FISHER BUILDING 



Greenhouse Heating. 



It takes probably an average of a car 

 of Pocahontas coal for each 4,000 square 

 feet of greenhouse glass per season — and 

 there are few greenhouses that can not 

 buy in carload lots to advantage. 



Subscribers are invited to write tKe 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Eeview is a good boiler, and 

 the advertisers sell them on their merits. 



UNDEBGBOUND MAINS. 



We have a greenhouse, 27x80, which 

 we have been heating by a boiler in 

 the west end of the house. Twenty feet 

 west of the house we have a boiler pit, 

 about ten feet deep, where we wish to 

 place the boiler. We wish to connect 

 the house and the boiler pit with a con- 

 crete tunnel. North of this house, 

 which we shall designate as No. 1, 

 and separated from it by a 12-foot 

 driveway, we are going to build house 

 No. 2, 27x100, also to be connected to 

 house No. 1 by a concrete tunnel. Our 

 problem is this: How large a pipe must 

 we have to supply these two houses? 

 No. 1 has about 600 feet of radiation; 

 No. 2 will have about 900 feet. The 

 boiler has two 4-inch flow openings and 

 four return openings. We can join the 

 two 4-inch flow openings and connect 

 with a tee to a larger pipe, again re- 

 ducing to 3-inch after getting into the 

 greenhouses. Of course we could use 

 4-inch pipes, two for flows and two for 

 returns, but we do not wish to build 

 the tunnel wider than necessary. What 

 size of pipe will take care of this radia- 

 tion? The fall between the lowest coil 

 in the greenhouses to the top of the 

 boiler will be about six or seven feet. 



We have some 14-inch wrought-iron 

 pipe which we wish to use for a smoke- 

 stack. We are thinking of setting this 

 pipe in, .a concrete pier, 4x6 feet, run- 

 ning the pipe into the side of the pier 

 and then up thirty feet. Can this be 

 done without ruining the concrete by 

 the expansion of the 14-inch pipe, 

 heated by fire under the boiler? Our 

 location is northern Illinois. B. B. 



When there is a drop of six or seven 

 feet, there should be no difficulty about 

 taking care of 1,500 square feet of 

 radiation by means of a 5-inch flow and 

 return. The flow can be continued of 

 the same size to the farther end of the 

 first house, where a 3-inch pipe could 

 be taken oflE and this broken up into

three 2i4-inch pipes for supplying three 

 return coils, each containing four 2- 

 inch pipes. Then continue the flow 

 pipe through to the farther end of the 

 second house, after reducing it to 4- 

 inch. In addition to the radiation from 

 the flow pipe, four coils of four 2-inch 

 pipes each will be required if a tem- 

 perature of 60 degrees is desired, or 

 twelve returns will suffice if a tempera- 

 ture of 50 to 52 degrees is all that is 

 needed. 



If preferred, the flow pipes for the 

 first house could be taken off as soon 

 as the main reaches it, in which case 

 the three 2 ^^ -inch flows should be run 

 to the farther end of the house and 

 connected with the coils, which would 

 only require three 2-inch returns each. 



If the smoke pipe rests upon a steel 

 plate on the top of the pier, there will 

 be no trouble from its expansion. 



THE FUEL MABKET. 



There has been this week no impor- 

 tant change in the market for coal. 



Additional buyers have come into the 

 market as reserve stocks accumulated 

 before the April 1 shut-dow^are used 

 up and this has served touelieve the 

 pressure to sell coal on the rail; the 

 snaps for the cash buyer are not so 

 numerous as they were. The prices are 

 pretty well maintained at the slight ad- 

 vance that went into effect after the 

 wage disputes were settled. 



In the last week many in the green- 

 house trade have engaged their season's 

 supply — the average grower nowadays 

 wants to fill his sheds during summer, 

 and keep them full almost to the end 

 of the season. Even with a good reserve 

 supply there are apt to come times 

 when severe weather interrupts ship- 

 ments from the mines and the worry 

 point is reached. For instance, after 

 last winter's severe cold spell was a 

 month old one of the largest places in 

 the west found itself down to only two 

 days' supply in some of its sheds, al- 

 though dozens of cars had been shipped. 

 Of course no florist of standing ever 

 froze up because of inability to get
