A silo combustion chamber for a gas turbine having a flame tube having an inner wall and flame tube base delimiting a combustion chamber; an outer wall surrounding the inner wall, forming a cavity; an annular chamber at least partly surrounding the outer wall and a number of supply lines fluidically
A silo combustion chamber for a gas turbine having a flame tube having an inner wall and flame tube base delimiting a combustion chamber; an outer wall surrounding the inner wall, forming a cavity; an annular chamber at least partly surrounding the outer wall and a number of supply lines fluidically coupled to the hot side of a heat exchanger during operation of the turbine; a number of burners, each of which opens into the combustion chamber on the outlet side through an opening in the flame tube base. The oxygen supply is fluidically connected to the annular chamber. A collecting chamber is arranged over the flame tube base. The annular chamber is connected to the collecting chamber via each connecting piece, each burner is fluidically connected to the collecting chamber to supply oxygen. The cavity between the inner and outer wall is locally fluidically separated from the collecting chamber.
