Drying Characteristics of 25 kW Class Industrial Dryer Adopting Mat Type Premixed Catalytic Burner

매트 형태의 예혼합 촉매 버너를 활용한 25 kW급 건조기의 성능 특성

A catalytic burner has been developed to utilize thermal energy from the fossil fuel without nitrogen oxides (NOx) emission. The burner is shaped into a mat to maximize the heating surface. Premixed combustion has been developed to be used in a closed chamber, such as a radiation type industrial dryer. The burner yields the thermal energy in the form of thermal radiation in the infrared regime, which is proved to be effective to dry organic substances for low moisture condition. Thermal efficiency including the sensible heat is better correlated to the moisture compared to the dry rate.
