Thermal power unit and its denitration control method and system based on NH3 measurement |
| abstract |
The invention discloses a denitration control method based on NH 3 measurement, comprising: acquiring NH 3 measurement values of several measuring points in a flue; controlling the ammonia injection amount in the corresponding area of the flue according to the NH 3 measurement values; The PID feedforward value is calculated by the broken line function; the NOx concentration at the denitration outlet is controlled according to the PID feedforward value. The invention also discloses a denitration control system based on NH 3 measurement and a thermal power unit including the above-mentioned denitration control system based on NH 3 measurement. The above-mentioned denitration control method based on NH 3 measurement can provide a basis for operators to adjust the opening of the ammonia injection valve through the monitoring of NH 3 parameters at multiple measuring points, making the amount of ammonia injection in each area more reasonable, and effectively preventing NH 3 overspray At the same time, by introducing the PID feedforward value into the denitration control system, the control reliability of the denitration control system can be effectively improved, and the environmental protection reliability can be improved. |
