  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • The invisible fine dust

    Air is lifeblood. Daily we inhale approximately 15.000 liter. Still, the air contains invisible pollutants, which vary in its composition and concentration depending on the location. Especially the respirable particles with a diameter of less than 2.5 µm (PM 2.5) were considered to be particularly dangerous. According to a current study conducted by the Max Planck Society, ...

  • Dust monitoring

    Generally, two different approaches are used to measure the amount of dust deposited on a surface; Determination of the soiling of a surface, by a change in its properties; Determination of the quantity of dust deposited, by weight. WHAT IS DUST? Dust is a generic term used to describe fine particles that are suspended in the atmosphere. Dust comes from a wide variety of sources, including soil, ...

  • Dust Suppression With Gravelpave2

    Use of Gravelpave2 for pavement surfaces to restrict dust is a very viable suggestion, provided careful selection of the fine gravel fill is followed. Dust from gravel surfaces is created when vehicles pass over the surface - greater speed = greater dust and higher into air. Most gravel surfaces will have a wide range of particle sizes - from 1" to <200 screen (clay and silt sizes) or "dust". ...

  • Simultaneous determination of PM fractions, particle number and particle size distribution in high time resolution applying one and the same optical measurement technique

    Abstract The Fidas fine dust monitoring systems comprise an optical aerosol spectrometer, which is characterized by very good instrument characteristics, and utilize a sophisticated approach to convert the measured information on particle number and particle size into mass concentrations. As monitoring of PM requires reliable and quality-controlled performance of the measuring systems, ...

  • Dust collection dilemma: ostrich egg dust

    Rick Peil from the Toolking Superstore was presented with an interesting dust collection dilemma. Tamera Seevers creates unique fine art out of ostrich eggs (www.tameraseeversstudio.com). Carving and finishing the ostrich eggs takes up to three months and creates a very fine, ostrich egg dust. Her problem was with her 1-micron bag on the dust collection system, the dust was still escaping into ...

  • Accumulation and distribution characteristics of platinum group elements in roadside dusts in Beijing, China

    The concentrations, distribution, and accumulation of platinum group elements (PGEs) were investigated in roadside dusts collected in four different foundational areas in Beijing during February to May 2010. The results showed that PGE levels in all samples were above the average upper crust values, with mean concentrations of 57.5 ng · g−1 Pd, 28.2 ng · g−1 Pt, and 9.8 ng · g−1 Rh, respectively. ...

  • How a wet dust collector can prevent a violent explosion (and more!)

    Explosive dust is a major concern among metal finishing operations, and recent changes in the National Fire Protection Association regulations have made compliance more difficult. Metalwork grinding and sanding produces a fine metallic dust that, even after being filtered from the air, can smolder, catch fire, or even explode violently if it’s exposed to a spark. Aluminum, lithim, ...

  • Energy recovery from the Exhaust gases of a Cyclone preheater tower - case study

    FOREWORD Advanced Cyclone Systems, S.A. (ACS) designed and supplied a Hurricane cyclone system for Duna-Drava Kft cement plant in Beremend, Hungary, (a member of the HeidelbergCement Group, the global market leader in aggregates), as part of an energy recovery project. To maintain the quality of the ground Pet Coke within the specifications in terms of ash content, ACS was contacted with the ...

  • Which Portable Dust Collector Is Right for Your Workplace?

    When it comes to clean air regulations and dust collection systems, then these are nothing new. However, the new thing is the pressure that is being put on the implementation of those regulations. Even the smallest of companies and shops go through expensive fines if they do not obey this rule. Small areas may not need air filtration frequently and may also not have the required space to install ...

  • Pneumatic powder injection technique as a tool for waste utilisation

    The problem of wastes in metallurgical and foundry industries is very important. The considerable amount of wastes is furnace dusts and other fine materials. At the Department of Foundry, the experiments with the use of pneumatic injection method were carried out to utilise these materials. The results of dusts injection into cupola, slag foaming with the use of powdered coal-furnace dusts ...

  • A quantitative approach to the traffic air quality problem: the traffic air quality index

    The Traffic Air Quality (TAQ) model is a simple tool to estimate traffic fine particulate emissions on roadways (g/km) and can be used for both real-time analysis and for localized conformity analysis (“hot-spot” analysis for nonattainment areas) as defined by 40 CFR 93.123. This paper is a follow-up to a study published earlier regarding the development of the TAQ model. This paper shows how ...
