the heat absorption rate of evaporating section on boiler of the 700 ℃ unltra-supercritical unit decreases significantly.The proportion of pure radiant heat released by gas to the water wall can not be decreased by the heat absorption rate of steam in 700 ℃ unit boiler
so the superheating ratio selection and the heating surface arrangement had large difference with that of the present 600 ℃ ultra-supercritical unit boiler.Therefore
selecting a suitable superheating ratio
arranging heating surface of evaporating system and designing new superheater or reheater system are the key projects to investigate for the 700 ℃ ultra-supercritical unit boiler.
