Reasons why the bed temperature is too high
Thread Content
Ask everyone for advice: What are the specific reasons why the boiler bed temperature of circulating fluidized bed boiler is too high? Thanks!
I suggest you tell me whether the temperature is too high at the lower boiling point, the middle boiling point, or the upper boiling point. It is more common that the material layer is thin, which will cause the boiling temperature of the furnace to rise for a short time, and it is easy to flameout if it is not controlled well. If the boiling temperature is extremely high, the canopy pipe may be scorched. The others will be added later. For reference.
The reason for the high bed temperature has a lot to do with the coal quality, coal supply volume, and air volume. Another reason is that the return material is not used properly.
