country promotes action to counter Global Warming and Climate Change
by reducing the CO2 emission.
In the pulp and paper company industries, the energy conservation
has promoted by the conversion of the conventional oil or coal
to the recycling reused waste fuel.
About the tire derived fuel (TDF), the amount of domestic generating
is about 1 million ton per year and the about 87% is recycled.
In recent years, TDF is expected as the power generation utility
the amount of recycling tire for thermal utility is reducing with
decrease in production of the cement maker who is a large user
Under the promotion of environmental protections, MHI has developed
the TDF fired bubbling fluidized bed boilers, and those are operating
as a power generation boiler of the pulp and paper companies.
MHI’s TDF fired bubbling fluidized bed boiler has the technologies
of continuous stable discharge of the steel wire which is included
10〜20% in a TDF without the deposition on the furnace bottom, and
of the low environmental load combustion by the M-STAR method (Multi-Stage
Air Re-firing Method: patent of Mitsubishi ).
Especially in this paper, we introduces about the outline of the
development circumstances and an actual operation result.

The Features of Our Large Sized Drum Less Water Tube Boiler “Ifrite”
Series and It’s Example of Application to the Corrugated Paper
Boiler Engineering Department, Boiler Engineering Office,
Kawasaki Thermal Engineering Co., Ltd.
In recent years, multi-sets
of a small type drum less water tube boiler were installed more often
for the purpose of
and laborsaving of a boiler facility, since it is convenient. Moreover,
in order to aim at improvement in synthetic thermal efficiency
of the facility using the steam, the heat recovery from
the drain of
the used steam is performed briskly.
Since this drain has a heating value equivalent to about 40% of
the latent heat of vapourization, whether this is reused effectively
influences the thermal efficiency of the whole facility greatly.
The corrugated paper production equipment needｓ the steam of the
pressure of about 1.27 MPa, and in order that it may perform the
heat recovery from a high-pressure drain, the water tube boiler
or the flue and smoke tube boiler has been used for some time.
Then, our large sized drum less water tube boiler has both the
convenience of a small type drum less water tube boiler, and the
which the water tube boiler or the flue and smoke tube boiler has.
We introduce the features of our large-sized drum less water tube
boiler and the example of application to the corrugated paper production

process has been known as an effective treatment process for organic
wastewater instead of the activated
Methane fermentation process uses some kinds of anaerobic microorganism
and they resolve BOD which is organic compound in wastewater into
methane and carbon dioxide. Oxygen consumption for BOD treatment
is unnecessary for this process and surplus sludge amount is much
smaller than the activated sludge system. And biogas recovered
from methane fermentation has mainly methane gas and it is
high quality fuel.
But because effective accumulation method of microorganism into
anaerobic reactor has not known, methane fermentation process has
for limited application.
In 1980’s Up Flow Anaerobic Sludge Bed (UASB) process has developed
and spread as effective wastewater treatment process. UASB process
uses anaerobic granular sludge in which some kinds of anaerobic
organism are naturally accumulated and the treatment capacity of
UASB is ten
to twenty times higher than the activated sludge system. In Japan,
UASB process has applied to food processing including brewery and
big UASB plant for treatment over 20ton-BOD/day has been built.
In Europe and America many UASB plants are applied to treatment
and paper mill’s wastewater.
After 1995 UASB system has developed into some high rate types
and they has applied to much wider field than UASB system. IHI
a high rate anaerobic system which call Internal Circulation reactor
(IC reactor) for some kinds of industrial wastewater like brewery,
Shochu distillery, chemical, general food process and pulp and
paper mill and proposed biogas recovery and utility system.
Some examples about biogas recovery and utility system introduce
in this paper.
High Thermal Efficiency Gas Engine Fuelled by Bio or Waste Origin
Niigata Power Systems Co., Ltd.
Engineering & Technology Center, GE Development
It is necessary to develop the high efficiency gas engine, which
uses bio or waste origin low calorie gas for effective use of
energy resources. The composition of bio or waste origin
low calorie gas
is composed of CH4, CO2 or H2, CO, CO2, N2, and others. Every
combustible gas has a possibility of fuel for internal combustion
if suitable combustion method is established.
The micro-pilot fuel oil ignition gas engine that uses a small
amount of marine diesel oil corresponding to a few percent of
the thermal input as the ignition source has a technically suitable
combustion concept for utilization of such gases with unstable
heat value. The great advantage of micro-pilot fuel oil ignition,
adjustable and high ignition energy, led strong combustion stability,
and a good thermal efficiency is achieved.

mills have "the activated sludge process" which
does microorganism treatment the effluent treatment process, and
our Nichinan mill uses this system as well.
It is necessary to activate a microorganism in this activated sludge
process by feeding oxygen(air) that consumes electric power.
There are three methods --- the surface aeration process, underwater
aeration process and diffuser pipe process. This report introduces
that energy saving is obtained by new modeldiffuser pipe using in
the activated sludge process in Nichinan mill.
Solution for Paper Machine Deposit Oriented Spot Prevention
Sales Engineering Dev, Maintech Co., Ltd.
Spot problems originate
from deposition of pitch, stickies and latex in the dryer section
is becoming a critical problem under
high DIP furnish, closed system and alkalization conditions.
These spots lead to production and quality problems such as
of broke and joint work. To date, only a few pitch control programs
have been tried, high-pressure fabric (canvas) cleaning showers
and double doctoring have been developed. However none of them
have met with industry-wide acceptance.
Maintech has developed a spot prevention program, a total solution
that passivates all surfaces in the paper machine where the deposition
could increase spots. The resulting surface passivation prevents
depositions on wire, felt, press rolls , cylinder, fabric and
calendar rolls and drastically reduces the number of spots on
can take considerable advantage of this program. Elimination
of deposits in the paper machine reduces not only the number
in the finished rolls but also reduced tonnage and down time
for M/C cleaning.
This paper reviews an investigative method of spot generation
from M/C deposition. Case histories illustrating gained benefits
paper board grade M/C are presented.

A mechanical seal
prevents or reduces outboard leakage of toxic chemicals and saves
energy and resources. Therefore, it can be
deemed as one
of the important environmental instruments that is directly and
indirectly contributing environmental preservation. In a pulp & paper
plant, many numbers of varieties of pumps are utilized such
as water pumps,
pulp pumps and chemical pumps all through the production processes
from digesting to painting.
In recent years, a mechanical seal has been selected as a standard
sealing device for such pumps. The maintenance of mechanical seals
is getting important. I will make brief explanation of the mechanical
