Energy Conservation
Gas Engine Cogeneration Systems with the Highest Power
Generating Efficiency in the 100kW Class
Shinko Engineering
Co., Ltd. has added new, 100kW-class units to its SHINCOS-G Series
of gas engine cogeneration systems. Cogeneration systems use gasoline
engines or other power sources to generate electricity, while simultaneously
recovering waste heat from engine operation for reuse. In this way
they achieve energy efficiency of 75% to 85%, compared with 30% to
40% for conventional systems. They are therefore at the center of
attention in the field of environmental conservation.
Shinko Engineering has developed two new models, one rated at 115/kW/50Hz
and the other at 118kW/60Hz. Both are highly efficient at recovering
hot water and, when used in combination with hot-water heaters or
hot-water absorption chillers, make excellent heat sources for air
conditioning applications.
Incorporating gasoline engines manufactured by Germany's MAN Group,
these cogeneration systems are extremely reliable. They also feature
a built-in control panel that reduces overall unit size by approximately
10%.

Active Vibration Control Device for Use with Reciprocal
Motors
In 2002, Shinko Electric
Co., Ltd. became the first company in the world to use a reciprocal
motor in an active vibration control device that economically and
easily reduces equipment vibration.
Because the device uses a reciprocal motor instead of springs and
dampers, it can be easily adjusted with a controller for ideal motion
absorption without requiring detailed spring design and manufacture.
In addition to offering superbly efficient and adaptable control,
the device has no bearings or other moving parts that are subject
to wear and uses no oil, thereby minimizing mechanical energy loss
and dust generation. These excellent features make the active vibration
control device ideally suited for applications in semiconductor and
liquid crystal manufacturing equipment, robots, machine tools, automated
handling systems, and many others. Compact and easy to operate, it
can be installed on existing machinery by non-specialists.

New Emeraude ALE-v Series
Kobe Steel has come out with a new, improved
line of Emeraude ALE-v Series oil-free inverter compressors that feature
a new line pressure control function. The operator merely enters the
required pressure in a monitoring device to activate sensors that
track changing pressure loss and make the adjustments needed to keep
the pressure steady. This function ensures that each separate compressor
maintains optimum output pressure for highly energy-efficient operation.
Also, the newly designed two-stage compressor body unit, which features
reduced in-package pressure loss, offers an 8% improvement in efficiency
compared with previous models. Low pressure drops are reduced to one-fifth
previous levels through the adoption of a water-cooled intercooler
and aftercooler utilizing a plate-fin design. A logic program for
energy efficiency is included as standard to reduce electric power
consumption, and a permanent-magnet motor has been adopted for the
first time in the industry for better efficiency than can be obtained
with a high-efficiency induction motor. Energy efficiency is further
boosted by the use of a specialized inverter, making the Emeraude
Series compressors extraordinarily efficient to operate.

Hydraulic Ram Type Rubber Mixer Reduces Energy
Consumption
Kobe Steel supplies the world with many energy-saving
products. One of them is our hydraulic ram type rubber mixer (a weighted
vertical rubber mixer) which is designed to increase productivity
while reducing energy consumption. Nearly 100 of these have already
been sold (30 in Japan), realizing a savings of about 3 million kWh
per year.
