چکیده
In recent years significant progress has been made in the development of market applications for hydrogen fuel use in gas turbines. These applications include integrated gasification combined cycle (IGCC) and other types of process/power plants. Development of a new application using gas turbines for significant reduction of power plant CO2 emissions has initiated extensive efforts to expand the range of hydrogen combustion capabilities. This paper reports on leading gasification systems producing hydrogen fuel, their technology background, and the results of a recent hydrogen combustion-testing program including resultant affects on gas turbine cycles.

Co2 Abatement by the Combustion of H2-rich Fuels in Gas Turbines
As a response to the threat of global climate change, a number of technologies have been proposed in which the carbon dioxide produced by combustion of fossil fuels at power stations is captured and stored. A leading option is based on the pre-combustion decarbonisation of fossil fuels to produce hydrogen-rich fuel gases. Such decarbonisation processes integrate the production of a synthesis ga...
متن کاملTheoretical study of the effect of hydrogen addition to natural gas-fueled direct-injection engines
The preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hy...
متن کاملExperimental Study of Hydrogen Addition Impact on Emissions and Performance of a Natural Gas Fueled Engine
Hydrogen is seen as one of the important energy carriers of the future with potential to reduce local as well as global warming. The main by-product of the combustion of hydrogen in air is water vapor and trace quantities of oxides of nitrogen. An experiment was conducted to study the impact of hydrogen/natural gas blends on performance, thermodynamic efficiency and exhaust gas emissions in ...
متن کاملEnergy and economic comparison of SOFC-GT, MCFC-GT, and SOFC-MCFC-GT hybrid systems
Conversion of fossil fuels to electrical power is the most popular method of electrical power generation. Due to the depletion of fossil fuels and the increase in air pollution, the necessity of using high efficiency power generation systems is increasing. High temperature fuel cells, such as solid oxide fuel cells (SOFC) and molten carbonate fuel cells (MCFC), have high efficiency. According t...
متن کاملOn Fuel Suitability for Gas Turbines
Industrial gas turbines allow operation with a wide variety of gaseous and liquid fuels. To determine the suitability for operation with a gas fuel system, various physical parameters of the proposed fuel need to be determined: heating value, dew point, JouleThompson coefficient, Wobbe index, and others. This paper describes an approach to provide a consistent treatment for determining the abov...
