Direct Oil/Gas Fired Hot Air Furnace

Product Introduction
Direct Oil/Gas Fired Hot Air Furnace is mainly composed of the burner, furnace body and control system. The burner adopts imported integrated burner. Fuel and air enter the furnace body at a certain ratio and burn completely inside. Ambient air passes through the furnace jacket and mixes with high-temperature flue gas to obtain clean flue gas at required process temperature. Single unit heat supply capacity: 50-200x10^₄ Kcal/h. Heat supply temperature ≤1000°C.

The indirect fired hot air furnace is based on direct fired furnace with added plate heat exchanger. High-temperature flue gas exchanges heat with high purity air to obtain high-cleanliness hot air. After heat exchange, flue gas is discharged by induced draft fan while ambient air is sent into heat exchanger by forced draft fan. Heat supply temperature range: 50~450°C.

Technical Characteristics:

• Compact size, less than 1/2 volume of traditional hot air furnace
• Light weight, only 1/3-1/4 of traditional furnace weight. Lower steel consumption and cost
• Complete combustion with clean operation environment; meets environmental standards without secondary pollution
• High cleanliness hot air; convenient temperature adjustment
• Simple operation and easy adjustment
• Equipped with manual/automatic control functions
• Special anti-expansion design for indirect-fired furnace effectively solves thermal expansion issues
• With functions of automatic ignition, load adjustment, flame detection and alarm 

Application Scope:

Daily chemicals, ceramics, fertilizers, chemicals, food, pharmaceuticals, feed, environmental protection, building materials, etc.
