How Much Work Do You Get 



From Your Steam? 



AT some plants they spend good money in turning 

 water into steam, and then let the steam get 

 away w ithout its having done more than a lick or 

 two of work. That isn't business, although there are 

 plenty of successful establishments doing just this 

 thing. 



But at the very big and notably successful concerns, 

 where they keep a pretty close watch on the leaks, you 

 will find steam pumps, traps and an ever increasing 

 number of "Detroit " Systems. 



Wherever you find installed one of these means of han- 

 dling condensation you can be sure that steam is not 

 being allowed to escape into the atmosphere before it 

 has given something like a fair share of the heat that 

 has been put into it. Even the poorest of them will 

 cut enough from the coal bill to make its purchase a 

 highly profitable in\estment. 



But a "Detroit" System does not let any of the heat in 

 the steam escape unused and it requires very little 

 power to operate. It is absolutely automatic in its 



action and so simple in its construction that it is 

 almost impossible to conceive of its getting out of 

 order. 



The "Detroit" System is just as big an improAcment 

 over the steam pump as the steam pump was over hav- 

 ing no device at all. 



A steam pump handles condensation up to 212 degrees 

 — it saves 147 degrees (6j is probably as warm as tap 

 water is). The "Detroit" System handles condensa- 

 tion at about IMO degrees, or 13H degrees hotter than the 

 steam pump can take care of it. Think of the coal 

 saved by utilizing this waste heat (or iiower) that is 

 in the steam. 



You can see why there are "Detroit" Systems that 

 have paid for themselves in a month's time. 



There is an interesting book that not only shows the 

 saving a "Detroit" S.vstem can make, but tells just how 

 it improves the operation of a steam plant. Why not 

 ask for "Watch Your Condensation," Book No. 5- A?

six or eight inches fronf the top and

 ten feet along the back, then across 

 the farther end and along the front 

 of the bed to the end nearer the boiler. 

 Pipe as small as l^^-inch might be 

 used, placing a flow atid return on 

 each side, but this is rather small pipe 

 for hot water unless the frame is sev- 

 eral feet above the boiler. If l^^-inch 

 pipe is to be used, we would suggest 

 placing a flow pipe on each wall and 

 then connecting each of them with a 

 return located two feet from each wall, 

 six inches below the surface. 



STEAM OR HOT WATER? 



I have a range of four houses, run- 

 ning north and south. The entire north 

 end of the range is protected by the 

 boiler room and potting shed. All the 

 south gables are glass. House No. 1, 

 on the east, is the only separate or en- 

 tirely disconnected house; it is 18x145 

 and nine feet to the ridge; it has wooden 

 walls; it is used for chrysanthemums, 

 followed by sweet peas, and needs a 

 temperature of 50 degrees. House No. 



2 is 18x135 and ten feet to the ridge; 

 the east wall is wood; there is a glass 

 partition between it and the next house 

 to the west; it is used for roses, ^ith 

 a temperature of 60 degrees. Houses 



3 and 4 are not separated by a parti- 

 tion; they are each 30x145 and fourteen 

 feet to the ridge;, the west wlill is 

 wood; they are u^ed foj carnatiotis, 

 with a temperature of 50 degrees. 



Will a tubular boiler, 3x12 feet and 

 containing thirty-six 3-inch flues, heat 

 these houses? How large should the 

 grate be in such a boiler f Blouse No. 1 

 is now piped with a 3-inch flow and

 a 2-inch flow and six 1-inch returns, 

 but that is not enough and I expect to 

 repipe it with 3-inch tubes. I am plan-

 tubes; how many will be needed? The 

 lowest outside temperature here is 

 usually from 10 to 18 degrees, but some-

 boiler is in a pit and is tapped for 

 6-iuch pipe for the main flow and re-

 three feet below the lowest part of
