| Abstract: | On the basis of reviewing the unsatisfactory aspects of currently applied pulverized coal combustion technologies, a new concept of movable heat insulate layer on furnace waterwall is put forward to improve the adaptability of boiler to coal rank and load variation. The structure and working theorem for the movable heat insulate layer is introduced and its feasibility is discussed with facts of heat transfer and experiments in laboratory and boiler. The research proves that the movable heat insulate layer is feasible and it can be applied to pulverized coal fired boiler with large scale by necessary cooling and anti slugging measures. |
