kg biomass with 0.1 USD can supply the same power generated by 0.46KG diesel with cost of USD 0.5; 1KG biomass with 0.05 USD can supply the same power generated by 0.37KG diesel with cost of 0.4 USD.
Waste Utilization
Effectively utilizes agricultural waste (rice husk) that would otherwise be discarded, turning waste into valuable energy resource for grain drying operations.
Product Features
Specialized features for efficient and reliable hot air generation
High Thermal Energy Output
The thermal energy generated is sufficient to supply 6 units of 32T dryers under normal conditions. 1.5 million Kcal/hour heat output meets demanding commercial drying requirements.
Fully Automated Operation
Automatic feeding, temperature control, combustion and ash cleaning. Reduces operator physical effort and ensures overall drying precision with consistent heat supply.
Automatic Feeding System
The feeding rate can be controlled based on the dryer's temperature requirements. Frequency conversion control allows precise adjustment of fuel input for optimal efficiency.
Precise Temperature Control
