Why is direct firing system considered better than bin system in pulve

1.	Why is direct firing system considered better than bin system in pulverizer fuel firing?(a) It has long operating procedure(b) The auxiliaries used in system consume large amount of power(c) The initial cost of system is very high(d) The transportation of coal is much more complexThis question was posed to me during an interview.The query is from Pulverised Fuel Handling topic in division Steam Power Plant of Energy Engineering
Answer» Correct answer is (a) It has long operating procedure The explanation: The BIN system INVOLVES many stages of drying, storing and transportation and HENCE the process takes extra AMOUNT of time & chances of fire hazards are more. Never the less, it is still in use at many older plants.
