This peper describe the vertical riser tube coils waterwall of a 600 MW supercritical boiler
its hydrodynamics
heat transfer
operation performance in start-up and low load process.Merits and demerits of the use of vertical tube coils on a 600 MW supercritical once-through boiler are summarized.The conclusions of this peper are of important reference to supercritical utility boiler waterwall designs.
