摘要： PURPOSE:To perform a low air ratio combustion and a complete combustion at the time of a low heating value by disposing a central body at the center of a cylinder in a secondary combustion area. CONSTITUTION:A secondary air blown out of the inner wall of a burner is rectified along the inclined surface of a central body 7 of a secondary combustion area 8 above a burner pot 1 and elevated. Since the flow stream line of a fluid can be made constant because of the presence of the central body 7, the flow of fluid the same as that at the time of the maximum heating value can be obtained even at the time of a small heating value in which a flow rate is low. Thus, the mixed air of a combustion air and a fuel steam can be completely mixed. Further, the central body 7 is red-heated by flame, so that the flame holding and combustion reaction of this central body 7 are effectively urged upon combustion at a low heating value where the temperature of flame is especially lowered and an incomplete combustion is liable to arise. Thus, a low air ratio combustion and complete combustion at a turn-down ratio can be effected.
