4.1 HISTORICAL TRANSITION OF INDUSTRIAL

FURNACE TECHNOLOGIES

Ev ery avenue of development of energy-saving technologies has been pursued since

the oil crises. Discussions on new technologies at the Third Conference of Parties
(COP3) promoted further incentives. Even in the field of industrial furnaces, the
foundation of industry, a high performance industrial furnace applying high temper-
ature air combustion technology has reached the stage where it can be put to practical
use. This innovative high performance industrial furnace is having an impact on
both conventional industrial furnaces and the instrumentation control technologies
for combustion in terms of reducing energy consumption.

4.1.1 E T D COP3

NERGY ECHNOLOGIES ISCUSSED AT

T o meet the problems of carbon dioxide emissions in 2010, many models and results

from private and government bodies such as the Environment Agency, the Ministry
of International Trade and Industry (now called METI), the Japan Energy and Economy
Research Institute, and the Electric Power Central Research Institute were discussed.
The models and results are now being compared and evaluated for the basis of the
final program. Table 4.1 shows a list of energy technologies considered in the AIM
end-use model by Matsuoka and others. It can be seen from this table that recent

technical progress has been remarkable in service technologies such as electric auto-
mobiles, hybrid cars, fuel cells, solar-utilized systems, repowering of private power
generation, latent heat recovering thermal components, and high performance indus-
trial furnaces. With advances in these technologies, the equipment cost and running
cost of the technical installations have decreased remarkably. In many cases, these
costs were the result of defects related to the new technologies. For example, a
cogeneration system for domestic use is being widely disseminated by manufacturers,
proving its cost effectiveness. This is along the same lines of technology developments
as in fuel cells and micro gas turbines for domestic use.
There is a possibility that the high temperature air combustion technology for
industrial furnaces can be applied to all types of combustion and heat transfer
technologies. It is considered that in the future this technology will be related to the
greater portion of the technical items listed in Table 4.1.
