摘要： A fuel selected from powder fuels and liquid fuel is ejected through a fuel ejection pipe having an annular ejection opening; primary air is ejected through primary air-ejecting openings arranged on outer and inner sides of the fuel ejection, to form outer and inner primary air-ejection straight streams between which the fuel ejection stream is interposed, and to burn the fuel ejection stream. When a powder fuel is used, optionally, a liquid fuel is further ejected and mixed with the above-mentioned primary air streams, and the liquid and powder fuels are burnt together.
