Abstract: PURPOSE: To reduce a thermal load of and at a harmful matter discharge value and a structural member by blowing off an additional air mass flow in a rear flow of a part of an insert to a combustion chamber located laterally with respect to a main flow at the front of an original combustion zone. CONSTITUTION: A fuel nozzle holder 8 and a fuel nozzle 9 have a plurality of outflow openings 6 and one passage both for an additional air mass flow 3 on a downstream side of a main flow 1. When the additional air mass flow 3 is blown out in front of an original combustion zone to make a spiral flow minimum, it is reduced or completely disappeared. As a result, an advantageous influence is provided to the rear flow at the insert 2 in the combustion chamber, and a harmful matter discharge value and a thermal load at a structural member are reduced.
