Combustion chamber arrangement for vaporizing burner of e.g. pre-heater in vehicle, has chamber, where burner wall and/or fastening portion of chamber have fastening structures comprising profile with diameter increasing in axial direction
The arrangement (1) has a combustion chamber (4) surrounding a combustion space (10) for combustion of fuel with combustion air, and a burner rear wall (2) defining a rear side of the chamber. The chamber is connected with the rear wall such that a fastening portion (4a) of the chamber encompasses an external periphery of a region of the rear wall. The rear wall and/or the fastening portion have rotary fastening structures (2a-2C) spaced from each other in an axial direction of the arrangement. The fastening structures have a profile with diameter increasing in the axial direction.
