Coal Fired Power

Coal Fired Power Station is one type of power plant installations in which the turbine engine derived from that played by the steam generated by heating by coal. coal-fired power plants are the main source today listrikdunia. About 60% of the world depends on coal power, this is because the coal plant could provide electricity at low prices.

The main disadvantage is the pollution from coal-fired power plant carbon emissions is very high, higher than most others.

when capacity reached 400 MW power plant, fuel is not using more oil but coal. Coal is widely used is divided into two parts, namely high-quality coal and low-quality coal.When good quality coal is used will produce very few harmful substances, so it is not so pollute the environment. Medium if coal is used it will be a lot of low quality produce harmful substances such as sulfur, nitrogen and sodium. Moreover, if incomplete combustion will produce less toxic elements such as CO, as a result of low efficiency.

Total coal consumption will certainly determine the cost of power plant construction. The price of coal itself is determined by the heat value (Kcal / Kg), which means that if the heating value remains then the price will go down 1% per year. Medium heating value is determined by the content of SOx substance which is toxic, so the generator must be equipped with a vacuum SOx This is what causes the power plant costs up to 20% higher than petroleum plants. When coal is used in low SOx content of the plants will not need to be equipped with vacuum power plant SOx thus prices can be cheaper. Pembankit Excellence is a cheaper fuel than oil and its reserves are available in large numbers and spread all over Indonesia.

Opinion from reading the above

Coal-fired power plants contribute to the greenhouse effect and contribute enormously to global warming. Coal produces greenhouse gases at least three times more than natural gas.CO2 (carbon dioxide) generated by burning coal in factories and power plants have been polluting the atmosphere every year.Coal is also the largest source of emissions of carbon dioxide (CO2) which is the main cause of global warming.communities living around the coal-fired power plants to suffer respiratory and other health problems.
