Experiments have been performed to extract the fundamental combustion characteristics of solid waste fuels in flowing combustion gas produced from flat flame burner. The burning behavior are observed by taking the direct photographs with video camera. It is concluded that there are three combustion processes of solid waste fuels burning in high temperature environment such as gas phase ignition, luminous diffusion flame and surface combustion and flame behavior can be classified three types depending on gas flow velocity, temperature and oxygen concentration, that is, envelope flame, wake and lifted flame. The boundary gas flow velocity between stable and unstable combustion is determined by the variation of flame configuration from envelope to wake or lifted flame.
