Analysis of the application principle of the oxygen analyzer OMD-150 in industrial furnaces
Thread Content
Oxygen analyzer alarms are widely used in industries such as petroleum, chemicals, and pharmaceuticals. In fact, oxygen analyzers can also be used in related processes of industrial furnaces. Furthermore, under normal circumstances, explosion-proof oxygen analyzers are typically used in the workplace. The principle behind the oxygen analyzers commonly used in industry is the electrochemical oxygen sensor; they are small in size, light in weight, easy to operate, and convenient to maintain. These instruments feature membrane touch switches, offering good sealing performance as well as high accuracy and reliability. Oxygen alarms consist of two parts: a gas alarm controller and an oxygen sensor. The oxygen alarm is installed at the site to be monitored, continuously checking the oxygen concentration in the air and sending signals to the gas alarm controller to display the real-time data on site. When hypoxia or hyperoxia occurs, the instrument will immediately issue an alarm to alert the on-site staff to take action. The significance of using oxygen analyzers in industrial furnaces to measure the oxygen content in flue gases lies in preventing excessive air from entering the furnace and thereby reducing physical heat losses, as well as avoiding heat losses due to incomplete chemical combustion resulting from insufficient oxygen levels. When the oxygen content in the flue gas is low, it means that insufficient oxygen leads to incomplete combustion of the gases, and large amounts of carbon monoxide are released from the furnace, thereby contaminating the environment. When the oxygen content in the flue gas is high, it indicates an excessive excess air coefficient; as a result, the volume of flue gas increases, carrying a large amount of thermal energy out of the furnace and leading to waste. Finally, Gongcaiwang would like to briefly mention the precautions for using oxygen analyzers: First, when the oxygen content in the sample gas is too high, the inlet and outlet valves of the instrument should be shut off immediately ； Second, if the instrument is not used for an extended period of time, high-purity argon should be introduced as a protective gas, but the pressure of this protective gas should not exceed 10 KPa; otherwise, excessive back pressure can damage the diaphragm of the primary battery. Gongcai.com acts as an agent for Southland’s OMD-150 oxygen analyzer from the United States. This analyzer can be configured to detect either trace amounts of oxygen or higher concentrations of oxygen, depending on the specific application requirements, thereby meeting the needs of most industrial applications involving the analysis of trace and normal levels of oxygen. The Southland PPM-grade oxygen sensor TO2-1X from the United States utilizes micro fuel cell sensor technology, offering features such as high precision and long service life; it is widely used in various applications for measuring oxygen levels, including air separation units, chemical & petrochemical processes, and steel manufacturing.
