LMD-D92G Furnace arch ash blower is develop and newly designed by
LEMOND company in year 2018, it's outshape is kindly like D92
rotary sootblower, but design is different. LMD-D92G furnace arch
sootblower is specially desiged for the boiler arch of
supercritical boiler , as there is higher chance for ash deposition
in this field, if use retractable sootblower in this area, it will
lead a blowing dead angle and expand blowing quantity. If the
remaining ash didn’t remove on time, it has bad influence for
boiler effiency, so this type sootblower is your best choice for
the boiler arch field.
The Phenomenon And Harm Of Ash Accumulation In The Corner Of Folded
Flame:
A large amount of fine ash is often deposited at the bottom of the
flue at the corner of the horizontal flue, which not only has a
fast speed of ash accumulation, but also has a thickness of 1-1.5
m, sometimes even higher, forming a ash wall. If a ash wall is not
removed in time, when the ash wall reaches a certain thickness and
height, the cross-sectional area of flue gas flow at the furnace
outlet will be reduced, resulting in the reduction of flue gas flow
With the increase of furnace pressure, the heat absorption of
boiler tail heating surface decreases. The ash deposit in the front
of the folding flame angle is likely to collapse into the furnace
due to its own weight or the impact of flue gas flow. Although the
scattered ash does not cause a sharp drop in the furnace
temperature, it not only seriously affects the boiler efficiency,
but also is a potential threat factor to the stable operation of
the boiler. On the one hand, it may block the flame radiation in
the furnace and shield the normal detection of coal fire detector;
on the other hand, when it is serious, it directly impacts the
furnace flame center, blocking the mixing of wind and powder,
leading to combustion deterioration and even fire extinguishing.
Selection And Analysis Of Soot Blower:
Steam soot blower
Steam soot blower is also a traditional way of soot cleaning,
depending on the release of strong kinetic energy of
high-temperature steam, it directly injects the heating surface.
Steam soot blower is widely used in large units of power industry
Advantages: it can directly blow soot on the heating surface, with
strong adaptability and good effect on coking, slagging and sticky
ash.
