Abstract
Gas turbine engine are one of the major prime movers used in industry and aviation to produce energy and power. However, a major limitation of gas turbine engines, in relation to climate change, is that they are mostly powered by fossil fuels which when burnt, release emissions in varying amounts into the atmosphere. Growing evidence worldwide, suggests that emissions from fossil fuels could be a major contributor to global climate change. As a result, various emission policies and goals, aimed at mitigating the effect of climate change are on the increase. Current trends in emissions policies tend towards potential for future taxation of emissions by any system capable of generating emissions. Therefore, current technologies, systems and procedures must be ready for potential changes in future economic climate due to changing environmental policies.
In this study, an emissions model is developed which evaluates the emissions generated and any potential emissions tax payable on emissions generated by a gas turbine engine over an operating horizon. The developed approach applies gas turbine information on fuel type, considered emissions and adopted emissions control to estimate the amount of emissions generated by a gas turbine. As a validation to the estimating methodology, the developed emissions model is applied to evaluate the known emissions rate for some gas turbines. Comparison of emissions model estimates with recorded values from the U.S. department of energy and the California energy commission reveal a difference of less than 3%.
