Patented Technology and High Performance
1. Multiple Furnace Types for Different Processes
Meibao can provide direct fired hot air furnace and indirect fired hot air furnace according to different production requirements.
The direct fired hot air furnace has high thermal efficiency and fast temperature rise. It is suitable for drying systems where clean combustion hot air can directly enter the process.
The indirect fired hot air furnace uses a heat exchanger to separate flue gas and clean air. It is suitable for materials or industries with higher air cleanliness requirements.
2. Flexible Fuel Options
The furnace can use gas, oil, coal, biomass and other fuels. Customers can choose natural gas, diesel, heavy oil, coal, biomass pellets, wood chips, rice husks and other local fuels according to fuel price and supply conditions.
This flexible fuel design helps reduce operating cost and supports stable production in different markets.
3. Stable Hot Air Temperature
The hot air furnace can provide stable hot air for drying systems. The outlet air temperature can be adjusted according to process demand, helping the production line keep steady operation and product quality.
The system can also be equipped with automatic temperature control, flame detection, air volume control and safety protection devices.
4. High Efficiency and Energy Saving
The furnace adopts efficient combustion and heat exchange design. For indirect type systems, countercurrent heat exchange can improve heat transfer efficiency. Dust removal and flue gas purification can also be configured to protect the heat exchanger and extend equipment service life.
This high efficiency hot air furnace helps customers reduce heat loss, save energy and lower long-term operating cost.

For drying projects, the hot air furnace can be connected with the downstream dryer to form a complete industrial air heating system. It can provide stable heat source for continuous production.
Application Scenario
Chemical Industry Drying
The industrial hot air furnace can be used for drying chemical powder, granules and raw materials. It can be matched with rotary dryers, drying rooms and other drying equipment.
Detergent Powder Production
The hot air generator can provide hot air for spray drying towers in detergent powder production lines. It helps keep stable drying temperature and supports continuous operation.
Fertilizer and Feed Industry
The furnace can provide hot air for drying fertilizer granules, feed materials and agricultural materials. Coal fired hot air furnace and biomass fired air heater are often selected when customers need lower fuel cost.
Ceramic and Building Materials Industry
The hot air furnace can be used for drying ceramic materials, sand, sludge, mineral powder, cement-related materials and other building materials.
Food and Medicine Industry
For processes with higher cleanliness requirements, the indirect fired hot air furnace can be selected. It separates flue gas and clean air through heat exchange.
Environmental Protection Projects
The hot air furnace can be used in sludge drying, waste treatment drying and other environmental protection systems.
Material Introduction
The hot air furnace is designed according to working temperature, fuel type, air volume, flue gas condition and application industry.
The furnace body can use suitable steel structure and insulation materials to reduce heat loss and improve service life. The combustion chamber can be designed with heat-resistant materials according to the fuel and combustion temperature.
For indirect fired hot air furnaces, the heat exchanger is an important part. The heat exchange pipe material can be selected according to temperature, dust content and corrosion condition. Countercurrent heat exchange, jet flow structure and internal plug-in structure can be used to improve heat transfer performance.
For coal fired and biomass hot air furnaces, dust removal and flue gas purification devices can be added to reduce dust entering the heat exchanger. This helps protect the system and keep stable thermal efficiency.
The final material configuration can be customized according to the customer's process, budget and local operating conditions.
