New Combustion Gas Analyser Delivers Industry Solutions in Extreme Environments

Building on the success of the acclaimed Fluegas 2700 combustion gas analyser, the SERVOTOUGH FluegasExact integrates Servomex’s (UK) unique Flowcube flow sensor technology to give users even more confidence in their combustion gas measurements.

Armed with an integral sampling system, custom-designed for operation in some of the hottest and most extreme combustion environments, the FluegasExact is the analyser of choice for the most demanding hydrocarbon processing and power generation applications.

At the heart of the SERVOTOUGH FluegasExact’s exceptional performance are Servomex’s patented zirconium oxide cell for oxygen measurement and a thick film catalytic sensor for measuring carbon monoxide and COe combustibles.

Able to measure oxygen on a wet basis, the FluegasExact’s advanced zirconia technology requires no external sample conditioning system, while minimal calibration requirements and a long operational life of up to ten years ensure reduced maintenance costs. The FluegasExact’s thick film calorimeter technology monitors CO levels with high precision, giving sufficient sensitivity and speed of response to enable the combustion process to be continuously optimised for increased process safety and efficiency. Combined, the performance of both technologies improves flame stability, reduce NOx, SO3 and CO emissions and has been proven to save up to four percent of fuel costs per year.

Both sensors are installed in Servomex’s custom-designed heated sensor head, which has low-flow extractive design that attaches directly to the flue. Manufactured to the highest quality standards, this ensures exceptional performance in the toughest environments and with the minimum of maintenance.

The FluegasExact’s exceptional measurement sensor capability is augmented by Servomex’s advanced Flowcube flow sensor technology. Delivering an industry first by enabling true system diagnostics of the sample flow, Flowcube gives total assurance that the measurement is valid and responding within specification. Placed in-line with the measurement sensors, Flowcube allows user-defined alarm levels to be set with confidence, either to enhance preventative maintenance or to act as a flow failure alarm output.

Flowcube technology therefore enables operators to implement a preventative rather than reactive agenda for analyser flow control, avoiding costly plant downtime by allowing the scheduling of routine safety checks and sample system maintenance – a particularly useful function where operations are being run with minimum personnel on-site.

In addition, a new Sulphur Resistant combustibles sensor enables the thick film sensor to operate at elevated levels of high sulphur where excess levels of SO2 can inhibit traditional catalytic sensor function.

Customer-designed for high temperature processes up to 1750°C (3182°F), the FluegasExact is ideal for use in extreme heated environments. This resilience makes it the analyser of choice for controlling a wide range of combustion processes, including use in process heaters, utility boilers, thermal crackers, incinerators and furnaces.
