AI Technical Summary

Technical Problem

In existing micro-oil ignition combustion systems, it is impossible to accurately control the pulverized coal concentration and inlet air volume in the secondary combustion chamber, resulting in incomplete combustion. Furthermore, it is impossible to accurately determine the injection time, leading to fuel waste and low combustion efficiency.

Method used

The system employs a combustion medium detection module and an operation process detection module to monitor pulverized coal and fuel oil parameters in real time. The operation analysis module calculates the ideal inlet air volume, pulverized coal concentration, and fuel injection time. The operation control module adjusts the actions of the air supply device, fuel sprayer, and ignition device to achieve intelligent monitoring.

Benefits of technology

It improves combustion efficiency, reduces fuel consumption, ensures the stability and safety of the combustion process, and reduces pollutant emissions.
