Abstract

Abstract

In order to study the influence of design deviation of thermal parameters (average temperature of primary side, feed water temperature, load and steam pressure) on the steady-state characteristics of once-through steam generator (OTSG) under rated conditions, the thermal-hydraulic experiment of typical cells for prototype design of OTSG is carried out. The experimental conditions are as follows: the average temperature of primary side is 297-304℃, the load is 100%FP-104%FP (full power), the steam pressure is 4.0-5.8 MPa, and the feed water temperature is 138-152℃. The experimental results show that the deviation of thermal parameters mainly affects the outlet steam temperature, heat transfer power and secondary side pressure drop of OTSG. The design deviation of the average temperature of primary side has the greatest influence on the steam temperature. The outlet steam temperature decreases with the increase of steam pressure under the condition that the design deviation of each thermal parameter occurs at the same time.
