A hot air stove is an efficient, environmentally friendly, and energy-saving thermal energy device mainly used to heat air to the desired temperature and then deliver it to various places that require hot air to meet different process requirements. A hot blast stove generates heat by burning fuel, and then transfers the heat to the air, causing the air temperature to rise. This process is similar to using a hair dryer at home, which circulates hot air in the furnace cavity through the rotation of the fan, thereby heating the product. ‌

There are various types of hot air stoves, including direct high purification gas hot air stoves and indirect gas hot air stoves. The direct type hot blast stove uses fuel for direct combustion, forming high-temperature combustion gas, which is further mixed with external air and enters the drying or baking room. It is suitable for occasions that require high-temperature drying. Indirect hot air stoves are suitable for drying thermosensitive materials that are not allowed to be contaminated or have low temperatures, and heat exchange is carried out through carriers such as steam and thermal oil.

Hot blast stoves are widely used in many industries, including the main auxiliary equipment of airflow drying, spray drying, fluidization transformation, tower drying, tunnel drying and rotary drying. In addition, it is also used for heating greenhouses and livestock farms, and is widely used in agricultural production, agricultural products and food processing, metallurgy, building materials and other industries.
