A combustor, or burner section, of a gas turbine engine made up of several individual cans. These cans are long and cylindrical and consist of an outer casing within which there is a perforated stainless steel combustion chamber liner, or inner liner. These combustors are arranged radially around the engine axis. Compressed gases from the compressor flow through the cans, where fuel is sprayed and burned to add energy. Cooling air flows between the housing and the inner liner and through holes in the inner liner to keep the temperature of the cans low enough to avoid any damage. These types of combustors have given way to annular or canannular combustors.
