Cross sectional viewThis desuperheater ensures a fine conical spray, that evaporates almost instantaneously avoiding pipe impingement and eliminates the need of separate coolant valve.
Reliability is at its maximum owing to hard faced trim and single moving part. It utilises full pressure drop at all conditions thereby maintaining its characteristic even at low loads. Turndown ratios of 40 : 1 are offered as standard. Units are available with modified, parabolic, equal and linear characteristics as per requirements. |
