1. combustion efficiency monitoring

Optimize air-fuel ratio:

Different combustion equipment and fuel types have their corresponding optimal air-fuel ratio range.O2S-FR-T2-18CThe sensor accurately measures the oxygen content of the flue gas and provides a key basis for adjusting the air-fuel ratio. For example, in coal-fired boilers, according to the different coal quality, the oxygen content data fed back by the sensor can adjust the air supply volume to make the coal burn fully.

Energy saving and consumption reduction:

Taking industrial kilns as an example, if the oxygen content is too high, it indicates that a large amount of air is discharged without participating in the combustion, taking away a large amount of heat. According to statistics, every increase in excess air coefficient 0.1Heat loss may increase1.5%-2.0%. Using sensor data to adjust the air-fuel ratio can make the combustion closer to the ideal state and reduce fuel consumption.

Improve combustion stability:

A stable combustion process is essential for production.O2S-FR-T2-18CThe sensor monitors the oxygen content in real time, helping the operator to detect fluctuations in the combustion process in time. For example, in a gas turbine, when the load changes, the fuel supply and air volume are adjusted according to the sensor data to ensure stable combustion and prevent accidents such as flameout or deflagration.

2. Pollutant Emission Control

Accurate calculation of emission concentration:

Environmental regulations require companies to convert pollutant emission concentrations into concentrations at baseline oxygen levels.O2S-FR-T2-18CThe sensor provides accurate real-time oxygen content data, combined with other pollutant sensors to measure the concentration of sulfur dioxide, nitrogen oxides, etc., according to the relevant formula for conversion. For example, in a thermal power plant, the actual oxygen content is calculated according to the sensor data.8%The concentration of sulfur dioxide is100mg/m³The reference oxygen content can be obtained by the conversion formula.6%The concentration of sulfur dioxide emissions in order to compare with environmental standards.

Process control and early warning:

In the production process, once the oxygen content is abnormal, it may lead to an increase in the amount of pollutants. For example, in a waste incineration plant, if the combustion is insufficient and the oxygen content is reduced, more harmful substances such as carbon monoxide will be produced. The sensor monitors in real time. When the oxygen content deviates from the normal range, the system issues an early warning to remind the operator to adjust in time to reduce the generation of pollutants.

Environmental Compliance and Regulation:

Environmental Protection DepartmentCEMSSystem monitoring data as the basis for the supervision of enterprises.O2S-FR-T2-18CThe sensor ensures accurate oxygen content data, making supervision more scientific and fair. When an enterprise exceeds the standard, the environmental protection department can impose penalties and rectification requirements based on the data to prompt the enterprise to strengthen pollution control.

3. equipment running status monitoring

Diagnose burner faults:

The burner is the core component of the combustion equipment, and its working state directly affects the combustion effect. WhenO2S-FR-T2-18CWhen the oxygen content measured by the sensor is abnormal, it may be the nozzle of the burner is blocked, the gas supply is not smooth, or the air conditioning mechanism is faulty. For example, in an oil-fired boiler, if the oxygen content suddenly increases, the fuel injection nozzle may be blocked, resulting in a decrease in fuel injection volume and a relative excess of air.

Detect air duct problems:

Air duct blockage or leakage can affect air flow and distribution, which in turn affects oxygen content. Abnormal fluctuations in sensor data may indicate an air duct problem. For example, in the heating furnace of a steel plant, if the oxygen content is measured at different locations, it may be that the air duct is partially blocked or leaked, resulting in uneven air distribution.

Predict equipment failure:

By analyzing the long-term data of the oxygen sensor, the trend model of the equipment operation can be established. When the oxygen content data is continuously abnormal or the change trend deviates from the normal range, it indicates that the equipment may have potential faults. For example, in the rotary kiln of a cement plant, if the oxygen content gradually increases and there is no obvious improvement after adjusting the air-fuel ratio, it may be that the kiln body is not tightly sealed and needs to be repaired in time to avoid the expansion of the fault.
