AI Technical Summary

Technical Problem

Existing SCV burners have high nitrogen oxide emissions, and common nitrogen reduction methods such as flue gas external circulation lead to condensate generation and reduced boiler thermal efficiency, increasing power consumption.

Method used

Design an ultra-low nitrogen semi-premixed SCV burner, which controls combustion temperature and excess oxygen through a three-layer gas pipe structure. It adopts a layered gas intake with a central gas pipe, a middle gas pipe and an outer gas pipe, and mixes with the central air duct and the main combustion air duct. The nozzle can adjust the injection angle to avoid local high temperature.

Benefits of technology

It achieves ultra-low nitrogen emissions, avoids condensate generation, reduces burner power consumption, and ensures more uniform combustion, making it energy-saving and environmentally friendly.
