| ROTAMIX® - second generation SNCR |
| ROFA® prepares for the effective mixing of chemicals in the furnace. The ROTAMIX® system has been developed for optimum reduction of unwanted substances, such as NOx, SOx and heavy metals. The same kind of asymmetrically placed air nozzles are used in the ROTAMIX® technique as in the ROFA® system. |
| To optimize NOx reduction, chemicals are added. These chemicals are added using lances that are inserted in the ROFA/ROTAMIX® nozzles. The high velocity air in the ROFA system carries the chemicals into the center of the furnace. The flow of chemicals is automatically regulated by the Moboview software. The lances can be easily removed by hand for inspection, even during operation if necessary. Effective NOx reduction can be achieved with the minimum amount of ammonia slip. |
| Chemicals are injected into the boiler through the ROFA/ROTAMIX® nozzles. Ammonia or urea can be injected to reduce NOx. A smaller amount of chemicals are needed to obtain the same NOx reduction because of the mixing action provided by the high velocity air. |

| Limestone, lime, or soda ash can be injected into the boiler in the same manner to reduce SO2, and limestone or activated carbon can be injected to reduce mercury. |
