Prashant Modi – The Process Of Generating Electricity With
Natural Gas
The primary non-residential use of natural gas is electricity generation. Prashant Modi says that
globally, there is an ever-increasing need for electricity, which is coupled with the high costs of solar
and wind energy, the tightening limits on noise, water, and air pollution, and the reduced tolerances
for hydro and nuclear plans. This has resulted in gas-fired electricity generation becoming one of the
very few options left for utility companies. Because the price of fuel accounts for almost two thirds of
the price of electricity, the cost-effectiveness of the fuel used for its generation is of paramount
importance.
Coal has been the dominant fuel for many of the electricity power plants around the world. However,
the biggest drawback of this fuel is the pollution which it emits during combustion. Modern natural gas
electricity plants are much cleaner, not to mention far more efficient than coal plants. They are also
cause less pollution and noise, and are cheaper to construct. Prashant Modi also says because of
these factors, obtaining permits to build these plants is normally far easier than it would for the
construction of a nuclear or coal plant.
There are several different kinds of gas-powered electric plants, including steam power and combined
cycle plants. In a conventional steam power plan, the natural gas is placed in a steam generator,
which then produces steam that powers an enormous turbine, which subsequently generates
electricity. During this process, the generator produces waste heat, and the turbine low pressure
steam. The latter can sometimes be used for heating, if the demand exists however it cannot be used
to generate more electricity.
In contrast, combined cycle plants generate electricity directly from a natural gas generator, after the
gas is burnt in a turbine. Power is also generated from steam, which is produced from the heat of the
natural gas generator. Because natural gas generators always run at very high temperatures,
Prashant Modi says that the steam generated from the heat of the turbine has enough energy to drive
a second steam powered turbine. Therefore, combined cycle plants are generally thought to be the
most efficient natural gas electricity plants.
