Recently, the Nernst N2001 zirconia oxygen analyzer, with its wide range measurement capability and stable performance, has been widely applied in combustion optimization projects in the fields of power, steel, and chemical engineering. It has successfully overcome the energy efficiency improvement bottleneck and environmental compliance pressure faced by enterprises, and has become an important technical support for industrial green transformation.
In the boiler renovation project of a large thermal power plant in East China, the instrument demonstrated outstanding high-temperature adaptability. Previously, due to the large temperature fluctuations in the boiler tail flue (300 ℃ -1100 ℃), traditional monitoring equipment frequently experienced data drift, resulting in delayed air-fuel ratio adjustment. This not only caused an annual coal consumption of over 3000 tons, but also resulted in nitrogen oxide emissions often approaching the limit.
By deploying the Nernst N2001 analyzer, its wide temperature measurement range from room temperature to 1200 ℃ perfectly matches the working conditions, and the real-time output of oxygen content parameters and oxygen potential data provides accurate basis for optimizing secondary air. The operation and maintenance director of the power plant said, “After the 4-20mA signal of the instrument is directly connected to the DCS system, we can dynamically adjust the air coal ratio. Currently, the boiler thermal efficiency has increased by 4.2%, and the annual emission reduction of nitrogen oxides is nearly 200 tons.”
The high-temperature smelting scene in the steel industry highlights the technological advantages of this instrument. The sintering furnace of a steel enterprise in Hebei Province has experienced frequent fluctuations in sintered ore quality and gas leakage risks due to inaccurate oxygen content control.
The Nernst N2001 analyzer has an ultra wide measurement range of 10 ⁻³ ⁸ to 100%, which not only meets the low oxygen monitoring requirements of the sintering process, but also can cope with the high oxygen environment during equipment maintenance. Its RS485 communication interface enables seamless integration with the blast furnace control system. When the oxygen content exceeds the preset threshold, the automatic alarm function can trigger ventilation control in the first time.
The qualified rate of enterprise sintered ore has been increased to 98.5%, and the gas utilization efficiency has been improved by 12%.
In the field of chemical engineering, the application case of ethylene cracking furnace in a petrochemical enterprise in Jiangsu is also typical. The company had previously experienced catalyst poisoning accidents multiple times due to delayed monitoring of oxygen content at the reactor outlet.
With the real-time monitoring and alarm function of Nernst N2001 analyzer, the operator can adjust the process parameters in advance according to the data to avoid side effects caused by peroxide or hypoxia. The high-precision measurement and fast response characteristics of the instrument have extended our catalyst replacement cycle by three months and reduced unplanned downtime losses by over one million yuan annually,” said the enterprise’s technical manager.
It is understood that the widespread application of the Nernst N2001 analyzer is driving the upgrade of industrial combustion monitoring. Its versatility in adapting to various types of equipment such as boilers and kilns, as well as its compliance guarantee capability in the context of tightened environmental standards, has become a priority choice for industries such as power and metallurgy, providing strong support for enterprises to achieve the dual goals of “energy conservation and carbon reduction” and “safety production”.
