Question

Using which of the given formula the chimney height is calculated to get the answer of 67.4m when the coal burnt is 18.8TPH and considering 0.5% of sulfur content in coal?

(a) H = 12(Q)^13

(b) H = 17(Q)^13

(c) H = 14(Q)^13

(d) H = 22(Q)^13

The question was posed to me in homework.

Question is from Draught System topic in chapter Steam Generators & Accessories of Energy Engineering

Answer 1

Correct answer is (c) H = 14(Q)^13

The best explanation: Given: Coal = 18.8TPH (ton per hour) = 18800kg/hr
