AI Technical Summary

Technical Problem

The existing technology of manually adjusting the air intake cannot meet the burner's need for complete combustion in complex environments, especially in conditions such as high altitude and low temperature, where problems such as incomplete combustion, difficulty in low-temperature ignition, and excessively long flames exist.

Method used

By collecting flame images and temperature field data during burner combustion, a combustion state recognition model is constructed. A deep learning network is then used to identify the combustion state and automatically adjust the air intake to achieve constant power combustion.

Benefits of technology

It enables automatic air intake control of the burner in complex environments, improving combustion efficiency and reliability, and ensuring complete combustion of the constant power burner.

Abstract

The present application relates to the technical field of combustor, and provides a kind of combustor air intake control method and device.The method includes: collecting the flame image and temperature field data when combustor burns under different air intake conditions, normalizing and denoising the flame image with combustion state label, and combining to obtain flame image dataset;Temperature field data with combustion state label is normalized and denoised, and combined to obtain temperature field dataset;Flame image dataset and temperature field dataset are used to train and build combustion state recognition model;According to real-time flame image, real-time temperature field data and combustion state recognition model, the current combustion state of the combustor is identified, and the air intake of the combustor is controlled according to the current combustion state.The present application detects the combustion state in real time through multi-modal feature fusion, and automatically controls the air intake according to the combustion state, thereby effectively improving the combustion efficiency and realizing full combustion of constant-power combustor.
