| Abstract: | The water wall system can be equivalent to a network consisting of circuits,pressure grids,and connecting pipes.A mathematical model for calculating pressure drop and outlet steam temperature of a supercritical once-through boiler was established on the basis of the mass conservation,momentum conservation and energy conservation equations.Moreover,the pressure drop in the up-system and the outlet steam temperature of a 600 MW supercritical once-through boiler with spiral tube coils at Ligang Power Plant wer... |
