Tie Florists' Review 



Mabch 4, 1915. 



benches, according to the arrangement 

 of the house. The pipes that make up 

 the other coil may be distributed under 

 the middle bench. 



Connect the expansion tank with the 

 highest part of the system, which should 

 be arranged with the flow pipes running 

 downhill, making connection with each 

 of the flow pipes unless they start as 

 one main flow. The expansion tank 

 should be located two feet above the 

 highest part of the system. The mains 

 should be used as radiating surface. 



TAEDY EETXTEN OF WATER. 



I have a new range of four houses. 

 Two of them are each 35x300, one is 

 22x200 and one is 9x100. The boilers, 

 which are sectional, are located at the 

 southeast corner and the water line is 

 thirty inches below the surface at the 

 end of the return. My steam fitter in- 

 sisted on a "wet" return and placed 

 it so that the highest point of the re- 

 turn is six inches below the water line 

 in the boilers. The main steam line is 

 6-inch and it extends through the work- 

 room, sixty -five feet; next through the 

 22-foot house a distance of fifty feet; 

 then at an angle across the 22-foot 

 house and across one 35-foot house, 

 terminating three feet inside the sec- 

 ond 35-foot house. It drains from the 

 boiler and is reduced to 3-inch and 

 dropped directly into the return at a 

 point thirty feet from the end of the 

 return. The 3-ineh coupling line be- 

 tween the end of the main and the re- 

 turn is always open. Should it have a 

 valve of some sort? The return is ex- 

 tremely tardy and I intend to install 

 a Morehead return trap. Would it be 

 advisable to raise the return? 



When we fire up and raise five or six 

 pounds of steam, the water spouts about 

 two feet high out of the air valves 

 before the check valves act. It occurs 

 to me that the pressure of direct steam 

 via the 3 -inch connecting pipe is re- 

 tarding the discharge of condensation 

 through the checks, and that 155 feet 

 of 3-inch pipe filled with water allows 

 the water to be cooled too much before 

 being again converted into steam. 



F. W. A. — Ohio. 



It is dil3^ult to determine, from the 

 description and sketches furnished, just 

 how the flow pipes are arranged or 

 where they connect with the coils. It 

 appears that there is a 3-inch connec- 

 tion between the main flow and the re- 

 turn. This, I infer, is nothing more 

 than a drip pipe. A considerably small- 

 er pipe would answer for this purpose 

 and I would either put in a smaller 

 pipe or a valve by which the size 

 may be reduced. This will be particu- 

 larly necessary with a "wet" return. 



My suggestion is, however, that the 

 return be raised so that it will drain 

 back to the boiler. I would give the 

 return a fall of one inch in twenty 

 feet, and keep it two feet above water 

 level until it reaches the boiler room. 

 If this can be done, good results can 

 be obtained with a gravity system, but 

 unless the upper end of the return is 

 three feet above the water level I pre- 

 fer to use either a steam trap, or an au- 

 tomatic pump, worked preferably by 

 electricity, for returning the water. 



Des Plaines, HI. — In order to keep 

 the foundry running, the Garland Mfg. 

 Co. is turning out sash weights by 

 the ton. Some kindred lines may be 

 taken up in the near future.
