1. A coating drier facility, comprising:
a drier chamber configured to dry a coated object;
5 a heater for heating air;
an air supplier for supplying the air heated by the heater into the drier
chamber; and
an air collector for collecting air from the drier chamber,
the heater including:
10 a heat exchanger configured to heat a portion of the air that the air
collector has collected; and
a combustion chamber configured to combust a remaining portion
of the air that the air collector has collected to decompose a volatile substance in
the remaining portion,
15 the coating drier facility further comprising:
a first heat receiver for recovering heat from exhaust gas from the
combustion chamber; and
a second heat receiver for recovering heat from exhaust gas from the first
heat receiver,
20 the first heat receiver being configured to preheat the remaining portion
before the combustion chamber combusts the remaining portion.
2. A coating drier facility, comprising:
25 a drier chamber configured to dry a coated object;
a heater for heating air;
an air supplier for supplying the air heated by the heater into the drier
chamber; and
an air collector for collecting air from the drier chamber,
30 the heater including:
a heat exchanger configured to heat a portion of the air that the air
collector has collected; and
a combustion chamber configured to combust a remaining portion
of the air that the air collector has collected to decompose a volatile substance in
35 the remaining portion,
the heater including a combustion air amount adjusting mechanism
configured to adjust an internal temperature of a combustion treatment furnace of
the heater so that the internal temperature is within a predetermined range.

3. The coating drier facility according to claim 2, wherein
the predetermined range is from 800°C to 1000°C.
45 4. The coating drier facility according to claim 1, wherein
the heater further includes:
a fuel amount adjusting mechanism; and
a combustion air amount adjusting mechanism.
16

5. The coating drier facility according to claim 4, wherein
5 the combustion air amount adjusting mechanism adjusts an internal
temperature of a combustion treatment furnace of the heater so that the internal
temperature is within a predetermined range.

10 6. The coating drier facility according to any one of claims 1, 4 and 5, further
comprising:
an outside air receiver for introducing outside air into the drier chamber,
the outside air receiver including an outside air introducing amount adjusting
mechanism.
15

7. The coating drier facility according to claim 6, wherein
the second heat receiver is configured to preheat the outside air that the
outside air receiver has introduced.
20

8. The coating drier facility according to claim 6 or 7, wherein
the heater further includes a combustion air amount adjusting mechanism,
and
25 the coating drier facility controls the outside air introducing amount
adjusting mechanism and the combustion air amount adjusting mechanism so that
respective amounts of the outside air and combustion air are substantially equal
to each other.
