Ignition Delay Times of Diluted Mixtures of Ammonia/Methane at Elevated Pressures

C. Filipe RamosBo ShuRavi FernandesMário Costa November 12, 2019

The present worldwide concern with global warming has stimulated the development of carbon-neutral energy technologies in order to mitigate the need of fossil fuels and the emission of greenhouse gases. In this sense, ammonia (NH3) is regarded as one of the most viable alternatives to produce carbon-free energy, presenting high energy density and ease of storage and handling [1]. Furthermore, due to the long-lasting use of ammonia in the fertilizer and refrigerant industries, its possible implementation as a fuel presents an unmatched economic feasibility, when compared to other carbon-free alternatives [2]. However, ammonia has proven to be more resilient to…

A demonstration test with the aim to show the potential of ammonia-fired power plant is planned using a micro gas turbine. 50kW class turbine system firing kerosene is selected as a base model. A standard combustor is replaced to a prototype combustor which enables a bi-fuel supply of kerosene and ammonia gas. Diffusion combustion is employed to the prototype combustor due to its flame stability. 44kW power generation was achieved by 100% heat from ammonia gas. Although NOx concentration in the exhaust gas of ammonia combustion exceeded 500ppm, NOx removal equipment reduced NOx concentration below 10ppm. Over 30kW power generation…
