Japan started to develop a low-NOx hydrogen gas turbine

Hundreds of MW Hydrogen Burning Gas Turbine Burners

NEDO announced on July 5th, 2016 that it has begun to develop basic technologies for low-NOx dry-type gas turbine combustors without reducing the efficiency of power generation. The target is after 2030. To achieve practical level. In addition, NEDO will also refresh its investigation and research system aimed at achieving the blueprint of hydrogen society, and strive to formulate a more detailed blueprint and strategy for technological development.

Currently, NEDO is advancing its goal of fully utilizing hydrogen energy in the future, advancing “leadership research and development projects such as hydrogen utilization,” and developing basic technologies in hydrogen production using renewable energy and hydrogen storage and transportation using energy carriers. . NEDO has newly added a dry hydrogen gas turbine burner project to its development projects. The research period of this project is from 2016 to 2017.

Among them, in the "Research and Development of Dry Low NOx High-Temperature Gas Turbines Supported by Hydrogen Special-fired Boilers", in order to develop hydrogen-specific burn-drying low-NOx burners that can be used in large-scale gas turbines of several hundred MW-class power generation enterprises, a porous coaxial spray will be developed. Development of technology such as large-scale high-temperature flow burners and evaluation of combustor properties. The goal is to study the feasibility of the burner's construction, perform analysis and design of the scale model burner, optimize the shape of the flame, achieve stable combustion, and achieve low NOx. The planned commissioned parties are Mitsubishi Hitachi Power Systems and Mitsubishi Heavy Industries.

In the "Research and Development of Hydrogen Gas Turbine Combustion Technology", we will use the hydrogen gas turbine power generation for self-use power generation of several MW class as its object, and research and develop its key component - a hydrogen-fired low-NOx burner. Among them, computational fluid dynamics (CFD) analysis will be used to predict the flow and combustion gas distribution and to study the burner shape. Afterwards, the high-pressure hydrogen combustion test will be performed on the designed and pilot burners with the goal of achieving stable combustion under low NOx conditions. The commissioned party is Kawasaki Heavy Industries.

In the aspect of "Investigation of the overall system import prospects", the results of past investigations and researches will be continued and developed, and these results will be rooted in theoretical technological innovation and social and organizational rationality, thereby clarifying hydrogen energy in the entire energy source. The positioning in the system will also present specific examples of import patterns, clearly positioning the technologies under development and focusing on the technologies to be strengthened in the future, and these measures will lead to the refinement of the blueprint for realizing the hydrogen society. Scheduled commissioners are Tokyo Institute of Technology, the Japan Industrial Technology Research Institute, and the Japan Institute of Energy Integration Engineering.

Carbon Glass Tube between Full Carbon Fiber Tube and G10 tube. 

Carbon Glass Fiber Tubes flexible than Full Carbon Fiber Tubes. However, heavier than full carbon fiber tubes.

Carbon glass fiber tubes have the same finish as the full carbon fiber tubes.

And the cost will less than full carbon fiber tubes.
