中文摘要	The hydrodynamics of the water wall in a 600 MW circulating fluidized bed (CFB) boiler was studied, and water cooled panels were deposited in the furnace. The mass flow rate and the temperature distribution of the water wall with throttles within the smooth tubes was discussed. It was found that the outlet temperature of water wall is less than 422 degrees C, when the mass flow rate is below 1000 kg/(m/sup 2/ ldr s) at the load of 100% boiler maximum continuous rating (B-MCR). And heat difference can be controlled within 2%. At the load of 75% turbine heat acceptance (THA) or 50%THA, the wall temperature is also not too high to be allowed. Compared with the ribbed-tube, the usage of them can reduce the water wall temperature but no good to the heat deviation. Smooth tube with throttle is better than ribbed tube in the 600 MW supercritical CFB boiler.
