Abstract
This burner comprises a gas distributor (20) with a row of gas injectors (5a to 5e), the tube being axially inside an air distributor tube. Each gas injector extends through the wall of the air distributor tube via a coaxial air outlet aperture. The gas distributor tube includes two sealing bodies (36, 37) sliding symmetrically on either side of a central gas inlet aperture (21). Each of these bodies is provided with an eccentric longitudinal threaded bore (38, 39) engaging a threaded section of a rotating control rod (41). The two sections (48, 49) are threaded in opposite directions to the thread of the sealing bodies (36, 37), which enables them to move these two sealing bodies simultaneously in order to gradually interrupt or restore the supply of gas to the injectors (5a to 5e) situated at the end of the row without interrupting the supply to the air injectors.
