Domestic high-end zirconia oxygen analyzer achieves import substitution, Tianfen Instruments promotes technological upgrading in the energy industry

Recently, the zirconia oxygen analyzer independently developed by Anhui Tianfen Instrument Co., Ltd. has been successfully applied in a coal-fired boiler project of a power plant under the National Energy Group, replacing the same type of equipment from the original imported brand ABB. With its excellent pressure resistance, high precision, and stability, the equipment performs excellently under harsh working conditions, receiving high recognition from users, marking a significant technological breakthrough in China's high-end industrial analytical instruments in the coal-fired power generation field.

Innovative technology breaks the import monopoly
The zirconia oxygen analyzer used this time adopts the wear-resistant ceramic sheath technology specially designed by Tianfen Instruments, solving the industry pain point that traditional zirconia oxygen probes are easily worn and have a short lifespan in high-temperature, high-pressure, and high-dust environments. Compared with imported equipment, its wear resistance is improved by 30%, the measurement accuracy reaches the industry-leading level of ±0.5%, and the operational stability is significantly enhanced, greatly reducing the equipment maintenance frequency and downtime risk. The technical director of the power plant said: "After the equipment was put into operation, the boiler combustion efficiency optimization effect is obvious, the data feedback is real-time and accurate, and it fully meets the stringent requirements of ultra-low emission transformation."

Full-scenario coverage replaces imported zirconia oxygen analyzers
After years of technological research and development, Anhui Tianfen Instruments has now formed a complete product matrix of high-end zirconia oxygen analyzers, which can perfectly replace ABB, Rosemount, Ametek, GE, Siemens, Zillox, Novatek, Yokogawa Japan, Fuji Japan, Norfatek, Shifumei, and Watson Canada and more than ten international brands of zirconia oxygen analyzers. Its core technological advantages include:

Intelligent operation and maintenance system ：Integrates automatic calibration and automatic purging functions to reduce manual intervention;

Extreme working condition adaptability ：Special alloy probe and multi-layer protective structure, realizing triple protection against corrosion, vibration, and scouring;

Multi-scenario solutions ：For complex process scenarios such as garbage incineration, hazardous waste treatment, and acid production, the sensors are enhanced with sulfur-resistant coatings, platinum coatings, and imported CPUs to optimize program algorithms, improving service life and reducing measurement errors.

Environmental protection industry welcomes domestication opportunities
Driven by the "dual carbon" goals, Tianfen Instruments' innovative products have been implemented in many domestic benchmark environmental protection projects. Comparative tests at a garbage incineration power plant show that its equipment reduces data volatility by 60% in oxygen content monitoring in key links of dioxin control, helping customers pass EU emission standard certification. The general manager of the company said: "We are accelerating the layout of sensor research and development in emerging fields such as hydrogen energy and carbon capture, with the goal of achieving independent and controllable industrial analytical instrument full industrial chains within three years."

Currently, Anhui Tianfen Instruments has established strategic cooperation with the five major power generation groups, many large chemical enterprises, and metallurgical and steel enterprises, with the proportion of domestic substitution projects exceeding 70%. With the transformation and upgrading of China's high-end manufacturing industry, the performance advantages and cost competitiveness of domestic analytical instruments will be further released, injecting new impetus into the high-quality development of the energy and environmental protection industry.
