OXT1PA, OXT1PB, OXT1PC inline zirconia analyzer

OXT1000 series power plant direct insertion zirconia analyzer

1、 Overview

The OXT1000 series power plant direct insertion zirconia analyzer is based on the oxygen ion conductivity characteristics of zirconia sensors at high temperatures. By measuring the potential difference generated by the difference in oxygen concentration, it achieves accurate calculation of oxygen concentration. The analyzer adopts a split flange installation design, which can be directly inserted into the flue or pipeline to monitor the oxygen content in the flue gas in real time. It has significant advantages of fast response speed and accurate measurement.

The analyzer uses a stainless steel 304 protective tube to output monitoring data through current signals. By real-time monitoring of the oxygen content in flue gas, users can effectively adjust the air-fuel ratio, improve combustion efficiency, and reduce fuel consumption. At the same time, the device assists enterprises in monitoring flue gas emissions, ensuring that emissions comply with environmental standards and reducing pollutant emissions.

In terms of production optimization, the real-time data provided by the analyzer helps enterprises optimize process parameters, improve production efficiency and product quality. In addition, with the help of changes in oxygen content, the device can also diagnose faults in the combustion system, such as detecting air leaks, blockages, and other issues.
