Problem raised The circulating fluidized bed boiler slag discharge pipe produced by Jinan Boiler Group uses heat-resistant steel pipes. Due to the layout of the air distribution and water-cooled wall pipes, the slag discharge pipe is centered There is no wind cap within the diameter
range to prevent local coking of the slag discharge pipe. There are
small tubes in the pipe that are connected to the air chamber. In actual use, it affects the smoothness of slag discharge. Most users remove the
small tube. In this way, due to poor local fluidization of the slag discharge pipe, it is easy to coke on the top, affecting normal slag discharge and affecting the safe operation of the boiler.

Transformation plan
The new slag discharge pipe hood structure as shown below is made of rare earth high chromium nickel nitrogen heat-resistant cast steel, which has good high temperature resistance.
Installation instructions: Cut off the upper part
of the original slag discharge pipe, enlarge the air distribution plate hole that the original slag discharge pipe passes through to
, and replace the above-cut part with the new slag discharge pipe hood. The pipe is ready to be welded and poured (as shown below).
Principle Description There is a
gap between the piece
and the piece
, and the wind in the air chamber passes through the gap from
The small hole sprays out and plays a fluidizing role, thus preventing local coking of the slag discharge pipe.
