BVT-DP2 probe-style desuperheater
The BVT-DP2 probe-style desuperheater is a combination of injection nozzle and water control valve, designed for precise and economical control of steam temperature. Water enters through the flanged water connection, and is passed through the desuperheater body installed in the steam pipe at an 45° angle. The nozzle at the end of the desuperheater is equipped with individual feed holes. Water enters the chamber behind the orifice plate through these openings where it is rotated before being injected into the steam flow. This rotational flow as well as the cone shaped mist the nozzle creates at the injection point reduces evaporation time, and thus improves desuperheating.
Water injection is controlled by a diaphragm actuator based on measured downstream temperature.
- Injection nozzle with rotational injection
- High rangeability and cooling efficiency
- Few moving parts and hard-faced control plug and injection nozzle resulting in high reliability and resistance against wear
- Simple installation
