More Information
Summary:A gas turbine combustor includes a fuel supplying section and a combustion tube. The fuel supplying section supplies fuel to a combustion zone inside the combustion tube. The combustion tube passes combustion gas to the turbine. The combustion tube is provided with a first region where an air passage for cooling air is formed and a second region where a steam passage for cooling steam is formed. The second region is located downstream of the first region in a direction of a mainstream flow of the combustion gas.
