Combustion Linings Limited introduce a new concept in boiler door
linings. The FIBRE LINER technique uses our unique method to solve
the problem of renewing refractories on modern package-type boiler
doors. With this system boiler shutdown is reduced to a few hours
not days. There is no lengthy drying out or curing period required.
As soon as the work is completed the boiler can be fired. For example,
a small 660mm diameter door will take 3 to 4 hours to demolish the
old unit, fabricate and install the new lining and then switch on
the burner. It is not necessary to remove the old door or to disturb
the burner gun. Provided the door is reasonably cool and can be
swung open giving access to work there is no dismantling work involved.
Basically , the technique is to use ceramic fibre cut to size and
fixed with a specially developed heat-resistant cement. Fibre strips
are stuck on to form a tightly bonded refractory insulation which
is incredibly light in weight and withstands temperatures over 1600°C.
The system has been used on most types of boiler available in the
U.K. and has been approved.
Because the technique uses an angle cut fibre there is no heat
penetration between strips. This reduces heat on to the door steelwork
and keeps heat losses to a minimum. This means more heat is retained
in the boiler passes which improves boiler efficiency. This can
be as high as 12% which represents considerable cash savings after
a single heating campaign. For example a boiler with a 25 litre
per hour burner using gas oil at 15p per litre used for an eighteen
hour day would save £4 per day with A FIBRE LINER fitted at
6% efficiency saving.
Many boilers which have dry back combustion chambers can be fitted
with a fibre liner to reduce heat loss and improve furnace life.
Suspended roof liners can be devised to suit most requirements and
all light oil and gas fired boilers can be advantageously treated.
