  • The Goldilocks of Combustion Solutions

    It’s not too big, it’s not too small… It’s just right! We hear it all the time from our customers: “The ABUTEC 200 is too small for our site, but the HTF is too large. Can you create a custom unit?” The answer sometimes surprises those customers. While yes, we can certainly develop a custom unit just for your site, a more efficient (and cost-effective) ...


  • A structural decomposition analysis of air pollution from fossil fuel combustion in India

    During the last decade, there has been worldwide concern with global climate change, which has been induced by greenhouse gases (GHGs) due to the use of fossil fuels. The CO2 emissions from fossil fuel combustion have been identified as the single most significant source of GHG emissions into the atmosphere. Realising the need to control and regulate emissions of pollutants, the objective ...

  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • Exergy analysis of combustion characteristics and NOx emissions of a dual–fuel engine

    The combustion characteristics and NOx emissions of compression ignition engines working on a dual fuel mode are investigated numerically and their exergetic efficiencies are determined. The model has been validated with available experimental results. The simulation results show that dual fuel engine combustion and trend of NOx ...

  • Modelling and simulation with experimental verification of hydrogen-diesel dual-fuel premixed combustion and emission analysis

    This paper deals with an application of advanced simulation methods to the modelling of Duel-Fuelled engines (Hydrogen/Diesel) in which the premixed Hydrogen gas is ignited by the combustion flame initiated by a diesel spray. The model consists of a diesel auto-ignition model and a modified combustion model. The influence of main engine parameters i.e., injection advance, and various percentages ...

  • 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 ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Combustion and Thermal Behavior of Polyurethane Acrylate Modified with a Phosphorus Monomer

    A series of UV curable flame retardant resins were obtained by blending bis(2-acryloxyethyl) 2.6.7-trioxa-1-phosphabicyclo[2.2.2.]octane-4-methylol-1-oxide phosphate (MDMPE) in certain ratios with a commercial polyurethane acrylate (PUA). It has been found that the cured film shows good flame retardancy when the MDMPE is at 30% additive level. The cone calorimeter results show that the heat ...

  • Air pollution from electricity-generating large combustion plants

    The study was initiated in the context of the review of the Integrated Pollution Prevention and Control (IPPC) Directive. This report presents the results of a study that assesses the theoretical potential to reduce air emissions of SO2 and NOX that might have occurred had the best available techniques (BAT) and associated emission levels (AELs), as described in the large combustion plant ...

  • Two-Stage Combustion of High-PVC Solid Waste With HCL Recovery

    Untitled Document Abstract A waste-to-energy process based on high-PVC solid wastes is discussed. The basis is that at 200-400°C the PVC fraction decomposes ...

  • Second law analyses on oxy-fuel combustion of gaseous fuels

    The exergy losses in the adiabatic premixed oxy-fuel combustion are quantitatively analysed. The global exergy loss decreases with increasing equivalence ratio. The exergy loss of chemical reaction is comparable to that of internal thermal energy exchange for low equivalence ratio while that of mixing process is negligible. To keep similar thermodynamic characteristics of conventional combustion, ...

  • 5th-Generation Thermox WDG Flue Gas Combustion Analyzer

    "For more than 40 years, we have been a leader in combustion gas analysis," says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, "and we believe the WDG-V is the combustion analyzer of the future." WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as ...

  • Modeling Analysis of Fuel Sprays

    Current engine development processes in which computations play an important role have sought for numerical models which can accurately represent phenomena in spray combustion. The authors have developed original sub-models taking into account the effects of extensive spray combustion phenomena including nozzle cavitation, droplet breakup behavior, multi-component evaporation process, spray-wall ...

  • Exergy analysis of SI engines

    In this study, exergy (availability) analysis of a Spark Ignition (SI) engine has been performed theoretically during compression, combustion and expansion processes of the engine cycle. For this purpose, a thermodynamic-based engine cycle model is developed without considering the geometric features of fluid motion. Through the analysis, the effects of changing some design and operating ...

  • Techniques for Soot in Oil Analysis

    Since no engine is 100% efficient, products other than carbon dioxide and water will be formed during combustion. One such product produced from incomplete combustion is soot. Soot is a mass of mainly carbon particles that are typically spherical in shape. As soot levels rise, the soot particles begin to clump together and ...

  • Analysis of Motor Vehicle Exhaust Emissions

    A standard Hiden HPR-20 was used for the detection of various gaseous emissions from a motor vehicle. The mass spectrum was complex due to the mixture of air, hydrocarbons and other combustion products. Analysis of this type is important to detect levels of toxic or hazardous species. Such levels are often strictly controlled by local government legislation thereby forming an important target for ...
