of converted crude oil or over 200 kVA according to the reports by the
Agency of Natural Resources and Energy, even if the estimated capacity
differs according to the kind of facility. The number of installed industrial
furnaces (cardinal number), excluding boilers and waste incinerators, has
decreased from the peak value in 1982 and was about 30,000 in 1992.
2. The number of industrial furnaces and facilities using fire and heat and
the energy consumption of the facilities, investigated by the Agency of
Natural Resources and Energy in 1975, show that the number of facilities,
excluding boilers and wastes incinerators, was about 33,300.

Table A.6
shows a comparison of the following three investigations:
a. The number of facilities emitting soot, as cited under the law of pre-
venting atmosphere pollution in 1992
b. Investigation by the Agency of Natural Resources and Energy in 1975
c. The number of facilities assumed statistically according to this inves-
tigation in 1995
The number of facilities with capacity using over 50 l/h converted crude
oil or over 200 kVA based on this investigation is about 35,300. About
