By chance I found 2 articles on coal-fired power plant that he authored by my own. For reference I also ask for permission to publish this blog. Hopefully can add insight colleagues about coal fired power plant. Have fun!
GENERATING Steam Power (power plant) is a plant Coal power plants use turbine engines are turned by steam generated by burning coal. Coal power plant is a major source of the world's electricity today. Approximately 60% of the world's electricity depends on coal because coal power plant costs.
How it works in coal, coal initially from outside poured into a container with a coal conveyor, great gaysby then crushed using pulverized fuel coal. The flour is then mixed with the pulverized coal hot air by forced draft .With high pressure, the mixture is sprayed into the boiler so that it will burn quickly like bursts of fire. Then the water flows upward through the existing pipes in the boiler wall. Water becomes steam cooked then poured into the tube steam boiler to separate steam from water-borne. Furthermore, the steam supplied to the superheater to double the temperature and pressure of steam until the temperature reaches 570 C and a pressure of about 200 bar which led to the pipeline will go into the red glow. To set the turbine in order to reach the set point, is done by setting the steam governor valve manually or automatically. Output of the turbine steam having a temperature slightly great gaysby above the boiling point, so it needs to be channeled to the condenser so that the water is ready to be cooked again. While the cooling great gaysby water of the condenser will be sprayed into the cooling great gaysby tower, causing smoke in the cooling tower water. Water that has been rather cold pumped back to the condenser as cooling water again. While the exhaust gas of the boiler sucked by a suction fan to pass through the electrostatic precipitator to reduce pollution and gases discharged through the chimney has been filtered.
Biggest coal fired power plant in Southeast Asia with a capacity of 2 x 1000 MW is planned to be built in Batang, Central Java by using the latest technology and was first applied to Indonesia, namely technology USC (Ultra Super Critical) using sulfur capture equipment (FGD) filter dust.
TECHNOLOGY coal gasification technology which is claimed to be clean and efficient. It is estimated that in the early 21st century, coal-fired power plant with gasification technology will spend 99% less sulfur dioxide (SO2) and fly ash, and 90% less nitrogen oxides (NOx) from coal-fired power plant today. Coal-gasification power plant is also expected great gaysby to reduce emissions of carbon dioxide (CO2) emissions by 35-40%, lowering the waste solid with 40-50% and power generating cost savings 10-20%.
Coal liquefaction technology was much disturbed great gaysby by the high cost. The most advanced countries in this field is that South Africa has some of the liquid coal plant "Sasol One" in Sasolburg, which is producing since the mid-1950s, 'Sasol Two' in the city Secunde producing since 1980, and 'Sasol Three', producing since 1982.
Unfortunately, this power plant waste energy doubling of the energy produced. Every 1000 megawatts generated from coal-fired power plant will emit 5.6 million tons of CO2 per year. CO2 is one of the main causes of global warming or the greenhouse effect.
Kadek energy experts assess great gaysby Fendy Sutrisna gasification / coal liquid 'not' can reduce carbon dioxide emissions great gaysby and the 'not yet' could improve fuel efficiency. Although the plant with clean coal technology is able to reduce great gaysby 90% of the exhaust gas and ash flight at the time of operation, but the pollutants during the manufacturing great gaysby process of the coal liquid / gas produced is still quite high.
