Not Required
Major construction has occurred at the Kuei-yang Thermal Power Plant
since early 1966. Three boilers and probably three generators, additional
cooling facilities, switching yard equipment, and various support facilities
have been added. The plant will include eight boilers and eight turbo-
generators when all equipment is installed. The boilerhouse consists of
three sections, and the generator hall consists of at least two sections.
The increased requirements of the local power grid have been reflected in
the larger sizes of the boilers and generators which have been installed.

KUEI-YANG THERMAL POWER PLANT
'lr-j
The Kuei-yang Thermal Power Plant is located in Kueichow Province on
the southern outskirts of Kuei-yang, approximately 2 nautical miles (nm)
from the center of town. The plant supplies electrical power to the local
power grid. The Kuei-yang Railroad Yard and Station North
is located approximately I nm north-northeast of the plant.
Physical Features
The power plant encompasses an area approximately 1,500 by 1,150 feet
and is rail served. It is located in the bend of a stream and is secured
in part by a wall and some fencing.

The boilerhouse and generator hall are located at the center of the
plant complex. The roof of the generator hall has two levels, indicating
that there are at least two different types or sizes of generators in the
plant.. On imagery of April 1968, there were at least four and probably six
circuits between the lower section of the generator hall and the switching
yard and control house. From the higher section of the generator hall,
there was a single circuit to the switching yard. A support for a second
circuit was observed,indicating that another generating unit was yet to be
completed.
The boilerhouse has three sections, indicating that there are three
different sizes or types of boilers. Coal, the primary boiler fuel, is
stored in the open stockpile and in the coal processing and storage building.
The increased steam generation capacity of the plant has required a
related increase in cooling facilities. Originally, the quantity of-cooling
water pumped from the adjacent river was sufficient to condense the boiler
steam. However, as the boiler capacity increased with the addition of
more and larger boilers, the requirement for cooling water increased and
cooling towers were constructed. The boiler make-up water is diverted from
the river southeast of the plant. The make-up water then flows in an open
canal to. the plant area where it is drawn as needed to the water treatment
facility.
Various miscellaneous features within the plant area include a work-
shop,where ceramic insulators are probably made,and open storage of. probable
cable spools in the switching yard. A construction yard with a gantry
crane, northeast of the boilerhouse, has been utilized during the construc-
tion of the plant additions and was probably used for the storage and
assembly of boiler/generator sections.
Chronology of Plant Expansion
Since early 1966, the generator hall and boilerhouse have been enlarged
to accommodate probably three additional generators and three additional
boilers for a total of eight each. The boilerhouse expansion involved en-
larninn +ha ran+Ar section and adding a new (north) section. On photography
the additions to the generator hall and center boiler-
house section were under way. By September 1966, the walls of the generator
hall extension and the roof of the addition to the center boilerhouse
section were complete. The boilerhouse addition encompassed one boiler.
Additional cooling facilities including the pumphouse and western cooling
tower were also under construction. By June of 1967, the generator hall
addition, the roof of the northern boilerhouse section, the western cooling
tower, and the pumphouse all appeared complete. The framework of the center
cooling tower was evident on the June imagery and appeared complete in
August.

The obliquity of the August 1967 imagery provided a view of the end of
the northern boilerhouse section. To facilitate the installation of the
boilers, the northern wall had not been installed. Also at that time, the
installation of additional equipment in the switching yard appeared complete.
Two additional concrete transformer bases were evident, and the footings
of the eastern cooling tower had been started.
Between December 1967 and April 1968, one additional three-phase
transformer was placed in the switching yard, leaving one yet to be
installed. The workshop was constructed, and the probable cable spools
were put in open storage. Activity at the northern end of the boilerhouse
and generator hall in April 1968 indicated that the last turbogenerator and
possibly the associated boiler had not yet been completed.
Operational Status
The boilers within the northern boiler section have probably not been
in operation as no smoke has been observed emanating from the associated
stack.
Evidence of operation at the other two boiler sections was observed as
follows:
September 1966 - Light smoke was emanating from the two southern stacks.
June 1967 - Heavy smoke emanating from the southern stack obscured the
other stacks.
August 1967 - Heavy smoke from the center stack obscured the southern
stack. Vapor was emanating from twelve of the fourteen
throats of the western cooling tower.
September 1967 - Heavy smoke was coming from the center stack.
December 1967 - Moderate smoke was observed at both southern stacks, and
the western cooling tower was operating.
April 1968 - Moderate smoke was coming from the center stack. The
cooling towers were not operating.
Water turbulence was observed at the condenser water discharge on all
referenced imagery.
