Experimental investigation of the effects of using biofuel blends with conventional diesel on the performance, combustion, and emission characteristics of an industrial burner

Abstract

liquid biofuels are one of the most widely utilized today, bioethanol and biodiesel are essential to the development and advancement of the industry. In this research, an experimental investigation of the effects of biofuel blends with diesel on pollutant emissions and combustion characteristics of a 350-kW industrial burner. Tested fuel blends were D100, D50B50 (50% diesel and 50% biodiesel by volume), D50B50E15 (50% diesel, 50% biodiesel, and 15% bioethanol by volume), and D50B50E25 (50% diesel, 50% biodiesel and 25% bioethanol by volume). The equivalence ratio was adjusted to five values by varying the air flow rate and maintaining the fuel flow rate constant at 0.14 l/min.CO, HC, soot, and NOx were measured. Also, flame temperatures were recorded at different positions. The result indicates that utilizing the fuel blends D50B50, D50B50E15, and D50B50E25 reduces CO by (about 19, 69, and 65%), HC by (about 18, 37 and 28%), and smoke opacity emissions by (about 8, 50, and 30%) respectively, compared to diesel fuel. On the other hand, NOx emission significantly rises at D50B50E15 and D50B50E25. In terms of combustion characteristics. Biofuel mixture D50B50, D50B50E15, and D50B50E25 increase exhaust gas temperatures by (about 2, 3 and 1%), and maximum gas flames (about 5, 9 and 4%) respectively, compared to diesel. The ethanol percentage of more than 15% in the blends lowers the maximum flame temperature within the furnace and reduces the length and area of the flame. It is evident from this research that biofuel for industrial burners can produce optimum combustion characteristics and lower emissions.

Experimental Assessment of the Impact of Biodiesel Blends and Methanol on Emissions and Performance in a Semi-industrial Boiler

“…Furthermore, as the concentration of biodiesel in the mixture increases, there is a corresponding increase in the exhaust temperature. The greater oxygen content present in biodiesel can be attributable to this phenomenon when compared to standard diesel (Elkelawy et al, 2022) .…”

“…Veski (2002) stated that the optimal air-to-boiler ratio must be set in order to maintain maximal boiler efficiency. Elkelawy et al (2022) found that biofuel mixtures significantly reduced emissions compared to diesel oil alone. The CO emissions decreased by 19%, 69%, and 65% for D50B50, D50B50E15, and D50B50E25 fuels, respectively.…”

Experimental Investigation of the Biodiesel Direct Injection and Diesel Fuel as Premixed Charge on CI-Engine Emissions, Performance, and Combustion Characteristics

“…These equipment's' accuracy may be affected by the operating conditions and operating environment as this accuracy affects the limiting errors of the measurements. So, the uncertainty of measured and calculated parameters may be estimated by the following equations 1 & 2 [68][69][70]. The precision and uncertainty analysis for different equipment's was calculated and displayed in Table 3.…”

Experimental investigation of the effects of diesel-bioethanol blends on combustion and emission characteristics in industrial burner

“…Since fossil fuels are running out, have a lot of negative effects on the environment, and their prices are always changing, the industrial sector, which uses a lot of energy, needs fossil fuel alternatives right away. Because they come from a renewable source and are a sustainable fuel, biofuels are regarded as one of the best alternatives to conventional fuels [1,2]. In the past few years on a global scale, the Interest in the use of alternative fuels, particularly those produced from biomass residue through fermentation techniques, has increased [3,4].…”
