| Abstract: | Ways to study the hydrodynamic and heat-transfer characteristics of water wall tubes in a power plant boiler are being discussed, using a segment of electric heating tube and real radiant water wall tubes, to which a comparison and analysis have been carried out. Experimental results are finally given, concerning the hydrodynamic and heat-transfer characteristics of the spiral water wall tubes in a 1 000 MW ultra supercritical-pressure tower-type once-through boiler, respectively tested in a real furnace and a hydrodynamic test rig. This may serve as a reference for design of water wall systems for similar power plant boilers. |
