HEIGHT OF SMOKESTACK. 



What is the proper lieight for a brick 

 smokestack, twelve inches square inside 

 measurement, to provide draft for a 

 3x12 return flue hot water boiler? The 

 fuel is soft coal, half slack. The chim- 

 ney is to be twenty-four inches inside 

 measurement at the base. J. Y. L. 



There is no rule to govern the height 

 of a chimney save that the higher the 

 chimney, within reasonable limits, the 

 better the draft. Surrounding objects, 

 such as buildings and trees, have more 

 bearing upon the height of smokestacks 

 than any other single factor. The stack 

 should be high enough to escape eddies, 

 caused by near-by tall trees and build- 

 ings. If there is no obstruction of this 

 character near by I would say a stack 

 twenty-five or thirty feet high would an- 

 swer. L. C. C. 



RADIATION. 



I have a house 22x100 and twelve feet 

 to the ridge; side walls are five feet 

 high, two and one-half feet being boards, 

 the remainder glass. There are three 

 benches each five feet wide. What size 

 of pipe should I use, how many runs and 

 how place them to maintain a tempera- 

 ture of 60 degrees when the outdoor tem- 

 perature is 8 degrees below zero. 



G. S. B. 



A satisfactory way of providing heat- 

 ing surface for the house in question is 

 as follows: If 2-inch pipe is used, four- 

 teen runs will be required. A coil of five

Gentlemen:— You can stroncrly and unhesitatlnrly recommend the

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicago soon to take un 

 the vacuum system with you. Yours truly,

each can be arranged under each outside 

 bench, one pipe in each coil acting as a 

 supply for four returns. The middle 

 bench can be provided with a coil of four 

 pipes, a flow and three returns. This 

 provides more flow pipes than would be 

 required for the radiation. The house 

 can also be piped by using a single 

 3-inch flow pipe under the ridge and 



use. They call this new boiler the 400 

 series. It is designed to meet the de- 

 mand which has resulted from the con- 

 stantly increasing size of greenhouse 

 ranges. A single boiler will take care 

 of a big greenhouse plant. The boiler 

 follows the general style of their regu- 

 lar sectional series, but is larger and 

 stronger, containing a large amount of

overhanging heating surfaces within the 

 firebox, in addition to the large amount 

 of plain and corrugated surfaces form- 

 ing the walls of the firebox. There are 

 eight long direct flues over the firebox 

 and four indirect flues, two on each 

 side, which add materially to the heat- 

 ing surfaces. The heated gases travel 

 three times the full length of the boiler. 

 The front and back sections are made 

 in one piece, the intermediate section 

 being in half sections, as in their stand- 

 ard boiler used in so many greenhouses. 



HOUSE WITH TWO ROOMS. 



I am about to build a greenhouse for 

 growing miscellaneous plants and cut 

 flowers for a small village trade. I 

 would like to know how to arrange the 

 heating pipes. The house will be north 

 and south and will be 21x50, with 12- 

 foot sashbars. The side walls will be 

 four and one-half feet, with two feet of 

 glass. There will be two side benches 

 two and one-half feet wide and two cen- 

 ter benches five feet six inches wide. 

 Sixteen feet will be partitioned off at 

 the south end to run about 10 degrees 

 lower than carnation temperature, or 55 

 degrees at night. The hot water heater 

 will be placed in a shed at the north end, 

 four feet below ground level. Should I 

 run the flows along the eaves, under the 

 side benches, or just below the purlins? 

 What number of 2-inch pipes will be re- 

 quired here in central New York, where 

 the mercury sometimes falls to 15 degrees 

 below zero and occasionally to 25 de- 

 grees? C. E. B.
