|PAPER SLUDGE/PLASTIC WASTE FIRING CFBC BOILER
We have successfully installed boiler using paper sludge/plastic waste 500 ton a day at Tianjin City of China
in 2008. This papermill has 500 tons of waste materials from their process. 200 ton of paper sludge with
almost 74% water content, and 300 tons of waste plastic of mixture of screen reject, pulper reject and rag
rope which has a content of steel wired that must be removed first and water content is about 59%. In order
to reach required heating value and water average water content, coal of about 154 ton/day is mixed to have
the average water content of 51.36%. With this water content, heating value will become 2,113 Kcal/Kg.
|Hamada Boiler introduces plastic
waste firing FBC boiler for papermill
BANGKOK: In the year 2008,
Hamada Boiler went into a contract
with HIANGSENG PAPERMILL
of Thailand for building 25 ton/H
waste plastic firing BFBC boiler in
order to make use of huge quantity
of waste plastic coming out from
the recycling process of paper.
Boiler pressure vessel picture
shown at the right side is the model
DF25, bubbling bed FBC for 25
ton/H capacity. In addition to the
main screw feeder for the plastic
waste, it equip with spare feeder for coal fuel so that coal can
be mixed when the plastic waste contains excessive water in
order to maintain the furnace temperature at about 850 oC
at all time.
Right above picture is Mr. Hans Muhry, company's executive
engineer, inspecting the huge quantity of plastic waste
produced everyday from the process line. This is a common
problem to all papermills who uses recycled paper containing
plastics. Paper Factories who have similar plastic waste may
contact us for this latest technology.
This paper factory produces paper
sludge of almost 200 ton/day with
65-74 % water content and directly
used to the boiler without drying but
with coal mixture. If this sludge will
be dried, coal consumption will be
reduced accordingly.500 T per day waste firing capacity/

Tianjin, near Beijin China
China do not have the restriction
of transport of plastic waste and
this plant uses raw and wet
plastice waste as fuel.
This chart is the data of daily disposal of plastic waste from the waste
paper processing for carton box paper of one of the biggest factory in
Taiwan,. There are 3 kinds of wastenamely pulper reject screen reject
and Rage rope. Rage rope contains steel wires which must be
removed by magnetic steel separator. In Taiwan, government restrict
the transport of this kind of plastic waste if it is considered as industrial
waste. Therefore, this must be processed first to become RPF. The
ASPHALT MIXING PLANT
Most of Asphalt Mixing Plants by average consumes
600 Liters of oil per hour for the production
of 50 tons of asphalt mix per hour. Do you
want to cut this oil cost? YES, YOU CAN. We
can change your oil burner with very unique coal
burner with specially designed COMBUSTER.
Do you worry about the ash from coal? No problem.
In Indonesia, government issued certificate
that the ash from coal mixed to the asphalt can
be used as FILLER and the result is better than
the oil. SAVING CALCULATION: This is a
direct fire system.
How much are
you using for
Let's say 500
liters of bunker
oil or Diesel Oil?
Your saving will
be 80% of what
you are paying for at present.
We will bring revolution to all Asphalt Mixing Plants. We will
replace your oil burner with pulverized coal burner and the ash
from the coal will act as FILLER to make your asphalt mix better
quality. This matter has been proven in many asphalt mixing
plant in Indonesia with government certificates.
|PULVERIZED COAL BURNERN
FOR BOILER APPLICATION
Huge power plant boilers uses Pulverized
Coal Combustion technology.
We use the same principle but
do it on small scale application using
be used in
many types of heating equipments
as long as the ash can find the way
to be disposed, or the products to
be heated could accept ash, like in
the case of Asphalt Mixing Plant.

with the rotating combuster installed
in front of the smoke tube boiler.
