From zirconia probes to oxygen sensors, these have been widely used in many industries at home and abroad, and have achieved a certain degree of economic benefits. Today, let's briefly talk about how zirconia probes and oxygen sensors are used in the power generation and kiln industries. Let's find out together.

　　Brief description of the application of zirconia oxygen probes in kiln combustion

　　In kilns, achieving economical combustion, i.e., controlling the air-fuel ratio, not only saves energy but also reduces air pollution. Economical combustion is achieved through a closed-loop control process that automatically adjusts the air intake based on the oxygen content in the flue gas as the main signal; therefore, the zirconia oxygen probe is a key instrument for achieving economical combustion.

　　Nowadays, there are nearly 300,000 kilns in China, and most of them use coal as fuel. Coal has a high sulfur content, and the flue gas contains dust, sulfur, and water vapor. To reduce these problems, Tianfen Instrument's R&D personnel have made many efforts in the field of automatic control systems.

　　The new zirconia probe combustion efficiency online analysis probe uses semiconductor ceramic gas sensor technology and a dual-probe structure suitable for harsh environments. Through continuous online detection of various kiln flue gases and protective gases, it achieves the goal of controlling the combustion air-fuel ratio and monitoring the purity and leakage of protective gases, ensuring product quality and meeting emission standards.

　　Brief description of the application of zirconia oxygen measuring devices in thermal power plants

　　Thermal power plants are major coal consumers, accounting for more than 20% of the country's annual coal production. Reducing coal consumption and saving energy are urgent tasks. As a monitoring instrument for boiler combustion in power plants, the zirconia oxygen analyzer plays an important role in guiding combustion.

　　Currently, the most recognized and cost-effective method for measuring flue gas oxygen content is zirconia. Tianfen Instrument's high-temperature integrated zirconia oxygen analyzer, composed of an oxygen probe and an oxygen transmitter, can be directly installed at different locations in the furnace tail flue for real-time monitoring. With a high-temperature adapter, the high-temperature flue gas is introduced into the adapter, expanded, decompressed, and cooled to reduce its actual temperature to below 600℃, thereby achieving detection of high-temperature gases. The advanced technical ceramic probe protector is corrosion-resistant and high-temperature resistant, capable of withstanding temperatures as high as 1400℃. With reliable quality and accurate and stable measurement data, it is now widely used in combustion monitoring and control processes in various industries, and has successfully helped the lighting industry achieve considerable energy-saving effects.

　　As a substance in solid electrolytes, the zirconia oxygen sensor has evolved from a single component to a mixed application in numerous fields today, reflecting our continuous exploration and breakthroughs in science and technology, turning the impossible into the possible!
