“…In another separate study using jatropha pure oil (JPO) and jatropha biodiesel/ methyl esters (JME) conducted by the same group, it was reported that CO emission for JPO was higher than diesel and JME, whereas NO x emission was similar for all the fuel tested especially at fixed air flow rates. Another interesting finding was that increasing biofuel mixing ratio for JPO and JME with diesel resulted in reduced radiation intensity and soot emission (Hashimoto et al, 2014). Erazo Jr et al (2010) compared the emissions of canola biodiesel against diesel fuel using a spray flame burner.…”

“…The commonly used transesterification method produces fatty acid methyl esters by using alcohols (either methanol or ethanol) and provides a biodiesel product with a significant reduction in viscosity compared with the feedstock oil [44]. This reaction process is completed with a lower amount of the catalyst used (whether it is acid catalyst or alkaline catalyst) [45].…”

“…The specifications of the gas analyzer are listed in Table 3. are the concentration corrected to 16% O2 of species i (ppm), the measured concentration of species i in the exhaust gas (ppm) and the measured concentration of O2 in the exhausted gas (%), respectively [45]. This analyzing system of combustion products used the ENDA-5000 series stack-gas analyzer system by Horiba (Kyoto, Japan).…”

This paper focuses on the combustion performance of various blends of biodiesel fuels and diesel fuel from lean to rich mixtures. The biodiesel blend fuel combustion experiments were carried out using a liquid fuel burner and biodiesel fuel made from various plant oil feedstocks, including jatropha, palm and coconut oils. The results show that jatropha oil methyl ester blend 25 (JOME B25) and coconut oil methyl ester blend 25 (COME B25) blended at 25% by volume in diesel fuel produced lower carbon monoxide (CO) and unburned hydrocarbon (UHC) emissions due to more complete combustion. Overall, JOME B25 had the highest CO emission reduction, at about 42.25%, followed by COME B25 at 26.44% emission reduction relative to pure diesel fuel. By contrast, the palm oil methyl ester blend 25 (POME B25) showed a 48.44% increase in these emissions. The results showed that the nitrogen oxides (NO x ) emissions were slightly higher for all biodiesel blend fuels compared with pure diesel fuel combustion. In case of sulphur dioxide (SO 2 ) and UHC emissions, all biodiesel blends fuels have significantly reduced emissions. In the case of SO 2 emission, the POME B25, JOME B25 and COME B25 emissions were reduced 14.62%, 14.45% and 21.39%, respectively, relative to SO 2 emission from combusting pure diesel fuel. UHC emissions of POME B25, JOME B25 and COME B25 showed 51%, 71% and 70% reductions, respectively, compared to diesel fuel. The conclusion from the results is that all the biodiesel blend fuels are suitable and can be recommended for use in liquid fuel burners in order to get better and 'greener' environmental outcomes.

“…In the literature, several studies comparing the performance of fossil fuel fired gas turbine plants to bio-derivative fuels have been undertaken [10]- [13]. Kunte [11] investigated the opportunity of deploying either of biogas or syngas to fire a 200kW micro-gas turbine with a heat recovery steam generator, intended to reduce the carbon emissions from the thermal power plant.…”

This study compares the performance of a thermal power plant fired by natural gas to that fired by biodiesel blend, from exergetic and economic perspectives. A thermodynamic model has been developed to predict the performance of a running plant and was used to conduct the comparative study. Plant life of 25 years has been used to assess the viability of the gas turbine power plant by analyzing the net present cost and the break-even point for both fuels. The plant specific fuel consumption for natural gas fired and biodiesel blend fired are 0.3151[kg/kWh] and 0.3884 [kg/kWh] respectively. The system fired by natural gas only, has a payback period of 1.9 years, internal rate of return of 52% and exhaust temperature of 915.74 [K], while that fired by the biodiesel blend has a payback period of 2.4 years, internal rate of return of 60% and exhaust temperature of 858.50 [K]. Nevertheless, biodiesel blend is preferable because it is biodegradable, produces less emissions, and as a consequence, environmentally benign. Biodiesel blend would be more suitable for firing gas turbine engines, if the combustor is redesigned to improve its efficiency. Thermo-economic analysis of gas turbine power plants is essential to improve its thermodynamic and economic performance.
