アンモニア燃焼ガスタービン発電用の低NOx燃焼器開発のための試験設備

抄録

Ammonia is focused as a hydrogen energy carrier and carbon free fuel. National Institute of Advanced Industrial Science and Technology (AIST) collaborated with Tohoku University successfully performed an ammonia combustion gas turbine power generation in 2015. However, the weakness of the facilities was that they required large-size Selective Catalytic Reduction (SCR) equipment in order to suppress a high concentration of NOx. Although NOx reduction in the combustion process is desirable, low NOx combustion technology is difficult because ammonia had been thought of as a source of fuel-NO. AIST prepared a combustor test rig to test combustor alone without a compressor or turbine. Sharing with a 1-ton ammonia cylinder, a vaporizer and a gas compressor, combustor test rig was added two engine compressors, air surge tanks, and a high temperature SCR. A regenerator was used to preheat combustion air. Combustor test rig can achieve the same combustion condition as the gas turbine that was successfully demonstrated.
