ABSTRACT

Coal-fired power generation is supplying about 30% of the world’s primary energy. Almost all of coal-fired power plants in Japan employ the pulverized coal combustion method. In the pulverized coal combustion, coal is pulverized into a powder of several tens of microns. This method enables to burn coal effectively because of the large surface to volume ratio. Pulverized coal particles are supplied to the actual boilers with primary air whose Air/Coal ratio (mass flow rate of primary air/mass flow rate of pulverized coal) is set to 2.0. Co-combustion of coal with ammonia has been studied with the aim of reducing CO2 emissions in coal boilers and coal power plants in terms of a concept to use ammonia as a renewable fuel from solar, wind, etc. Continue reading →

ABSTRACT

To protect against global warming, a massive influx of renewable energy is expected. Although H2 is a renewable media, its storage and transportation in large quantity is difficult. NH3 fuel, however, is an H2 energy carrier and carbon-free fuel, and its storage and transportation technology is already established. Although NH3 fuel combustion was studied in the 1960s in the USA, the development of an NH3 fuel gas turbine had been abandoned because combustion efficiency was unacceptably low [1]. Recent demand for H2 energy carrier revives the usage of NH3 fuel, but no one has attempted an actual design setup for NH3 fuel gas turbine power generation. The National Institute of Advanced Industrial Science and Technology (AIST) in Japan collaborated with Tohoku University successfully performed NH3-kerosene gas turbine power generation in 2014, and NH3 fuel gas turbine power generation in 2015 [2].

AIChE Annual Meeting, Topical Conference: NH3 Energy⁺

ABSTRACT

Ammonia has the potential to contribute significantly to the decarbonisation of energy systems, by offering a practical, carbon-free hydrogen storage and transportation vector as well as a green fuel in its own right. To better understand the prospects and challenges surrounding the use of ammonia in energy systems, Siemens is leading a collaborative project to build and test an ammonia-based energy storage system at the Rutherford Appleton Laboratory in the UK. Together with its project partners (the UK Science and Technology Facilities Council, the University of Oxford and the University of Cardiff), and supported by Innovate UK, Siemens will demonstrate the full energy cycle of renewable power converted into ammonia and then back into electricity for grid export.

NH3 Fuel Conference, Los Angeles, September 19, 2016

ABSTRACT

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. Continue reading →
