전산유체역학을 이용한 공기온도변화에 따른 목재펠릿의 연소특성 분

초록

The global increase in energy consumption has caused serious environmental pollution issues, which have highlighted the need for new and renewable energy sources. Solid fuel pellets produced from the crushing, drying, and pelletizing of lignocellulosic biomass can be a possible replacement for fossil fuel coal because it is carbon neutral fuel. On the other hand, the characteristics of pellet combustion depends largely on the environment, such as the inlet air temperature and humidity. This study examined the combustion characteristics of wood pellets in terms of the inlet air temperature and compared the experimental results with the simulations obtained by computational fluid dynamics (CFD). As a result, the improved combustion model, including the inlet air temperature variation, showed better agreement with the experimental data by obtaining lower root mean square error values than from previous models in terms of the inlet air temperature.
