  • Analysing coloured smoke | Pearl or Quest?

    Coloured smoke consists of an aerosol of tiny particles which is combusted or vaporized. The particular pigment or dye of each colour affects the colour of the smoke. The mixture usually includes a cool-burning formula based on potassium chlorate oxidiser, dextrin or lactose as fuel. Then one or more dyes are introduced to account for around half of the mixture. A small amount of sodium ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Energy and exergy analyses of a spark-ignition engine

    In this paper, the performance of an internal combustion engine is evaluated at the steady-state condition by application of energy and exergy analysis using the experimental test results. The energy and exergy balances are calculated at different engine speeds. The results show that the heat rejection of energy and exergy flow increases with increasing engine speed. The exergy efficiencies are ...

  • Detailed chemical modelling of a flameless combustion turbine for pollution prevention

    Flameless combustion has been acknowledged as one of the most interesting combustion technologies to meet both the targets of high process efficiency and low pollutant emissions. The present investigation is concerned with the application of the flameless combustion mode to an adiabatic combustor, typically used in gas turbine engines. Detailed chemical kinetics calculations, by means of a ...

  • Decomposition analysis of CO2 emissions from fuel combustion in selected countries

    This article introduces an approach applicable to analysing different factors influencing elements relevant in sustainable development like environmental impacts. The approach is built on the idea of IPAT identity and it applies a chained two-factor decomposition technique for calculating numerical estimates for a larger set of contributing factors than traditionally done in applying ...

  • Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil

    The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been ...

  • Effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle

    This paper analyses the effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle under a temperature restriction as maximum. Amount of heat addition at constant pressure is defined as a function of fuel's energy with utilising the combustion efficiency. The amount of released energy into the cylinder restricts the compression ratio. Relations between the combustion ...

  • The effects of variable specific heats of working fluid on the performance of an irreversible Otto cycle

    The performance of an air-standard Otto cycle with variable specific heats of working fluid and heat resistance and friction irreversible losses is analysed by using finite-time thermodynamics. The relations between the power output and the compression ratio, between the thermal efficiency and the compression ratio, as well as the optimal relation between power output and the efficiency of the ...

  • Exhaust gas treatment by an atmospheric pressure microwave plasma

    A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

  • Exergy analysis of a steam power plant: a case study in Iran

    In the last decades, exergy analysis, based on the second law of thermodynamics was a method that substituted the energy analysis in studying thermodynamic systems. In this paper, the cycle of a power plant and its details, with two kinds of fuels, natural gas and diesel, have been analysed at its maximum load and the two factors, losses and exergy efficiency, which are the basic factors used to ...

  • Understanding the Interactions between Climate Change and Air Quality

    There is increasing evidence and scientific consensus that our world’s climate may be changing due to, among other things, fossil-fuel combustion, biomass burning, and forest and soil destruction. Scientific analyses suggest that, as a result of increasing greenhouse gas emissions, there could be substantial changes in seasonal temperature and precipitation patterns, which, in turn, could ...

  • Relationships among loss-on-ignition and unburned carbons, and the FTIR photoacoustic spectra of fly ashes

    Loss-on-ignition (LOI) and unburned carbon (UC) concentrations of fly ash are two very important indices for evaluating combustion efficiencies of boilers. They are also very important factors affecting the utilisation of fly ashes. The LOI and UC of five fly ash samples collected from different power plants were analysed. The Fourier-transform infrared (FTIR) photoacoustic spectra (PAS) of these ...
