AI Technical Summary

Technical Problem

Existing technologies for controlling coke oven exhaust gas combustion cannot dynamically adapt to changes in exhaust gas composition, leading to unstable combustion, excessive CO emissions, or energy waste. Furthermore, a single control target may trigger pollution transfer.

Method used

An exhaust gas reprocessing and combustion control system based on emission monitoring is adopted. Through multi-source sensor detection, feedforward process control, feedback process control, reprocessing execution and monitoring and early warning modules, the system monitors intake and exhaust data in real time, establishes a real-time concentration-flow model of nitrogen oxides and carbon monoxide, generates multi-level adjustment commands, and coordinates the flow of reprocessing exhaust gas and combustion air.

Benefits of technology

It achieves synergistic emission reduction of nitrogen oxides and carbon monoxide, ensures combustion efficiency, reduces greenhouse gas emissions, optimizes energy utilization, and avoids incomplete combustion and energy waste.
