Coal Silo Shell Fabrication

O

ne of the components of the power plant is the fuel feeding system. And

part of the fuel feeding system is the coal silo. The coal silo is composed of the top assembly, the shell, and the chutes (cone) where the coal is directed to the fuel feeder.

The construction of the coal silo is not easy. First, because the height of the steel plates used for the silo shell is shorter than the desired total height of approximately nine (9) meters, the shell has to be divided into four (4) crosssections.

Coal Silo Shell Fabrication (Con’t.)

S

econd, bending the plates to form a circle is difficult due to the resistance

of the material. Temporary lugs and retainers were installed to make the ends meet and be joined by welding.

Third, joining the shell parts is another challenge since these parts were eccentrically different. With this the joints were welded using guide stops systematically to achieve conformity with the other parts.

Last March 2, 2009, the fabrication of one of the coal silo shells was started. After the completion of the coal silo shell, the top assembly and the chute (cone) will be installed.

Circulating Water Facility

T

he excavation work for the circulating water facility has been started in

the month of February 2009. The function of the facility is to allow sea water entry into the plant to be used for the cooling of mechanical equipments and source of freshwater by means of the desalination system.

Basically, this facility will be provided with water pumps that will supply the sea water to the power plant. After the sea water absorbs the heat from designated equipments, the sea water will be discharged back to the sea. This facility will also supply the water to be used in the production of steam for driving the steam turbine.

Since the sea water is very corrosive and contains many harmful impurities, it has to be treated and be converted to soft water. With this, all the water requirements for the power plant will be sea water treated to meet requirements for an efficient and economical operation.
