UNDERGROUND SMOKE FLUE. 



I have a brick smokestack, eighteen 

 feet high. The inside opening is 12x12 

 inches. I should like to change my flue, 

 because my neighbors complain of too 

 much smoke. Could I run a 10-inch flue 

 underground for forty feet and then run 

 this flue into the chimney of my dwell- 

 ing house, where the flue is 9x9 inches! 

 My boiler at present draws so hard that 

 the flames come out four feet if I have 

 the dampers open. I intend to have my 

 underground pipes arranged so that I 

 can clean them out every month if neces- 

 sary. W. H. 



I have never seen a plan of this sort 

 in operation, but it appears to me to be 

 the same in principle as the flue carried 

 around, a greenhouse, and such flues, 

 wnen well built and properly graded, 

 work well. If you can give the under- 

 ground flue a rise of from eight inches 

 to one foot in the forty feet, I believe 

 it will work. C. 



ESTIMATING RADIATION. 



In figuring on a boiler, how many 

 square feet of heating surface to the 

 foott One square foot of boiler hea&ing 

 surface vrill heat how many square feet 

 of hot water radiation f J. H. T. 



It is estimated that one square foot of 

 heating surface in a hot water boiler will 

 provide heat for eight square feet of 

 radiation in the heating system. 



If a pipe heater is in question, the 

 heating surface will depend upon the size 

 of the pipe used, each square foot of 

 radiation being supplied by two lineal 

 feet of 1%-inch pipe, or two and three- 

 tenths lineal feet of 1%-inch pipe, or onat 

 and three-fifths lineal feet of 2-inch' 

 pipe. . C.
