  • Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism

    In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...

  • PureAire Combines Oxygen and CO2 Sensors to provide a Dual Gas Monitor to the Marketplace

    As a recognized leader in O2 safety monitoring, PureAire recently explored the need for an O2 monitor where carbon dioxide is used. There are four key cryogenic gases; nitrogen, helium, argon, and carbon dioxide (CO2), which can create an oxygen deficient atmosphere. Material Safety Data Sheets (MSDS) covering cryogenic gases cite that a cryogenic leak can create an unsafe ...

  • State of Oregon acquires CEREX micro hound multi-gas analyzers for hazmat first responders

    Abstract: "During the overhaul phase of a structure fire, firefighters commonly doff their self contained breathing apparatus SCBA protection for easier working conditions and traditionally rely upon carbon monoxide (CO) detection as the determinate for this action. A CO level of below 35 ppm has traditionally been the acceptable limit for firefighters to wear this lesser level of ...

  • 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.
