PURPOSE:To make it possible to maintain the same state of combustion and same shape of flames as during rated combustion even when the combustion rate was lowered. CONSTITUTION:The device comprises primary atomizing chambers 5 and secondary atomizing chambers 11, said secondary atomizing chambers 11 being defined by a primary atomizing tip 2 including the primary atomizing chambers 5 each of which has at its fore end a primary jet 6 and connected to a fuel inlet 3 opening into fuel passage F and an atomizing agent inlet 4 opening into atomizing agent passage A, an adjusting tip 7 consisting of a strut 8 provided at the front of the axial core portion of the primary atomizing tip 2 and a head portion 9 spreading like an ambrella, and a burner case 1 mounted over said primary stomizing tip 2 and adjusting tip 7. Also, multi-direction reflection grooves 10 are provided in the rear face of the adjusting tip 7 at the position where the jet flow from the primary atomizing chambers 5 is intercepted, and uniform slit-like jets 12 are formed by the whole peripheral face of the head side portion of the adjusting tip 7 and the whole inner peripheral surface at the end of the burner case 1. |
