Abstract: An introduction is being presented to development history and status of hydrodynamic perfor-
mance study for domestic power plants, including the early stage power plant boiler, sub-critical once-
through boiler, natural circulation boiler and supercritical forced-flow once-through boiler, while the d
velopment tendency and emphases forecast. High-parameter high-capacity power equipment will be devel
oped; steam arameters of next generation of ultra supercritical boiler will reach 700 C, 35 Mpa. All
these require deep research on relevant boilers hydrodynamic performance. For boilers with different com-
bustion modes licensed by domestic 3 big power equipment manufacturing groups, corresponding hydrody-
namic study is also necessitated, so as to guarantee safety operation of the boiler. To the standard JB/Z
201-1983"Hydrodynamic Calculation of Power Plant Boilers", new technologies and research achieve
ments have to be added, due to the limitation of publication time.
Key words hydrodynamic performance and heat transfer of power plant boiler; mixer; distribution head
er; overpressure; hydrodynamic adjustment; hydrodynamic study; supercritical pressure
