Research on the Hydrodynamic Characteristics and Metal Temperature Distribution in Spiral tube Water Wall of an Ultra Supercritical Boiler

摘要：

On the basis of a 350MW supercritical pressure OTSC boiler, established the mathematical model for the circulation loop flow and grid pressure in a complex flow network system, and an iteration method was used to solve the nonlinear equations. The water wall flow distribution and temperature profile of the boiler were computed. The results show that the flow difference and heat difference are small in spiral tube water wall at BMCR, 75％BMCR load and 30％BMCR load. The metal temperatures are all in the range of allowable range, and the operation of boil is safe and reliable.
