1.	What is the advantage of using pulverized fuel firing system?(a) Decreases maintenance of plant(b) Less wastage of the products(c) Less ash formation(d) No formation of clinkersThe question was asked during an interview.Origin of the question is Pulverised Fuel Handling in portion Steam Power Plant of Energy Engineering
Answer» Correct answer is (a) Decreases maintenance of plant The explanation is: The use of pulverized system increases the capital of and operating COSTS, but decreases maintenance of the plant and increases thermal efficiency. The pulverizer used to GRIND the coal should CONSUME LESS power and should DELIVER the rated tonnage of coal.
