Abstract

A combustor transition can be adapted to guide combustion gases in a hot gas flow path extending between a combustor and a first stage of a turbine in a gas turbine. The combustor transition includes a duct having an upstream end adapted for connection to the combustor and a downstream end adapted for connection to a first stage of the turbine. The downstream end comprises an outer wall, an inner wall, a first side wall and a second side wall. At least one side wall has a side wall extension, which can extend in a downstream direction beyond the outlet. A gas turbine can be retrofitted with such a combustor transition and a gas turbine with such a combustor transition can also undergo a borescope inspection.
