Book Spray Combustion of Diesel Biodiesel Fuel Blends

Download or read book Spray Combustion of Diesel Biodiesel Fuel Blends written by Cristian Aldana Zambrano and published by LAP Lambert Academic Publishing. This book was released on 2011-12 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biofuels represent a group of emerging alternative fuels for current automobiles and aircraft engines. Soy methyl ester (SME) and Canola methyl ester (CME) are two such biofuels and are formed by the transesterification of soy oil and canola oil respectively. SME and CME, like other biofuels, are environmentally carbon-neutral, have no sulfur content, are locally produced and have diesel-like properties. The objective of this study was to characterize the combustion properties of spray flames of blends of SME and CME with No. 2 diesel fuel in a heated, co-flow air environment. The experiments were conducted maintaining fuel lean conditions at two different global equivalence ratios for each of the blends tested. Six different blends of SME and CME were studied. A partial swirl, air blast atomizer was used to create the spray. The global emissions from the flames were measured by collecting samples in the exhaust and passing the sample through a gas analyzer. Similarly, the in-flame species concentrations of CO, NO, CO2 and O2 were measure. In-flame temperature measurements were performed using an R-Type thermocouple and were corrected by radiation, convection and conduction.

Book Spray Combustion Characteristics and Emissions of a Wood Derived Fast Pyrolysis Liquid Ethanol Blend in a Pilot Stabilized Swirl Burner

Download or read book Spray Combustion Characteristics and Emissions of a Wood Derived Fast Pyrolysis Liquid Ethanol Blend in a Pilot Stabilized Swirl Burner written by Tommy Tzanetakis and published by . This book was released on 2011 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass fast pyrolysis liquid (bio-oil) is a cellulose based alternative fuel with the potential to displace fossil fuels in stationary heat and power applications. To better understand the combustion behavior and emissions of bio-oil, a 10 kW spray burner was designed and constructed. The effect of swirl, atomization quality, ignition source (pilot) energy, air/fuel preheat and equivalence ratio on the stability and emissions of bio-oil spray flames was investigated. A blend of 80% pyrolysis liquid and 20% ethanol by volume was used during the tests and the results were compared to burner operation with diesel. It is important to have good atomization, thorough mixing and high swirl in order to stabilize ignition, promote the burnout of bio-oil and decrease CO, hydrocarbon and particulate matter emissions. The total amount of primary air and atomizing air that can be used to improve turbulence, mixing, droplet burnout and overall combustion quality is limited by the distillable fraction and narrow lean blow-out limit associated with pyrolysis liquid. Air and fuel preheat are important for reducing hydrocarbon and CO emissions, although subsequent fuel boiling should be avoided in order to maintain flame stability. The NOx produced in bio-oil flames is dominated by the conversion of fuel bound nitrogen. The particulate matter collected during bio-oil combustion is composed of both carbonaceous cenosphere residues and ash. Under good burning conditions, the majority consists of ash. Pilot flame energy and air/fuel preheat have a weak effect on the total particulate matter in the exhaust. Generally, these results suggest that available burner parameters can be adjusted in order to achieve low hydrocarbon, CO and carbonaceous particulate matter emissions when using pyrolysis liquid. Total particulates can be further mitigated by reducing the inherent ash content in bio-oil. Comparative burner tests with diesel reveal much lower emissions for this fuel at most of the operating points considered. This is due to the fully distillable nature, better atomization and improved spray ignition characteristics associated with diesel. Because of its superior volatility, diesel can also operate over a much wider range of primary air and atomizing air flow rates compared to bio-oil.

Available in PDF, EPUB and Kindle. Book excerpt: With increasing concern on the dwindling of the fossil fuel reserve and climate change, more and more effort has been focused on seeking green fuel to replace fossil fuel and mitigating the emissions of greenhouse gas (GHG). Biodiesel has attracted much attention for its sustainability, lower emissions of HC, PM and CO, and the diverse feedstock. In this study, diesel/diesel-like fuels were experimentally studied in terms of spray and combustion characteristics.

Book Combustion and Emission Characteristics of Blends n Butanol Diesel D2 and Dual Alcohols N Butanol Methanol with Gasoline in Internal Combustion Engines

Download or read book Combustion and Emission Characteristics of Blends n Butanol Diesel D2 and Dual Alcohols N Butanol Methanol with Gasoline in Internal Combustion Engines written by Lennox Siwale and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the effects of oxygenated alcohol/gasoline/diesel fuel blends on performance, combustion, and emission characteristics in conventional reciprocating engines is reported. On the one hand, in alcohol-gasoline blends, dual alcohols-gasoline blends have not yet been sufficiently proven as suitable alternatives to single alcohol-gasoline blends in engines as far as performance is concerned. On the other hand, n-butanol-diesel, although it has a better miscibility factor in diesel than methanol or ethanol, is limited with regard to extensive application in the diesel engines due to its low cetane number. Engine performance was compared using single alcohol-gasoline and dual alcohol-gasoline blends, where the dual blends were constrained to meet the vapor issues regarding fuels and regulations. The blends were selected in terms of a combination by volume of one being higher alcohol (n-butanol) and the other, lower alcohol (methanol). The engines used for this study included a single-cylinder and a four-cylinder, naturally aspirated, four-stroke spark ignition engines and a four-cylinder, four-stroke compression ignition turbocharged diesel engine. In the n-butanol-diesel studies, a comparison was made with other studies in order to determine how suitable n-butanol-diesel blends were across the biofuel family such as the biodiesel-ethanol-diesel blends. The findings were as follows: The dual alcohols-gasoline blends performed better than the single alcohol-gasoline blends depending on certain compositional ratios of the alcohols in gasoline regardless of vapor pressure consideration. The n-butanol/diesel alcohol blend (B5, B10, and B20, where B5 represents 5% n-butanol and 95% diesel) significantly reduced the regulated emissions in a turbocharged engine compared to other studies using biodiesel-diesel blends. The significant decrease in NOx, CO emissions, and reduction of unburned hydrocarbons content using n-butanol/diesel fuel (DF) blends were found experimentally. The use of dual alcohol /gasoline blends was beneficial due to their shorter combustion duration in crank angles and their higher-energy content compared with single alcohol-gasoline blends. The n-butanol/diesel blend fired in the diesel engine showed a higher brake thermal efficiency and improved brake specific fuel consumption compared to the study by others where ethanol\diesel and methanol\diesel blends were used.
