Abstract: The research on double-reheat boilers with the reheat steam temperature high up to 630℃ is being carried out in China. To resolve the difficulties in the development of the boilers, a series of key technologies have been studied and corresponding solutions are proposed, such as the boiler general layout optimization, application of new materials, reheat steam temperature adjustment, wall temperature deviation control, upgrade of the water wall design and manufacturing techniques, and so on. The results show that the requirement of 630℃ parameter can be achieved effectively by adopting the technology of front and rear wall burning off combustion, π type layout and temperature control with three flue baffles.
