Hainan Dingyan Production Online Exhaust Gas Oxygen Content Analysis, Detection and Monitoring System with 13 Years of R&D Experience

1、 Application background:
During the combustion process in the furnace, when the excess air coefficient is too small, that is, when the oxygen content is insufficient, the thermal efficiency decreases and black smoke is emitted due to an increase in unburned losses; When the oxygen content is too high, and due to the large exhaust loss, the amount of SO2 and NOX increases, it will also lead to low thermal efficiency and environmental pollution. Therefore, only by utilizing the characteristics of this series of oxygen analyzers that can automatically monitor the oxygen content in various furnace flue gases continuously, can we control and optimize the air/fuel ratio, achieve economic combustion, obtain thermal efficiency, and reduce environmental pollution. The AO-100P oxygen analyzer not only provides useful parameters for operators to adjust the air/fuel ratio, but also realizes the automation of thermal control, achieving the goal of energy conservation and production increase.
