  • Testing the Performance of a DeNOx System Using a Portable Emissions Analyzer - Case study

    Using Portable Emissions Analyzers to Measure the Performance of a NOxReduction System in a Power Plant Boiler The majority of power plants utilize NOx reduction systems (eg. Ammonia Injection, SCR, etc.) in their power boilers to ensure that the NOx emissions levels comply with current regulations. The frequent evaluation of the ...

  • Forklift Emissions Analyzers

    Forklifts are commonly used in warehouses of various size and capacity for the movement and shipping of goods; however, the unoptimized engines can produce excess quantities of silent and deadly CO gas that can risk the health and safety of the workers. When forklifts are brought in for service usually the CO gas isn't measured. If the CO gas isn't measured and the engine properly optimized then ...

  • Siemens analyzers provide the accuracy needed for critical engine emissions testing – Case Study

    Challenge A company in the Western USA provides industrial gas turbines for both on- and offshore electrical power generation. The company offers low-emissions products and was looking for an analyzer to use in their continuous emissions monitoring (CEM) system that could accurately and continuously monitor and verify the CO emissions from their turbine’s gas engines. ...

  • Solutions for Automotive Testing

    In recent years, the field of research, development and testing of vehicles has created a need for integrated testing systems which cover the entire vehicle including engine and driveline. These systems also need to be capable of being deployed globally in a supportive structure. As a means of responding to these market requirements, building on our strengths in vehicle emissions measurement ...

  • Interpreting the IPCC emissions scenarios

    This paper discusses how two sets of emissions scenarios, generated using the Atmospheric Stabilization Framework, were used by the United Nations Intergovernmental Panel on Climate Change (IPCC). In particular, it discusses how the scenarios were specified, what roles models played in developing the scenarios, and how the scenarios were interpreted by participants in the IPCC process. It draws ...
