32 659 MW Coal fired Power Ready Built in Indonesia
PT PLN (Persero) estimates the construction of coal-fueled power plants acrossIndonesia in the next 10 years will reach 32,659 MW. About 30% of that capacity will be a mine mouth power plant that uses lignite coal ismostly located in Sumatera.
what is a coal-fired power plants?
Coal Fired Power Station is one type of power plant installations where electric powerobtained from the turbine engine is turned by steam generated by heating by coal. Coalpower plant is the main source of electricity world today. About 60% of the worlddepends on coal power, this is because the coal power plant could provide electricity at a cheap price. The main drawback is the pollution from coal power plant carbonemissions is very high, higher than most other fuels. (http://wartawarga.gunadarma.ac.id/2009/12/pembangkit-listrik-tenaga-uap/)
I think coal-fired power plants was not good.
when viewed from the positive side, the electricity generated is good, cost is also quitecheap compared to other power generation such as nuclear power plants, and otherplants. however, the resulting pollution is far worse than other power both short and long term. as I quoted from antaranews.com that nine billion tons of CO2 (carbon dioxide)generated by burning coal in factories and power plants in the world, has been polluting the atmosphere every year. The figure was obtained by considering the assumptions of the world's coal consumption 5.3 billion tons per year, which is 75 percent of them to the needs of power generation, said experts on Climate and Sea Water Increase ITB, Dr.MT diDenpasar Susan Armi imagine, if it occurs in brackets within 100 years. earth's atmosphere will be destroyed and fatal to life on Earth.
coal-fired power plants are one of the biggest contributors to global warming. humanshould have to be conscious of it.

Clean coal combustion system
clean coal combustion system is one system of coal-fired power plants to reduce pollution that occurred. The working principle is the coal power plant that will be used / worn burned in the boiler in stages. This is intended to obtain a low firing rate and without reducing the temperature required to obtain low NOx formation. Coal before burning it rolled up to resemble grains of rice, then put into a container (boiler) by spraying, in which the basic shape of the container and a perforated grill frame.Combustion can occur with the help of a blown air from the bottom up and the speed of air inflatable arranged, resulting in grain brick embers carried slightly raised slightly without forming a layer of coal grains are floating. In addition to floating point is also moving coal means it indicates the occurrence of air circulation that will give good effect so that the grain was all burned. Because the coal grains relative has the same size and the distance of adjacent consequently it became a floating layer of heat is good.Because the low temperature combustion process so that the resulting NOx levels to be low, thus this combustion system can reduce the pollutant. When inserted into the boiler furnace lime (Ca) and from the bottom of the furnace the temperature of 750-950 ¼ C air entered the floating layer is formed as a result of burns. On that layer chemical reaction occurs that causes the sulfur bound with lime to produce CaSO4 in the form of dust, so easy to fall with ash. This causes a reduction in emissions to 98% and its ash CaSO4 can be utilized.
despite that, still no pollution around + - 5%, if in the long run will still damage the environment. unlike wind power, wave, or UV, plants are much more environmentally friendly and the results obtained are also maximal, the plant as that's what I really recommend the whole world, not just Indonesia
