Impact of ammonia as a fuel / co-fuel on NOx emissions
Ammonia is a hydrogen-based, carbon-free energy carrier. It has good energy density (22.5 MJ/kg) and can be liquefied (about 10 bar at 298 K). With the increasing demand to lower the CO2 emissions worldwide, pure ammonia combustion or co-combustion with a conventional fuel is an alternative solution in turbines, gas engines, power plants, furnaces, and cement kilns. The major challenges with the use of ammonia as a fuel are lowered heat flux and increased NOx emissions. These parameters were analyzed in Linde’s lab-scale tests with pure ammonia as well as mixtures of ammonia and natural gas. Tests were conducted with…
