NOx emission analysis and flame stabilization of ammonia-hydrogen-air premixed flames

Hadi NozariArif Karabeyoğlu

Based on its well-known merits, ammonia has been gaining special attention as a potential renewable energy carrier which can be replaced in power generation units. One of the major challenges with ammonia as a fuel is NOx emission, which has a complex underlying chemical kinetics. In an earlier chemical kinetics study by the authors, NOx formation sensitivity was thoroughly studied in a wide range of combustion conditions [Nozari & Karabeyoğlu, J.Fuel 2015]. As the next step, premixed ammonia-hydrogen-air flames are studied experimentally in standard temperature and pressure condition. Effects of some major influential parameters on NOx emission levels are investigated:…

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…

Japan's Fourth Strategic Energy Plan

Stephen H. Crolius September 19, 2016

The Cabinet of the Government of Japan adopted the country’s Fourth Strategic Energy Plan in April 2014. The Plan includes a Strategy for Hydrogen & Fuel Cells which is being executed by the Ministry of Economy, Trade and Industry (METI). The accompanying H2/FC Road Map includes an investigation of three materials that can carry the energy embodied in molecular hydrogen: liquid hydrogen, organic hydrides such as methylcyclohexane, and ammonia.

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…

Project Alkammonia: Ammonia-fed Alkaline Fuel Cells

Trevor Brown April 25, 2013

Following last year’s field trials of Diverse Energy’s PowerCube technology in Africa (and AFC Energy’s subsequent acquisition of assets from Diverse), an EU-funded project to commercialize ammonia-fed fuel cells for stationary power generation continues to gather momentum under the title “Project Alkammonia".
