To provide a thick and thin fuel combustion burner capable of sufficiently achieving mixing promotion of fuel gas and air in an inlet passage and diverting a fuel-air mixture of uniform concentration, for mixing the fuel gas and air separately supplied into the one inlet passage, in the inside, and then diverting and supplying the fuel-air mixture to a plurality of parts.
To a thick fuel-air mixture inlet passage 38 into which a jet flow of fuel gas is supplied on the center axis and an air flow is supplied on the outer peripheral side, respectively, a mixing promotion segment 39 is provided which is comprised of a narrow segment 391 formed by a front surface wall 393, a passage wall 394, and a back surface wall 395 protruded respectively from both sides in the width direction and an occluded section 392 at a lower end of a passage portion between passage walls on both sides. An inner width of a passage portion includes a projection area portion of a front end nozzle of a gas nozzle. Front surface walls 396 and 393 are both inclined, and the front surface wall 396 is offset to a downstream side and is loosely inclined.
