Mathematical Model and Simulation of Internal Ribbed Tube Waterwall in Ultra-supercritical Once-through Boilers

超超临界直流锅炉内螺纹管水冷壁的数学建模和仿真

In the light of the commonly encountered water wall tube explosion leakage of home made modified UP boilers an analysis is made of the thermal sensitivity of Φ 22 × 5 5 mm four head internally ribbed tubes commonly used in UP boilers.

针对国产改进型UP锅炉水冷壁经常爆漏的实际情况，分析了在UP锅炉中广泛使用的Φ22×5.5mm四头内螺纹管的热敏感性。

Under the conditions of full-circumferential heating and half-circumferential heating, the heat transfer and pressure drop characteristics of internally ribbed tube with the diameter of φ 28 × 6 mm used in the furnace water wall of 600 MW supercritical sliding pressure operation once-through boiler was studied experimentally.

本文在全周加热和单侧加热的条件下，对600MW超临界变压运行直流锅炉水冷壁φ28×6mm内螺纹管进行了传热与阻力特性的试验研究。
