The range of results available from the joint research activities under this project and
the attributes of the data obtained may be defined briefly as follows. This High
Performance Industrial Furnace Field Test Demonstration Project
4
dealt with various
types of furnaces — heating furnaces, heat treatment furnaces, and melting furnaces
for industrial use. The data for a pair of furnaces, an existing furnace and a furnace
in use for production, modified to function as (or be replaced by) a high performance
industrial furnace, were compared. The intent was to identify the effects and operating
characteristics of the new system introduced as a high performance industrial furnace.
Detailed data on the normal operation of the furnaces in similar situations were
to be collected in the first year of the joint research, followed by collection of long-
term running data for the furnaces in the second, third, and fourth years.
Figure 5.80
shows the execution scheme of the current High Performance Indus-
trial Furnace Field Test Demonstration Project. For the execution of joint research
activities, we first accepted a wide range of applications for this joint research project,
then examined the contents of the applications to determine which facilities would
be suitable.
Table 5.27
shows the basic schedule of this project. The budget of the
project for fiscal 1998 to 1999 was 3.9 billion yen (approximately $32 million U.S.)
per year (see
Table 5.28
).
The results of case analysis of the joint research project
on the basis of the types of furnaces, industries, fuel, and burners are discussed
below.

Figure 5.81
shows the number of furnaces adopted for field tests in fiscal 1998 and
1999. The types of furnaces under the field test are divided into the three types,
namely, heating furnaces, heat treatment furnaces, and melting furnaces. In addition,
heating furnaces are grouped under the following categories: continuous heating
furnaces, batch-type heating furnaces, and ladles. Heat treatment furnaces are
grouped under the following categories: continuous heat treatment furnaces, batch-
type heat treatment furnaces, and gas treatment furnaces. Melting furnaces form an
independent group. Partly due to the difficulty of sorting the data according to the
groups, the seven furnace types mentioned above were designated for the analysis.
Analysis of the applications seemed to indirectly identify the respective indus-
tries' expectations toward the ease of introduction of and the great merits of high
performance industrial furnaces. The number of heat treatment furnaces exceeded
other types, with heating furnaces the second largest group. The total number of
applications adopted in fiscal 1999 was slightly lower than in fiscal 1998. The share
ratios of the respective furnace types in the 1998 and 1999 applications were almost
the same.
