Abstract: An improved bulkhead for dual fuel industrial and aeroengine gas turbines, that may be formed by one or more bulkhead elements. Each element has a fuel-air channel, having an inlet for introducing air and an outlet for exiting a fuel-air mixture. Each element further includes at least one manifold for introducing a liquid or a gaseous fuel into the fuel-air channel. The channel and the manifold are formed by a plurality of etched layers of macrolaminate or platelet material. Each element may further include an air cooling channel for cooling the backside of the bulkhead. The bulkhead may be used in can and in annular combustors.
