Abstract

PURPOSE:To perform an efficient combustion of waste material having various kinds of dust with a difference in their specific weight by a method wherein a pivoting wall enclosing a mixing chamber formed in front of a secondary air chamber is pivotally rotated around a flame. CONSTITUTION:A mixing chamber 10 formed so as to cause both secondary air in a secondary air chamber 6 and a waste material H fed to be merged with the secondary air to be flowed near the flame 11 of the fuel is cooperatively arranged in front of the secondary air chamber 6 arranged outside of a primary air chamber 3, and further a pivoting wall 12 pivotally supported substantially around the flame 11 so as to recover the waste material H of the non-combustible material dropped at the bottom part of the mixing chamber 10 and return it to near the flame 11 is arranged near the front end of the outer wall 7 of the secondary air chamber 6. With this arrangement, when the waste material H is to be ignited, even if a relative heavy waste material H is dropped to the bottom part of the mixing chamber 10 while it is in a non-ignited condition due to its difference in specific weight, the waste material H is repeatedly scraped up under a rotating action of the pivoting wall 12 and so it may be spread repeatedly near the flame 11 and ignited.
