  • 본 연구는 섬유 코팅 건조기에서 사용하고 있는 열풍 건조방식을 촉매버너를 이용한 직접 건조 방식으로 대체하기 위한 것이다. 촉매버너는 파이버 매트를 사용한 확산식 연소 방식을 채택하였다. 확산식 촉매버너는 코팅 건조기와 같은 밀폐형 구조에는 적합하지 않아서 개선이 필요한 것으로 나타났다. 연소용 공기를 촉매버너의 표면에 강제적으로 공급하여 촉매버너의 연소효율을 개선하였다. 아크릴이 코팅된 섬유의 건조 과정에서 발생하는 톨루엔을 회수하여 촉매버너의 연료로 재사용하도록 하였다. 이를 위하여 톨루엔을 사용한 경우의 촉매버너의 최적 설계조건을 도출하였다.

  • Flameless fiber mat catalytic burners have been known as an effective heat source in industrial drying processes since heat obtained from combustion can be transferred to absorptive body by far-infrared radiation. In order to extend the application of fiber mat catalytic burner, novel fiber mat catalytic burners were manufactured and combustion characteristics of them were investigated. For diffusive catalytic burners, the efficiency of combustion was significantly affected by the installation direction and the temperature of catalytic bed perimeter influenced on the diffusion rate of oxygen which determined the combustion efficiency of catalytic burner. It was seen in premixed catalytic combustion that air content in premixed fuel gas was optimized at slightly higher than theoretical amount of air. Combustion heat released higher than 70% by radiant heat in premixed catalytic combustion likewise diffusive catalytic combustion.

  • The fiber mat catalytic burner that uses infrared radiative heat obtained by flameless catalytic combustion was manufactured and tested to investigate its combustion characteristics. About 9 to 17% of combustion heat was released by sensible heat during the premixed catalytic combustion depend on combustion condition. To find out radiation intensity with distance between catalytic burner and sample, the equation that calculate the receiving surface of radiative energy under the fiber mat catalytic burner was driven. This equation was well correlated with the drying rate of melamine. The drying experiments were carried out to the melamine, wood chip and agricultural pallet by using the fiber mat catalytic burner and the energy efficiency was calculated from drying rate of them. The energy efficiency of the fiber mat catalytic burner reaches to 79% in maximum for drying of the wood chip.

  • A catalytic burner that utilizes the thermal energy from fossil fuels without the emission of nitrogen oxides ($NO_x$) has been developed. For this purpose, the newly developed burner has two features: firstly, it is in the shape of a flat mat so as to maximize its heating surface, and secondly, it adopts premixed combustion so that it can be used in a closed space. In the present study, the burner was used in a radiation-type industrial dryer. This dryer yields thermal energy in the form of thermal radiation in the infrared regime, which has been proved to be effective for drying organic substances under low-moisture conditions. Analysis of the experimental data has proved that the thermal efficiency of the dryer is better correlated to the moisture than to the dry rate
