“…Climate change, global warming and other detrimental impacts of combustion pollutants have mandated strong legislations and regulations in the future design of combustion systems and the choice of fuels [1][2][3][4][5][6][7]. The UK targets the 2050 net carbon zero-emission, thereby necessitating the decarbonization of both mobile and stationary combustion systems.…”

“…The choice of appropriate fuel nozzle, swirler, and a flame holder with enough air staging holes could lead to efficient mixing of the fuel and air and efficient combustion at different stages within a short period of time. The use of biofuels may put some limitations on the long-term operation of the MT (e.g., clogging in atomizer orifice, more CO emissions, turbine malfunction [23][24][25][26], reduction of static thrust [27], and vibration [28]), making it necessary to consider stringent revisions or even redesign in the precedent combustors that already operating well in the MT assemblies. Laranci et al [29] have shown that in the case of biomass-derived fuels the occurrence of high-temperature creep phenomena affects the liner walls leading to the high temperature oxidation damage.…”

The ever-increasing demand on highly efficient decentralized power generation with low CO2 emission has made microturbines for power generation in micro-combined heat and power (mCHP) generation systems popular when running on biofuels as a renewable source of energy. This document presents a state-of-the-art design, and optimization (in terms of design, performance and emission control) of a micro-turbine renewable energy combustor that fits into the existing Bladon 12kWe recuperated microturbine plenum while running on a range of biofuels as it can successfully provide the required power of the mCHP. Governing equations for in-depth analysis of the combustor consist of manufacturer empirical data to simulate system-level operation with respect to replacement of the fossil with biofuels. The Model developed and validated at company's ISO conditions confirms the output power of the new combustor fits the conventional system with slight eco-energy improvements. The modeling of the combustor in a complete microturbine assembly system is performed, then was utilized to further analysis of the microturbine with the designed combustor. The experimental results gave on average 46.7% electrical efficiency, 83.2% system efficiency, 12 kWe electrical power, and 90% recuperator effectiveness at nominal operating conditions of microturbine (MT). Sensitivity analyses evaluate changes in performance with respect to fuel phase (e.g., liquid or gaseous) and design variables (e.g., orientation, shape, and dimensions of combustor), leading to energy optimization of the unit.Experimental findings demonstrate that the combustor in microturbine can meet the target performance specifications of a company conventional diesel microturbine with significant savings. An objective function including both combustor and recuperator technical energy data is defined for finding the best ratio of fuel and air and their flow rates to find the most effective operating points for the operation of MT. Annual time series simulations completed for Coventry, West Midlands, United Kingdom indicate a new combustor can reduce operational costs of diesel 3 fuel combustor by 8%, 2%, 36%, and 25% when supplying bioethanol, DME, biogas, and NG, respectively. Annual operating time of the renewable microturbine combustor at rated capacity included an 11% reduction in exergy loss with biogas fuel relative to diesel fuel.

The residential sector is responsible for approximately 40% of final energy consumption in the European Union, being a potential target to increase energy efficiency and improve urban air quality. New high-efficiency heating oil boilers have been developed requiring fuel adaption by diminishing the sulfur content in the fuel. The present work has led to the conclusion that further fuel development, including the use of alternative fuels, may be directed to reduce fossil fuel consumption and decrease the formation of pollutants. Specific fuel properties, such as distillation curve and nitrogen content, show an influence on pollutant emissions, especially NO x , which can be reduced below the lowest limit required for gas domestic boilers, which, until now, set the state of the art in terms of NO x emissions. The addition of renewable fuels in heating oil formulations, contributing to a global CO2 decrease, does not affect the reduction in NO x emissions as far as it does not affect the nitrogen content and distillation curve of the fuel. Besides, a map of NO x emissions, useful to predict NO x emissions from the latest generation heating oil boilers, independent upon the type of fuel, has been inferred, and an equation has been proposed to guarantee low NO x emissions depending upon fuel properties.
