Abstract
In order to develop a mechanism of clean and efficient combustion, this study studied the combustion mechanism of stover semi-gasification by a clean stove designed. The experimental material was corn Stover briquettes. Process of semi-gasification combustion can be divided into two parts: gasification stage and combustion stage. First, under the low primary air amount, stover gives off partly combustible gas (Volatile matter). Then, the combustible gas rises and burns in the upper Furnace when it meets higher secondary air amount. At the same time, the residue remained in bottom Furnace keeps on gasifying and burning under high temperature until the fuel is exhausted. In the process, two phases (solid and gas) combustion becomes into one phase (gas) combustion. Due to inadequate primary air and low temperature of semi-gasification chamber (550-750℃), all the ash was loose and no slag was found. Moreover, combustible gas produced was directly completely burned off and no tar appeared in the emissions. According to the result, the combustion thermal efficiency of clean stove (75%) is up to 75% and higher than primary stove (below 12%).
