  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • Understanding the dangers of combustible dust

    Paper shredding is growing into a big business. Recycling and the green movement certainly planted the seeds, but regulators have added the fertilizer. Industry-changing laws have been passed to govern document security in accounting, healthcare and banking, and shredders of many varieties are becoming the tools of those trades.Five or six years ago Warde Comeaux knew only a few people who ...

  • Combustion Of Heavy Fuels And Liquid Wastes

    This paper describes the design and operating conditions of liquid and gas combustors for heavy fuels and liquid wastes. Lower fuel prices can be achieved by switching from light oil to heavy ones, or combining with unconventional waste fuels. Unconventional waste fuels such as energetic off gases and organic liquid waste require especially designed combustion equipment like a special combustor ...

  • Size reduction of substitute combustibles (RDF)

    The new pilot installation of SITA Wiebe GmbH, Bielefeld/Germany, processes highly calorific commercial and industrial waste to become quality-assured substitute combustibles for cement industry and/or power plants. Basic items of this ultra-modern processing installation are two one-shaft size reduction machines of type WLK 30 Super-Jumbo of WEIMA Maschinenbau GmbH, Ilsfeld. The total output of ...


  • 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 ...

  • 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 ...

  • 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 ...

  • Cleaning biogas with bacteria

    Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid ...

  • Cleaning mold containing surfaces

    Once a determination is made that a moldy surface can be cleaned instead of removed or demolished, what cleaning agents are effective in removing or killing the mold? Many factors influence the selection of a cleaning agent. 1). The type of surface to be cleaned: Is it porous? Hard such as cement or sheetrock? Soft, such as cloth, fabric or wallpaper? Absorbent and thick such as rugs, ...

  • Super Clean Dream Machine

    It almost seems a certainty now: the electric car is set to conquer the developed world. But who will be the winners and losers in this exciting new race? Electric utilities and battery manufacturers are “in”, oil companies and sluggish car manufacturers are “out”. Large car manufacturers lobbied in Brussels for years to keep CO2 emission standards down – with some success. The standard to be met ...
