ABB will be exhibiting its latest range of air and gas analysers at the Air Quality and Emissions (AQE) Show at the Telford International Centre (22nd-23rd April 2015). Stands 70 and 71 will feature a comprehensive selection of ABB equipment including laser, zirconia and FTIR spectrometry. A main feature will be ABB’s new ACF5000 hot/wet extractive continuous emissions monitoring system for combustion applications. Using FTIR technology, the ACF5000 enables simultaneous analysis of up to 15 different gas components including SO2, CO2, CO, NH3 and VOCs using a single sample probe system.
Completely self-contained, the ACF5000 offers a turnkey solution for combustion process monitoring in municipal and hazardous waste incineration and power plants using coal, oil or waste. The system is also currently undergoing MCERTS certification for use in process plants for applications including DeNOx and DeSOx plant optimisation and HCL scrubber monitoring.
Other products on show will include the stand-alone LS4000 laser gas analyser system for use in hazardous locations. Enabling in-situ monitoring of stacks, pipes, process chambers and other similar applications, the LS4000 uses tunable diode laser absorption spectroscopy (TDLAS) to provide direct measurement of hazardous gas streams. Offering a very fast response time, the LS4000 is especially suited to high pressure, high temperature applications with fast changing conditions. Other equipment on display will be ABB’s Endura AZ20 zirconia oxygen and StackFlowMaster instruments.
The AZ20 is a compact combustion gas analyser for high temperature applications up to 800°C. Manufactured using a new ceramic-to-steel bonding process, the AZ20 offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperatures, as well as offering a gas tight bond throughout its operating temperature range.
Its ability to withstand the impact of sulphurous and reducing atmospheres makes it suitable for use in arduous applications including sulphur recovery processes, crematoria and industrial and clinical waste incineration.
The AZ20 also features integrated advanced calibration technology, which automatically controls both the test gas flow rate and test gas sequences during calibration testing. This eliminates the need for expensive ancillary equipment typically needed for traditional flue gas oxygen analyser systems and prevents incorrect calibrations caused by the loss of test gas.
The StackFlowMaster is an in-situ device for measuring flows in stacks up to eight metres in diameter. The StackFlowMaster manual version is for use in applications with relatively clean gases such as gas fired combustion processes. The StackFlowMaster automatic version features a purging and auto/span zero capability, making it suitable for applications with dust-laden gas streams. Both versions of the StackFlowMaster work with continuous emissions monitoring analysers to calculate the emissions flow in mass or corrected volume units of measurement.
As well as being MCERTS-certified and fully compliant with EN 15267-3, the StackFlowMaster is also fully QAL3 compliant, making it ideal for use by plants operating under an Environment Agency permit.
Using the StackFlowMaster’s zero and span functions, operators and test laboratories can perform regular tests to ascertain the performance of the analyser during normal operation.
Joining these products will be examples from ABB’s EasyLine EL3000 range of photometers for gas analysis. Based on ABB’s MCERTS-approved extractive continuous gas analysis technology, the EL range is available in both infrared (IR) and ultra-violet (UV) photometers, with a choice of sensing and analyser options including electrochemical, paramagnetic, thermal conductivity and trace oxygen.
Key features of the EL3000 range include automatic calibration and extensive self-diagnosis functions, including error messages in multiple languages, together with a simple menu-driven operator interface.
The EL3000 range is suitable for a wide variety of applications, including combustion processes, landfill gas monitoring, ambient air monitoring and emissions measurement in line with the Large Combustion Plants Directive 2001/80/EC.
As well as showcasing its products at the exhibition, ABB will also be hosting a workshop covering key issues affecting the deployment of gas analysers in industrial applications.
The workshop, hosted by ABB’s analytical product manager, Günter Haberzettl, will be entitled ‘Obtain the highest availability in emission monitoring with extractive operating CEMS’ (12.00 – 12.30pm, April 22nd, room 2; 12:00 – 12:30pm April 23rd, room 4). The workshop will explain how implementing a QAL3 evaluation tool into a continuous emissions monitoring system can help simplify data storage and reporting, with users able to access data via a web browser.
