CONTRADICTING theory based on general principles and research that
eventually designates hidden intention apart from the necessity of a coal
fired power plant to boost the shortage of electricity in the east coast
COAL must transforms the various types of energy that goes through
different kinds of apparatus before electricity is generated. Coal is
burnt to heat a boiler tank, to produce pressurized steam that goes
through a regulating and filtering system before it is channeled to rotate
a turbine's blades with a shaft, coupled directly to the electric
The results from burning of coal for the purpose of generating electricity
often come in a form of chemical compound with the most prevalent being
carbon dioxide, sulfur dioxide and nitrogen oxide.
To lesser extent, can also include carbon monoxide, mercury, arsenic, lead
cadnium and uranium. All of these have potentially negative impacts on the
environment. Carbon dioxide in large quantities can tip the atmospheric
balance and lead to the trapping of additional heat in the atmosphere, so
it will become hotter near ground level.
Sulfur dioxide can cause more localized problem such as acid rain which
can kill entire forest, ruins the surface of buildings and vehicles.
Nitrogen oxide is dangerous at lower levels where people live, at lower
altitude, ozone create smog and can trigger asthma attacks in those prone
to them. Thus, it's considered a public health hazard.
Though steps have been taken to reduce coal emission in most country, the
problem is still a major one in some part of the world, especially China,
though to have claimed can control coal emission cheaply.
Why did TNB pick to choose steam turbine instead of GAS TURBINE
or DIESEL ENGINE? Why did'nt they choose a GAS
TURBINE that can directly be fueled with liquidified petroleum
gas that is readily available from PETRONAS or a diesel
engine driven generator, both with much lesser impact on the environment
and public health.
The only reason why TNB had choosen steam turbine is, it's cheaper to
maintain even though they would have to import the coal from
INDONESIA. This so called CHEAP MAINTENANCE CANNOT
JUSTIfIES RISK TO PUBLIC HEALTH AND HARM TO THE ENVIRONMENT. What
happen if the oil price rises? price of coal also rise and so is shipping
According to mineral and geoscience report on the evaluation of coal
potential in the PINANGAH (N.47 KUAMUT) area of 500 sq km, were divided
into 4 blocks namely south block, west middle block, north block and east
West middle block alone yields an indicated reserve totalling 34 millions
tonnes of coal deposited in 6 seams. The chemical analysis on 77 coal
samples shows the coal rank are within the high volatile A - C range and
suitable for power plant generation.
Now, what can we tell about this? Do you think that there's something
fishy in TNB insistant to use a coal fired steam turbine? I'm not
surprised they had moved the site nearer to the coal region. If a
COAL MINE is the the answer, what will the KUAMUT
people have to say about this? Anyway, by the end of the day,
it's only a matter of theory.
