Overview
Advanced Flue Gas Analyzer for Oxygen and Combustibles
Equipped with a specialized integral sampling system tailored for operation in some of the hottest and most extreme combustion environments, the SERVOTOUGH FluegasExact 2700 accurately measures oxygen and combustibles in the most challenging hydrocarbon processing and power generation applications.
Engineered for high-temperature processes reaching up to 1750 °C (3182 °F), it is perfectly suited for extremely hot environments. This durability establishes it as the preferred analyzer for managing a diverse array of combustion processes, including applications in process heaters, utility boilers, thermal crackers, incinerators, and furnaces.
Unbeatable Performance in the Most Challenging Locations
In combustion analysis applications where high temperatures and particulates or dust pose occupational hazards, it is essential to have a gas analysis solution that provides exceptional durability and unmatched performance. The SERVOTOUGH FluegasExact, featuring a durable, fully heated stainless steel device, is certified for Zone 2/Division 2 monitoring. Options for high-temperature and flow sensors also enhance operational capabilities.
A No-Compromise Solution
At the core of the SERVOTOUGH FluegasExact’s outstanding performance lies Servomex’s Zirconium Oxide cell, which is utilized for oxygen measurement, alongside a thick-film catalytic sensor designed for the measurement of carbon monoxide and COe (combustibles). The integration of these two technologies enhances process control and aids in optimizing excess oxygen, thereby reducing SOx, SO3, and CO emissions, with evidence suggesting a potential annual saving of up to 4 % in fuel costs. Both sensors are housed within Servomex’s specially designed heated sensor head, featuring a low-flow extractive design that allows for direct attachment to the flue or remote mounting. Manufactured to meet the highest quality standards, this design guarantees exceptional performance even in the most challenging environments while requiring minimal maintenance.
Unbeatable Value Over Product Life
The capacity to lower continuous maintenance expenses and decrease long-term ownership costs is crucial, while operational advantages such as straightforward installation requirements are particularly appealing. Backed by Servomex’s worldwide service network, which provides comprehensive support from commissioning to servicing, the FluegasExact ensures outstanding performance and a prolonged lifespan.
