摘要：
The combustion of porous media is characterized by high efficiency and good stability. A simple cubic packed structure consisting of an alumina particle packed bed and double-layer silicon carbide foam ceramics was proposed to study the filtration combustion characteristics of the structure. By changing the premixed gas equivalent ratio and inlet velocity, the flammability limit of flame, flame propagation law, CO emission law, and combustion efficiency under different working conditions were studied. It is found that the stabilization and propagation of the flame depend on the regional temperature, the equivalent ratio, and the velocity. In the bed with a particle diameter of 40 mm, the flame is easy to spread and the combustion efficiency is high, while in the bed with a particle diameter of 20 mm, the flame is more stable. © 2023 Shanghai Jiao Tong University.
