1.	Which system was used before direct firing system in pulverized fuel firing?(a) Unit system(b) Burner and pulverizer system(c) Bin system(d) PulverizerI had been asked this question in an interview for internship.Question is from Pulverised Fuel Handling topic in chapter Steam Power Plant of Energy Engineering
Answer» Right option is (c) Bin system For explanation I would say: Bin system was widely used before pulverizing equipment BECAME reliable ENOUGH for continuous STEADY operation. This system EMPLOYS a LIMITED number of large capacity pulverizes at a central point to prepare coal for all the burners.
