Precision oxygen measurement, steadfast support: Tianfen Instruments' advanced zirconia analyzers solve monitoring challenges in the hazardous waste incineration industry.

——Anhui Tianfen Instruments Helps Weihai City Solid Waste Disposal Center Achieve Efficient and Stable Operations

Introduction

In today’s world, where environmental regulations are becoming increasingly stringent, the harmless and resource-efficient disposal of hazardous waste has become a critical component of urban development. As the mainstream technology for treating hazardous waste, incineration relies heavily on the precise control of the high-temperature combustion process within the incinerator. Flue gas oxygen content As a critical parameter for measuring combustion efficiency and controlling pollutant emissions (such as dioxins and NOx), the accuracy and stability of its monitoring directly determine the operational effectiveness of the entire disposal system and its ability to meet environmental standards.

However, the extremely harsh operating conditions of hazardous waste incineration—characterized by complex compositions, strong corrosiveness, and high dust concentrations—pose a severe challenge to conventional oxygen analyzers. Sensor probes are prone to corrosion, have a short lifespan, and suffer significant measurement drift, making this a long-standing "critical issue" that continuously plagues operational units.

Customer pain point: When precision instruments encounter extreme operating conditions

Shanghai ChengTou's Weihai Solid Waste Disposal Center shoulders the critical responsibility of safely managing hazardous waste in Weihai City and surrounding areas. At the heart of its operations is a hazardous waste incinerator, which has been continuously seeking a long-term, stable, precise, and reliable oxygen-monitoring solution to ensure optimal performance during operation.

Previously, the center has been plagued by the short lifespan of its zirconia oxygen analyzers. The flue gases produced from hazardous waste incineration often contain highly corrosive components such as halogens, sulfides, and heavy metals, which rapidly erode the sensitive electrodes of the sensor probes, leading to:

Probe rapidly aging : Measuring signal attenuation requires frequent calibration.

Loss of precision : The measurement is inaccurate, failing to provide the combustion control system with correct feedback.

Frequent replacement High costs of spare parts and prolonged downtime for maintenance severely impact production efficiency and economic profitability.

They urgently need a zirconia oxygen analyzer that is "durable, accurate, and long-lasting."

Solution: Tianfen Instrument's "Hardcore" Technology

Facing this common challenge across the industry, Anhui Tianfen Instrument Co., Ltd. leverages its deep-rooted technological expertise in the high-end zirconia oxygen analysis field to deliver its flagship product— An oxygen analyzer system featuring the original "ion-plating and platinum-sphere corrosion-resistant coating technology" made with zirconia. 。

The core advantage of this solution directly addresses the customer's pain points:

1. Pioneering ion plating technology: Building a dense protective shield
The Tianfen Instrument abandons traditional spraying or coating processes, instead employing advanced ion-plating technology to form an ultra-thin, dense, and exceptionally strong-bonded protective film of precious metals on the surface of the core component in the zirconia oxygen sensor. This film effectively prevents corrosive substances in the flue gas from directly contacting the internal electrode materials, significantly enhancing the probe's durability at a fundamental physical level. Corrosion-resistant And Anti-erosion Ability.

2. Platinum Sphere Corrosion-Resistant Coating Technology: Double Protection, Solid as a Rock
At the critical electrode terminals, Tianfen Instruments has innovatively applied "platinum-sphere corrosion-resistant coating technology." This technology creates a specialized precious-metal alloy coating on the electrode surface, resulting in a more stable structure and enhanced chemical inertness—effectively equipping the precision sensor with a tailor-made "protective armor." Even under extreme conditions of high temperature and intense corrosion, it ensures both the electrode reaction's activity and long-term stability, fundamentally slowing down the sensor's performance degradation.

Application Impact: From "Satisfaction" to "Trust" Transformation

Since Weihai City Solid Waste Disposal Center adopted the zirconia oxygen analyzers from Anhui Tianfen Instruments, the operational monitoring of its incinerators has been fundamentally improved:

Lifespan significantly extended Under the same harsh operating conditions, Tianfen Instruments' zirconia sensors have a longer service life compared to the previously used brand products. Increased several times , significantly reducing customers' frequency of purchasing spare parts and lowering inventory costs.

Measurement remains consistent and stable. :The instrument output signal is stable and reliable, with measurement accuracy consistently maintained within the optimal range. This provides precise data support for the incinerator's automatic control system, helping to optimize furnace temperature control and air-to-fuel ratio adjustments.

Maintenance costs significantly reduced : Thanks to the sensor damage being virtually eliminated, unplanned downtime has been reduced to almost zero, allowing for extended calibration cycles and significantly saving customers on labor-intensive maintenance costs as well as lost production time.

Environmental standards are more reliably met. Stable oxygen content measurements ensure complete combustion, effectively suppressing the formation of harmful substances like dioxins at the source—and providing customers with robust data to meet environmental emission standards.

The technical leader from the customer side highly praised the product, saying: "Tianfen Instruments' product has truly addressed one of our long-standing concerns. Not only does it deliver outstanding performance, but more importantly, its remarkable durability gives us peace of mind even under the challenging conditions of hazardous waste incineration. This was an exceptionally successful equipment selection, and we deeply appreciate Tianfen Instruments' technological expertise and innovative strength."

Conclusion

The successful application of Weihai City's Solid Waste Disposal Center perfectly exemplifies Anhui Tianfen Instrument Co., Ltd.'s philosophy of "solving customers' real-world challenges through technological innovation." As the environmental protection industry advances into a new era of refined and highly efficient operations, reliable monitoring equipment serves as the "sensing organs" and "decision-making brains" that ensure its stable performance. Anhui Tianfen Instrument will continue to deepen its expertise in the high-end gas analysis field, delivering even more exceptional products and technologies to contribute Tianfen's unique strength to China's environmental protection efforts as well as industrial energy conservation and emission reduction initiatives.
