Project Name:

Hsinta Power Station IndoorCoal Yard

Client

Taiwan Power Company

Location

Hsinta/Kaohsiung, Taiwan, ROC

Description

To mitigate local environmentalconcerns, an indoor-type coal

yard and all related handling

facilities for Hsinta Power Station

is constructed. The indoor-type

coal yard consists of four (4)

coal domes each with 170,000

metric tons of storage capacity

which enables the supply of coal

for existing four (4) units for 50

days operation.

While building coal domes the

project was divided into two

stages, in which domes,

conveyors, stackers/reclaimers

were constructed during the first

stage to handle coal supply by

barge and was transferred from

Talin, Kaohsiung Harbors;

further, at the second stage an

off-shored wharf with ship

unloaders and conveyors wereconstructed to realize the

complete coal handling system.

Hsinta indoor coal yard is built

on the reclaimed land from an

ash pond, with area of 12.27

hectares, in Hsinta Power

Station where four (4) coal

domes are situated. Each

dome is 120 meters in diameter,

67 meters in height, and is

equipped with one (1) radial

semi-portal type

stacker/reclaimer and

conveyors to handle

coal flow in/out.

Coal is unloaded from

an offshore wharf

which is connected by

a 2.3 kilometers long

of trestle-bridge from

power plant boundary.

The wharf is equipped

with two (2)

continuous ship

unloaders (CSU),each with 2,000 t/h

unloading capacity.

Two (2) 4,000 t/h

conveyors are

installed for the

handling of unloaded
