The Green Growth Strategy to achieve carbon neutrality by 2050 has been established by the Japanese government and sets forth a "roadmap" for the growth of the fuel ammonia industry. In connection with this, ammonia fuel conversion in coal-fired thermal power generation has been positioned as a future initiative. Mitsubishi Heavy Industries, Ltd. is developing technology for fuel conversion to ammonia for both circular firing and opposed firing systems of coal-fired boilers in response to the needs of various customers in Japan and overseas. This paper reports the completion of the development of ammonia single-fuel burners and the prospect of their application to actual boilers, and provides an outline of the modification plans of a boiler plant for ammonia fuel conversion.
