Combustion optimization system and method thereof

Abstract

A combustion optimization system is disclosed. The system comprises a boiler having a plurality of subarea positions, a sensor grid including a plurality of sensors, a sensor verification device and an optimizing controller. The plurality of sensors are used to provide a plurality of sensor signals used for expressing measurement values of the respective subarea positions. The sensor verification device is used for receiving the plurality of sensor signals from the plurality of sensors and generating verified sensor signals of the respective sensors based on the plurality of received sensor signals and a pre-determined correlation among the plurality of received sensor signals. The optimizing controller is used for optimizing at least one operating parameter of the boiler based on the verified sensor signals of the respective sensors. A combustion optimization method is also disclosed.

Description

technical field [0001] The present invention generally relates to the control field, and in particular relates to a combustion optimization system and a combustion optimization method. Background technique [0002] Sensors are commonly used to measure and collect various data related to important operating parameters of the system, such as temperature, pressure, gas concentration, etc. The output signal of the sensor changes based on changing conditions in the system. Therefore, a typical application of sensors is to monitor the performance of the system, so that the performance of the system can be effectively controlled. Signals from sensors can be used for evaluation. Based on the results of the evaluation, one or more operating parameters of the system will be changed or controlled to improve the efficiency of the system. The more accurate the sensor signal is, the better the control of the system is, so the accuracy of the sensor signal plays a vital role in the cont...

AI Technical Summary

Problems solved by technology

However, over time, the harsh environment in the boiler system will inevitably cause the sensor to age, degrade and fail.

Therefore, the signals from these low performance sensors will not accurately reflect the data of the boiler system and may also cause inappropriate combustion control

This improper combustion control can result in lower combustion rates, higher NOx and CO concentrations, and reduced reliability

Furthermore, this improper combustion control may also lead to increased slag build-up and increased boiler tube failure, and even catastrophic consequences such as furnace fire extinguishment or explosion
