Summary:The utility model belongs to a slag-discharge pipe of a circulating fluidized bed boiler, particularly relates to a water-vapor sealed slag-discharge pipe of a circulating fluidized bed boiler, and solves the problems as follows: in the prior art, the slag-discharge pipe of the circulating fluidized bed boiler is easily coked and plugged and the slag is hard to remove. The water-vapor sealed slag-discharge pipe of the circulating fluidized bed boiler includes a slag-discharge pipe body, a slag-discharge plugboard door is arranged at the bottom of the slag-discharge pipe body, an air inlet pipeconnected with water vapor source and communicated with the slag-discharge pipe body is arranged on the slag-discharge pipe body, and a control valve is arranged on an air inlet pipe. The utility model has the benefits as follows: water vapor is used to seal the slag-discharge pipe, so that the air can not enter the inside of the slag-discharge pipe; the temperature is reduced, so that the interior coking of the slag-dis
