AI Technical Summary
In existing SNCR denitrification systems for coal-fired boilers, the fixed angle of the spray gun cannot adapt to changes in the temperature field inside the furnace, resulting in inaccurate reductant injection, which affects denitrification efficiency and ammonia escape control, and also leads to low maintenance efficiency.
The system employs an elastic connection structure between the spray gun barrel and the positioning sleeve, combined with a servo motor and linkage mechanism, to achieve adaptive adjustment of the spray angle. The system also utilizes the cooperation of springs and balls to achieve multi-angle dynamic adjustment of the spray gun, simplifying the installation and disassembly process.
It improves the dynamic adaptability of the injection angle, enhances denitrification efficiency and ammonia slip control, simplifies the maintenance process, and improves work efficiency.
