The fuel-gas mixed air hot air furnace is a highly efficient and energy-saving new type of heating equipment. It uses diesel and natural gas as fuel and adopts a smoke-air mixed design, capable of generating clean hot air with a maximum temperature of 500℃. The equipment has a horizontal quick-installation structure, with the combustion chamber and heat exchanger integrated. Through forced circulation by the fan, the combustion heat is efficiently transferred to the air, and the hot air and exhaust gas do not mix, ensuring cleanliness and no pollution. It is widely used in scenarios such as grain drying, food processing, medicinal material drying, coating curing, textile printing and dyeing, and chemical raw material drying

Environment Optimized Blending Air Horizontal Dual Fuel Hot Air Boiler, Zero Extra Smoke Industrial Heating Furnace
The mixed air design features high air volume, stable air pressure, a wide range of outlet air temperature, and can be customized for air volume and temperature according to the drying process. Before leaving the factory, the air tightness and combustion debugging are carried out, and it can be put into production by simply connecting the air duct on site. It is widely used in scenarios such as food and medicinal material drying, grain drying, spray painting curing, greenhouse breeding heating, and chemical raw material dehydration.

Description
The horizontal oil/gas clean air hot air furnace adopts a fully enclosed horizontal furnace chamber structure and an independent clean air distribution system. Fresh and clean air is sent into the combustion chamber in proportion, allowing for precise control of the air-fuel ratio and avoiding the problem of impurities carried back by the return air in the mixed air furnace models. The entire machine adopts a fully wet back furnace body design, with sufficient heating area inside the furnace chamber, supporting dual fuel combustion of fuel oil, natural gas and liquefied petroleum gas. No dust is produced during the combustion process, and the structure design ensures pure hot air.
