Carraro - Desuperheater VariSpray
VariSpray is a desuperheater with fixed-area nozzles and is used for injecting water droplets into steam via a venturi-shaped section. Along with a combination with a pattern of nozzles, this ensures an excellent and rapid atomization of the injected water
Particularly suitable for low speed vapors so that steam can be thoroughly treated and with a minimum temperature difference of 6 ° C over saturation.
They are primarily intended for low-capacity processes with moderate load changes and where accurate temperature control is important
Primary applications:
- Turbine Sealing
- Steam cooling
- Heat exchangers
- ejectors
- Additives for tire vulcanization
- General purpose such as boilers
