The Florists^ Review 



February 2. 1922 



properly insulated and placed under 

 ground, it is doubtful if the saving 

 would be enough to make the change 

 worth while. 



More attention should be given to the 

 insulation of the pipes as now arranged. 

 The use of corrugated asbestos pipe 

 covering and then enclosing them in a 

 wooden box would make considerable 

 difference in the heat that would be lost. 

 They could be placed underground, as 

 suggested, without any trouble. After 

 the main is carried to the height of a 

 foot or two above the top of the boiler, 

 a tee would carry the steam in either di- 

 rection. The only care needed would be 

 that the pipes leading to the houses be 

 given a slight rise so that the drip 

 water would run back to the boiler, 

 unless a relief pipe is used to connect 

 the mains with the returns. Even if 

 underground, the mains should be in- 

 sulated with corrugated asbestos pipe 

 covering, and either a sewer pipe or 

 similar tile should be placed around this, 

 so that the main will be kept dry. 



While it is possible to believe that the 

 trouble mentioned is due to the exposure 

 of the pipes, the trouble might also be 

 brought about by using mains too small 

 for the radiation, or by a lack of power 

 in the boiler. 



DIAMETER OF CHIMNEY. 



With a 7-section steam boiler which is 

 rated for 3,200 square feet of radiation, 

 how high a eliininey, 18x18 inches, in- 

 side diameter, would be required, also 

 a chimney 24x24 inches inside diameter 

 for the same boiler? Is it possible to 

 reduce a smokestack from eighteen 

 inches to fourteen inches inside dia- 

 meter and from fourteen inches to thir- 

 teen inches? Is a damper required 

 in the smoke collar as well as one in 

 the stack? A. S.— B. I. 



A chimney 18x18 inches should have 

 a height of about forty feet from the 

 floor of the boiler pit, for a boiler rated 

 at 3,200 square feet of steam radiation. 

 For the same boiler a chimney 24x24 

 inches need not be more than thirty feet 

 high, unless there are trees or high 

 buildings in the vicinity. A stack thir- 

 teen inches in diameter would only have 

 about one-half the capacity of one that 

 is eighteen inches and the capacity of 

 the boiler would be reduced in about 

 that proportion under the conditions de- 

 scribed, unless the smoke flue is quite 

 short. However, this could be over- 

 come by increasing the height of the 

 chimney. 



Although only one damper is really 

 necessary, it is often desirable to have 

 two dampers, as descril)ed.
