1.	Why nozzle tubes are provided in the soot blowers?(a) To moistures the dust(b) To admit high pressure steam(c) To blow away the soot(d) To suck in the dust and exhaust it at high pressureI got this question during an online interview.My question is based upon Soot Blowers in division Steam Power Plant of Energy Engineering
Answer» The correct choice is (b) To admit HIGH PRESSURE steam To EXPLAIN: The usual form for the smaller boilers is a dead-end tube projecting through the setting and extending into the tube banks. A number of small lateral nozzles are provided and the external HEAD is arranged so that high pressure steam can be admitted to the tube and at the same time the tube is rotated around its AXIS.
