proven technology
Zirconium Oxide technology has been used for over 50 years in combustion processes. Though the science is settled, packaging concepts have evolved overtime. Zirtek Analyzers has built on fundamentals that initially endured in the high temperature, harsh atmosphere of the glass industry. The changes have been small, but important, to successful application in incinerators, kilns, thermal oxidizers, coking units, as well as
recovery units for both sulfur and bromine. Once you have prepared to do the "dirties", boilers, heaters and furnaces are easy.
The Zirtek Analyzers' approach is to keep it simple so it will survive longer with little or no attention. The in-situ design, heating the cell with the process gas, and sensing cell voltage, not current, eliminates the need for heaters, filters, aspirators, calibration, etc. Site preparation can be as simple as a mounting fitting, a small flow of metered reference air and a four conductor signal cable.

advanced design
The ZKA Series Analyzer is the third generation since Zirtek Analyzers entered the market in 1989. The heart of the analyzer is a proprietary board designed and man-ufactured here in the USA using cutting edge technology. The design combines
the stability of analog signals, for control, with the flexibility of serial communications to provide the user with installation variations that fit site requirements. The analyzer electronics can be nearby the probe or a 1000+ feet away, connected by a standard 4 conductor (twisted pair, copper-copper) with an overall shield, instrument cable.
The Display Module (DM) is a graphic HMI featuring a touchscreen, serial com-munications, IP address, trending,histor-ical data logging and remote operation via VNC. One DM can function as the interface to multiple probes. Each probe has a dedicated control board that is linked to the DM via an RS422 daisy chain.

Cost effective combustion control begins with oxygen measurement. Fast, reliable feedback of the actual excess oxygen concentration to trim an air/fuel ratio control loop can ensure safe, stable operation while keeping the fired process in its sweet spot. Why install more expensive, higher maintenance devices for control based on carbon monoxide (CO) when CO can already be accounted for as a combustible in the oxygen measurement?
Whether your priority is lower fuel cost or lower emis-sions, you can achieve both with increased efficiency resulting from measuring excess oxygen in the radiant section of the fired process.
~ Less fuel means less cost.
~ Less fuel means less CO2 released
~ Less excess oxygen means less NOx formed
Is your fired process sub-stoichiometric?
