Mitsubishi Power has announced the development of single and mixed-fuel ammonia combustion boilers for industrial applications. Successful tests have been completed mimicking conditions in coal-fired boilers in thermal power stations. Ammonia-coal co-firing and pure ammonia fuel were investigated.

Importantly, Mitsubishi also announced that optimal conditions for ammonia combustion have been successfully identified during the testing:

These tests confirmed that flames remained extremely stable during combustion, as NOx emissions were as specified by the basic combustion test target, and there were (sic) no residual ammonia.
