TecArtrc desuperheater enable very precise regulation of injection water amounts for the hot steam cooling. The special nozzle design and individual actuation uses a 90° rotary movement and ensures constant microfine atomisation of the injection water. The shut-off is performed with TECtemp HD by using an integrated ball / seat ring system outside the high thermally loaded zone. High differential pressures between injection water and process steam of, e.g. 100 bar are realized using multi-stage pressure reduction. The use of coating materials with a high resistance to wear is increasing the life cycles significantly.
