| Abstract: | Went along a theory analysis for the operation characteristics of 1 000 MW Ultra-supercritical boilers with vertical rifled tube platen water wall,especially went along the analysis for the influence of water wall thermal deviation on flow deviation,the heat transfer characteristic of rifled pipe and the flow characteristics of a strait boiler where the force-flow in the water wall is partly canceled out by natural circle when the flow rate is low. |

| Keywords: | ultra-supercritical boilers unit rifled water wall vertical tube platen low mass flow rate operation characteristics |
