This is one man's 

 experience:— 



W. v. S.NKi.i., Mohawk, N. Y., Jan. lil, 1907. says:— 

 •I have to report In regard to the No. 407 Standard 

 Sectional Steam Boiler recently installed In my grreen- 

 houses, that It gives thoroug-h satisfaction. About 

 .Tanuary 1. I had occasion to note an incident that I 

 consider worth reportlngr. The boiler was attended to, 

 fuel furnished, grate shaken down aril everything 

 arranged for the night at l.i o'clock midnight. At that 

 time the boiler showed two lbs steam. To test the 

 boiler and see how long it would run without attention, 

 I deferred giving it any further attention until 11 o'clock 

 the following day. At that time the fuel needed 

 replenishing, but steam had been maintained in the 

 system practically ail the time and ai the time it was 

 replenished, the gauge stood at two lbs. pressure. The 

 experiment showed that the boiler ran without any 

 attention whatever for eleven hours, carrying 7000 sii. 

 ft. glass to about 55 degrees. The wt-ather outside was 

 about zero."

There seems to be a good circulation. 

 The pipes rise at the rate of ten inches 

 in each eighty-five feet, and the fall in 

 returning is ten inches. A. M. S. 



Water at high temperature parts with 

 its heat more quickly than at a lower 

 degree of heat, and for this reason the 

 flow pipes at the north end of the 10-foot 

 houses have a greater efficiency than at 

 any other point in the houses. The eas- 

 iest method of correcting the present dif- 

 ficulty will be to decrease the number of 

 flow pipes and increase the number of 

 returns correspondingly. Under each 

 bench of the 10-foot houses place one 

 flow pipe, to divide at the south end into 

 two returns. This will provide for two 

 flow pipes and four returns, in addition 

 to the run which passes through the wall 

 into the middle house. This pipe passing 

 from one house to another is objection- 

 able and could safely be changed so as 

 to act as a return in both houses. This 

 would provide for two flows and five re- 

 turns in each of the 10-foot houses and 

 four flows and six returns in the middle 

 house. This arrangement will require 

 manifolds for connecting the flows and 

 returns at the south end. At the north 

 end the returns should be fitted with el- 

 bow joints to provide for variation in 

 expansions. L. C. C. 



FLOWS FOR HOT VATER. 



I propose to erect three greenhouses, 

 north and south and side by side, each 

 16x100 feet and t^\elve feet to the 

 ridge. I will pipe them for hot water, 

 with the boiler in a shed at the north- 

 west corner. According to my plan 1 



would have just one flow, which would 

 be placed under the ridge in the west 

 house and would supply returns in the 

 whole plant. What size of flow and 

 what size and number of returns do I 

 need to keep the temperature at 50 to 60 

 degrees? The temperature here, in the 

 state of Washington, is never known to 

 go below 9 degrees above zero. If I 

 should not be able to erect more than 

 the west house for the first winter, 

 would it be necessary to have a smaller 

 flow until the whole plant is up? 



C. H. 



A S^Xj or 4-inch overhead flow pipe 

 will be required to supply the three 

 houses, but it would be much more sat- 

 isfactory to run a 2-inch flow pipe 

 through each house, with a 4-inch main 

 in the potting she<l. The main return 

 pipe connecting to boiler will necessarily 

 be the same size for hot water heating 

 as the main flow pipe. The large flow 

 and return can be used with only onj 

 house. 



With a 4-inch flow in the west house, 

 this house will require six lines of 2-inch 

 pipe as returns. The middle house will 

 need six lines of 2-inch and the east 

 house eight lines of 2-inch pipe. If a 

 2-inch flow were run through each of the 

 houses, the m^dle one would require 

 five 2-inch returns and each of the out- 

 side houses seven 2-inch returns. All 

 pipes should be graded to a uniform fall 

 of about one inch every ten feet, the 

 drop being toward the bottom of the 

 boiler. The expansion tank should be 

 located at the highest point in the sys- 

 tem, which is usually just over the 

 boiler. The piping of each house should
