举例来说,一项技术是通过风能将地下洞穴内的空气压缩产生电能;将空气输送至燃气涡轮机以提高燃烧功效。
One, for instance, uses power produced when the wind is blowing to compress air in underground chambers; the air is fed into gas-fired turbines to make them run more efficiently.
The invention relates to a gas turbine premixer with internal cooling. A system that includes a turbine fuel nozzle (144) comprising an air-fuel premixer (170).
