| Abstract: | With tracing back on historical development of once-through boilers in China,the experimental study on water wall system in supercritical pressure boiler in test rig of Shanghai Power Equipment Research Institute(SPERI) has been illustrated.It addressed the required and reasonable feature for water wall of supercritical pressure boilers.The hydrodynamic performance of vertical coil and spirally wound water wall patterns have been calculated and compared respectively.Some suggestion for proper design is also made. |
