The fuel is burnt through the burner and generates hot fumes, and the hot fumes will exchange heat with the cold air. After the heat exchange, the temperature of the air is increased to required level and then blown into the inner part of dryer. When the
temperature of the hot air has went up to its rated maximum value, the burner will automatically stop burning or turn to burn in small flame; When the temperature has went down to its rated minimum value, the burner will be reignited or turn to burn in big flame. The speed of temperature increase can be adjusted by the air inlet valve.
