KSPC Achieves Another Major Milestone: THE STEAM DRUM LIFTING OF BOILER UNIT NO. 1

K e

epco SPC Power Corporation completed another major project milestone

with the successful lifting of the steam drum of Boiler Unit No. 1 last May 29, 2009. Top management officials of KSPC, Doosan Heavy Industries and its sub-contractors attended the ceremony held at the construction site.

Before the drum lifting was performed, several preparations were done to make sure that the activity can proceed smoothly. First, the steel structure was completed and checked for its structural stability. This is one of the essential preparations to ensure that the steam drum is properly supported.

econd, the steam drum fabrication was completed on time as earlier

scheduled. Third, the steam drum underwent shop inspection tests to make sure that the drum is of reliable design and construction, and that this could withstand pressure during operations. Fourth, the steam drum’s packaging, transportation, handling and storage were carefully done to guarantee that there will be no damage to the parts. Fifth, the equipment used for the lifting was tested to make sure that this is capable of supporting the drum up to the specified height. After lifting the drum, pressure parts installation followed. These pressure parts included water and steam headers and furnace water walls, among others.

Coal Silo Shell Lifting of Boiler Unit No. 1

fter the steam drum lifting, the coal silo shell lifting of Boiler Unit No. 1

followed last June 5, 2009.

The coal silo is one of components of the fuel feeding system. It provides temporary storage of crushed coal for continuous operation. The coal silo is composed of the top frame, shell, middle shell, cone and chute.

Of these components, the coal shell is the only part fabricated at the construction site. The rest were fabricated at the contractor’s shops. Meanwhile, the two coal silo shells were lifted and installed in the boiler structure and then connected to the silo cone.

Before the shells were lifted, the shell plate dimensions, diameter, welded connection and painting quality, among other parameters were inspected to make sure that the specification was properly followed.

Coal Silo Shell Lifting (con’t.) Several preparations were also made before the coal silo shell lifting was conducted. The cone-chute-middle shell assembly was lifted first since it is located below the shell. The top frame was also installed above the shell as part of the fabrication plan.

Lifting the shell was not easy because the winds may cause the shell to abruptly swing and trigger the collision of the steel structure and the shell. If this happens, the shell and the steel structure may be damaged.

The other works related to the fuel handling system are now proceeding as scheduled.

Shop Test for Steam Turbine

T K

he steam turbine is one of the most important equipment in the operation

of the Cebu Power Plant. To make sure that all of its major parts will perform to its designed working condition, it is inspected and tested using the following methods: hydraulic pressure test, assembly inspection, over speed & dynamic balancing test, function test for actuators, ultrasonic inspection of generator rotor, and seat contact check for valves, among others.

The inspection and test of Cebu Power Plant’s steam turbine was performed in Japan where it is manufactured. This was done in the presence of the supplier, representatives of Doosan and KSPC in accordance with the approved Shop Inspection Test Plan and EPC Contract.

Prior to the activities, the Shop Test Procedures were submitted for KSPC’s approval. This started last February 25, 2009 while the succeeding tests were done after each test had been carried out and had satisfactorily passed the criteria.

Successful Completion of the Chimney Concrete Shell

F

or about a month of round-the-clock

construction, the chimney concrete shell was

successfully

completed.

The

construction of the chimney shell using the

modern

slip

forming

technology

started on May 4, 2009 and was finished on June 9, 2009 with the combined effort of a team of two dozen Korean and Filipino men led by a Hungarian. Blessed with a good weather, works on the reinforced concrete shell proceeded smoothly without any interruption.

Completion of the Chimney Concrete Shell (con’t.) After the successful erection of the reinforced concrete shell, the final works of the main structure of the chimney will follow. This will include the construction of its duct opening, the inner lining, stairs and platforms, among others. Surely, the 110-meter high chimney will permanently change the skyline of Naga and will standout as the landmark of KSPC’s Cebu Power Plant.
