  • 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 ...

  • Ammonium, nitrate, and total nitrogen determination in fly ash

    Fly ash is a by-product of the combustion of pulverized coal and is composed of small particles. The composition of the fly ash may vary considerably, however, all fly ashes contain substantial amounts of silicon dioxide (SiO2), aluminum oxide (Al2O3) and calcium oxide (CaO). Nowadays, air pollution control standards require a separation of flue gas before being released to the atmosphere. Fly ...

  • Pressurised pulverised coal combustion ? a coal-based combined-cycle state of the cooperative project: cleaned flue gas matches specifications for use with gas turbines

    A high efficiency of 60% in a combined-cycle power plant technology with fuels like gas or light oil is estimated to be achievable. On the other hand existing conventional coal-fired power plants based on steam generation have an efficiency of about 40?45%. A huge potential of improvement in efficiency could be achieved by the implementation of a simple and cost-effective technology: PPCC, a ...

  • Why Are CHP Closing All Over The World?

    Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use ...

  • Potential agricultural uses of flue gas desulfurization gypsum in the northern great plains

    Flue gas desulfurization gypsum (FGDG) is a byproduct from the combustion of coal for electrical energy production. Currently, FGDG is being produced by 15 electrical generating stations in Alabama, Florida, Indiana, Iowa, Kentucky, Ohio, North Carolina, South Carolina, Tennessee, Texas, and Wisconsin. Much of this byproduct is used in the manufacturing of wallboard. The National Network for Use ...

  • Redundant combustion plant for Novartis

    Type     HOFGAS®- IFM4c/2200/1500/60/180 Commissioning     2004 Site     Novartis (Basel, CH) Situation In order to prevent production failure due to missing redundancy in the flue gas clean up, Novartis required an additional system. During different production processes exhaust air load with organic components is formed. ...

  • Capture of carbon dioxide from flue gas using solid regenerable sorbents

    Carbon dioxide emissions from the combustion of fossil fuels are a significant factor in global climate change. Large stationary sources such as coal-fired electric generating plants are likely to be the most cost-effective targets for carbon dioxide capture. At present, liquid amine-based scrubbing systems are the only processes available for this application. Processes based on regenerable ...

  • The Influence of PVC on the Quantity and Hazardousness of Flue Gas Cleaning Residues from Incineration

    The study estimates the influence of PVC on the quantity and hazardousness of flue gas residues from incineration. The analysis has been carried out on both theoretical and practical terms. A distinction between dry, semi-dry and wet gas treatment systems has been made. The influence of PVC has been assessed on the combustion steps and therefore on the distribution of chlorine and other ...

  • AMETEK THERMOX Introduces the WDG-V Combustion Analyzer

    Abstract AMETEK THERMOX Introduces the 5th Generation THERMOX Combustion Gas Analyzer in a CONTROL Magazine Exclusive. 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 well as CO and methane levels.  Information from the Gas Analyzer allows operators to obtain the highest ...

  • Flue gas Hg measurements from coal-fired boilers equipped with wet scrubbers

    The U.S. EPA has indicated they are considering additional SO2 and NOx emission reductions, and EPA is under a consent agreement to propose mercury reduction regulations by 2004 for the utility industry. The boiler manufacturers and the utility industry have developed improved combustion modification techniques to reduce NOx emissions. These advanced ...

  • Influence of Decreasing Heating Value on MSW Combustion

    Test runs in the TAMARA test facility to investigate the influence of decreasing lower heating value on the combustion of waste showed that the combustion quality could easily be kept constant at heating values exceeding 5 MJ/kg. The burnout of grate ashes and flue gas had slightly fallen off at lower heating values whereas the level of PCDD/F in the raw gas stayed constant in all tests. The ...

  • Application of combustion analyzers in safety instrumented systems

    The combustion process has always been considered having the potential for a hazardous event which could lead to personnel injury or loss of production. To mitigate this risk, the process industry is now implementing Safety Instrumented Systems which can identify hazardous operating conditions and correctly respond in such a way to bring the combustion process back to a safe operating condition ...

  • Corrosion Problems Arisen from the Use of Alternative Combustibles

    Introduction Metal Corrosion has been a subject of growing important in cement furnaces during the past few years. This development is mainly a result of the tendency to use alternative fuels with ...

  • A process for synthesising polymeric ferric sulphate using sulphur dioxide from coal combustion

    We propose a process that uses sulphur dioxide from coal combustion as a raw material to synthesise polymeric ferric sulphate (PFS), a water treatment agent. The process uses sodium chlorate as an oxidant and ferrous sulphate as an absorbent. Sodium carbonate is used as the regulator of the polymerisation process. The major chemical mechanisms in this reaction system include oxidation, ...

  • Advances in control of PM2.5 and PM2.5 precursors generated by the combustion of pulverised coal

    Particulate matter smaller than 2.5 mm in aerodynamic diametre (PM2.5) from coal-fired boilers is composed of directly emitted (primary) particles and particles formed from precursors (secondary particles). Technologies to reduce emissions of precursors to secondary PM2.5 emitted by coal-fired utility plants include wet and dry flue gas desulphurisation (FGD). Limestone forced ...
