DESUPERHEATER AND DESUPERHEATER SPRAY TUBE

摘要

PROBLEM TO BE SOLVED: To appropriately decrease the temperature of superheated steam.;SOLUTION: A desuperheater comprises: a water tube 21 at which a spray nozzle is formed; an outer cylinder 22 covering the water tube 21; and a baffle 29-1. Such a desuperheater flows warming steam to a warming steam channel 26 formed between the water tube 21 and the outer cylinder 22, and injects the warming steam and mist sprayed from the spray nozzle from a hole 27-1 formed in the outer cylinder 22 to superheated steam. The baffle 29-1 is arranged upstream of the hole 27-1 in the warming steam channel 26. Such a desuperheater can decrease offset of a direction in which the mist is injected by the warming steam by disturbing the warming steam by the baffle 29-1, spray the mist in an appropriate direction, and appropriately decrease the temperature of the steam.;COPYRIGHT: (C)2015,JPO&INPIT
