Question

Why is it necessary to observe temperature drops in the soot blower?

(a) To avoid net loss

(b) To avoid the soot getting struck in soot blower

(c) To avoid over usage

(d) To avoid overconsumption of electricity

This question was posed to me by my college director while I was bunking the class.

My query is from Soot Blowers topic in division Steam Power Plant of Energy Engineering

Answer 1

Correct choice is (a) To avoid net loss

To explain: It is necessary to observe temperature drops routinely. Obviously if the temperature drops 24°C after blowing, the interval might well be decreased, where as if 12°C were observed; it could represent a net loss because the value of the steam used was more than that of the increment of flue gas heat.
