1.	What is unit pulverizer system also called?(a) Burner and pulverizer firing system(b) Central system firing system(c) Bin system firing system(d) Direct firing systemThe question was posed to me during an internship interview.The question is from Pulverised Fuel Handling topic in division Steam Power Plant of Energy Engineering
Answer» Right answer is (d) Direct firing system To explain I WOULD say: The unit system is also called as the direct firing system. Most of the power plants with pulverized COAL as the FUEL are being installed with unit PULVERIZER. In this system each burner or a group of burner and pulverizer CONSTITUTE a unit. The over head bunker supplies raw coal by gravity into a feeder where it is dried with the help of hot air.
