AMETEK . PROCESS INSTRUMENTS A PRODUCT DATA SHEET MEASURES: O2, Combustibles WDG-HPIIC Flue Gas Oxygen and Combustibles Analyzer Close-coupled convective design for high-particulate applications The WDG-HPIIC is a direct-mounted combustion analyzer providing a continuous measurement of oxygen and combustibles in flue gas applications with high levels of particulate. It leverages a unique chimney-effect/convective sampling technology which offers the advantages of high-particulate sampling (typically characteristic of an insitu probe) with the high temperature and corrosion resistance of an extractive analyzer. The WDG-HPIIC is ideal for combustion optimization on applications in cement and lime kilns, foundry and metals production furnaces, power and steam boilers (coal, wood waste and heavy oil-fired) and black liquor recovery boilers. The analyzers can be provided with a separate Series 2000 controller and are offered in a range of mounting styles. Reliable The WDG-HPIIC leverages convective sampling and relies on diffusion of the sample, which reduces the velocity of gas to eliminate the problem of "sand blasting" the probe. In addition, the analyzer does not use an aspirator, minimizing particulate plugging up the inner sample plumbing. Accurate This analyzer utilizes the proven technology of zirconium oxide (ZrO2) for a net oxygen measurement. In addition, the catalytic detector measures combustibles within 0-2000 parts per million (ppm) for combustion optimization. Serviceable Maintenance can be performed on the WDG-HPIIC without removing it from the process.
