摘要：
Once-through boilers ate sensitive to disturbance due to their smaller water volume. Hydrodynamic instability may occur in heating tubes as heat load changes frequently. The water-wall tube may break due to overheat. This paper gives the formulas bf sensitivity coefficient of flow, pressure loss and output enthalpy. On the basis of these formulas, the effect of several kinds of factors oil sensitivity of 600MW supercritical once-through boiler is studied. The formulas can be used for sensitivity analysis of water-wall tube in once-through boiler.
