CHECKING/REMOVING CLINKERS
Wear gloves to prevent burns!
Clinkers are clumps of ash from burned coal
that have been fused together. Some coal is more
prone to create clinkers due to a low ash fusion
temperature. Coal that is prone to forming clinkers
can oEen be observed to increase the amount of
unburnt coal showing up in the ash pan, as pieces
of coal adhere to the fused ash and are removed
with the clinkers without being fully burned.
Higher combustion temperatures can also increase
clinker formation. /ese in turn are connected with
higher duty cycles, high grate temperature se ings,
and on belt drive systems, increasing the velocity of
the induction fan with non factory pulley
arrangements. Clinkers can be reduced or
eliminated by changing the se ings of the ash
controller on the boiler. Clinkers that are
approximately baseball size or smaller will be
carried to the ash pan. Larger sized clinkers could
cause the 1re to go out if the boiler is unable to
remove them.
To help remove large clinkers, remove the draE
@ap cover and move draE @ap to the side. Be sure to
wear gloves to provide protection against burns.
Insert a metal rod in the sight tube and run it up
and down (to the grate) through diDerent areas of
the coal pile checking for clinkers. Use the rod to
break up any clinkers you 1nd. If necessary, you
can use a hammer to strike the end of the rod to
break them up. You will not damage the grate if you
hit it as it is made of 1/2” steel. Once the clinkers
are broken up they will fall on to the grate and be
carried to the ash pan.
