This is irony of the situation in coal fired power plants. The coal along with many impurities (esp ash & moisture) is transported to the long distances and complicated, costly and unsafe system is made & operated handling the impure coal upto the combustion and post combustion. Much more is spent on pollution control as well. This all can be avoided by cleaning the coal at source and by building more power plants with simpler handling and systems either near to the mines or the coal can be transported by slurry. Why we should transport, burn and handle post combustion products with so many impurities and spend too much. lot of investment is made to handle hard ingredients (unwanted) of the bulk coal, lot of people are killed in the accidents due to explosions in the furnace, lot of pollution is generated. It seems that the presently used technology of coal fired thermal power plants was followed blindly and improvement was not taken up from the very beginning. If we clean the coal and separate all impurities and transport and burn pure or near to pure carbon, the process will be simpler, safe and less polluting as well as more cheap. Now it is must for the survival and use of the huge reserve of coal to go for cleaning of the coal before transporting and burning. More and more innovation and investment can be done on efficient cleaning of the coal (separation of coal ingredients)
