Embodiment Construction
[0012] A method for avoiding slagging in the hearth of a circulating fluidized bed boiler in this embodiment, when applied to the hearth of a circulating fluidized bed boiler, the low-pressure saturated steam is sequentially squeezed through the wind box and the air distribution plate and introduced into the hearth of the circulating fluidized bed boiler in combustion , can temporarily block its combustion, and can avoid slagging in the furnace of the circulating fluidized bed boiler. This method can manually introduce low-pressure saturated steam at any time according to needs. Of course, low-pressure saturated steam can also be introduced into the furnace at regular intervals to maintain the effect of continuously avoiding slagging. This embodiment is easy to operate and low in labor intensity. Exemplarily, the preferred pressure of the low-pressure saturated steam in this method is 0.5 MPa, and the corresponding temperature of the low-pressure saturated steam can be directly...
