摘要：
The paper develops a down-coma feed style (DFS) of drum feed water distribution of natural circulation boiler based on the study of working process in the drum, which can greatly release the drum metal thermal stress by balancing the temperature held of drum wall. The characteristics of the DFS comparing to the normally used pressure distribution mode at present are discussed in detail. The papa analyzes the hydraulic characteristics after the down-comer feed style is adopted It is concluded that DFS is safe on circulation and simple in design, and can be widely used in subcritical pressure natural circulation boilers.
