Abstract (en)
[origin: EP2503242A2] The head has a base plate (113) provided with a centric recess in which a burner is arranged. The plate is connected to walls of the combustion chamber and with a burner seal (116) that seals the burner towards a rim of the recess. The burner seal is arranged upstream of the plate and brought into contact with a collar (118). The collar is provided on the plate, and forms the rim of the recess. The seal has a holding element (117) that is formed as a sheet ring and arranged upstream of the seal, where the element is engaged with a projection (114) of the plate in a tension-free state.
