Abstract

PURPOSE: To reduce the generation of NOx and CO control of the supply of a secondary air by a proper control of the combusion temperature through the regulation of a secondary air to be supplied.
CONSTITUTION: After fed into a pre-mixing chamber 3 through an inlet 7, a mixed gas held within the inflammability limit forms an inner flame 9, the moment it flows out through a flame hole 4. The outer flame section thereof receives a secondary air from an air hole 5 to complete the combustion, thus checking the generation of NOx. In such a combusion of a secondary air passage 5 is formed into a triangle, while the lower end 5a of the hole 5 is oriented to the direction of the flame from the passage 6 and located at a proper point on the plane a-b extending along the direction. With such an arrangement, the inner end of the hole 5 is divided into planes a-b and b-c, thus providing two flames jetting at the right angle to the respective planes. In addition, since the flame through the hole 5 on the side of the plane a-b is jetted slower due to the greater length of the hole than that on the side of the plane b-c, a dispersed feed of the secondary air into the outer flame can be done, thus reducing the generation of CO
