The results of study on waterwall's hydrodynamics of 600MW supercritical Unit's primary riser tube coils are presented. The corresponding application program is developed. Calculations of flow distribution, outlet steamtemperature deviation and temperature at waterwall, etc. under diverse ways of throttle and different load rates are conducted by using this program and thermal load distribution. On this base, the feasibility of applying vertical tube coils to 600MW supercritical sliding pressure once-through boiler is demonstrated. Figs 12,tables 3 and refs 8.
