Numerical investigation of combustion characteristics of ammonia-air mixtures under high pressure lean conditions

Hadi Nozari Arif Karabeyoğlu

In this numerical study we investigate the combustion characteristics of ammonia-air mixtures at elevated pressure and lean conditions which are encountered in gas turbine combustors. The Konnov mechanism is implemented to predict the laminar burning velocity, autoignition, species concentrations and the sensitivity analysis of ammonia decomposition and laminar flame speed. A laminar premixed freely propagating flame model is implemented to calculate burning velocity, mole fractions of species, and contribution of reactions in molar conversion of specific species. Also a homogenous reactor model is used to analyze the temporal mole fraction of radicals and ignition delay time. Effects of adding hydrogen…

Micro Gas Turbine Operation with Kerosene and Ammonia

Norihiko Iki Osamu Kurata Takayuki Matsunuma Takahiro Inoue Masato Suzuki Taku Tsujimura Hirohide Furutani

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 with 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. Demonstration test of co-firing of kerosene and ammonia gas was achieved to check the functionality of the each component of the micro gas turbine. The gas turbine started firing kerosene and increased its electric power…

Using Local Green Energy and Ammonia to Power Gas Turbine Generators

Brian Evans

Beginning in the 1950s, a fundamental shift in the way information was electronically expressed and manipulated led to the “digital revolution” that has transformed — is still transforming — information systems and many major industries and that has given rise to the internet, social media, and instant very-low-cost communication (like this website). A good case can be made that a similar “revolution” is beginning — has already begun — to transform the energy systems upon which we all depend. This presentation will address the use of anhydrous (water-free) ammonia, NH3, as a realistic option for making a fundamental shift in…
