摘要： A lance applicable to a boiler burner, the lance presenting a rigid shape. By means of the device disclosed herein, it becomes possible to carry out maintenance, assembly, disassembly and replacement of oil lances for boiler burners that are operational in places with limited space. The lance provided by the present utility model comprises a modular structure consisting of rigid elements, which allows achieving a correct positioning of the burner nozzle using this lance in relation to the boiler. Consequently, it is guaranteed that the boiler operates under ideal operating conditions, once the burning in the burner portion is controlled. For this purpose, the device disclosed in the present utility model comprises a hexagonal bar that provides the interconnection of a first tube to be interconnected with a second tube of greater diameter, wherein between the first tube and the second tube the arrangement of a sealing gasket is provided.
