Greenhouse Heating. 



TWO MISSISSIPPI HOUSES. 



We have just built another carnation 

 house, 30x80, and should like to know 

 what amount of piping will be needed 

 to keep it at 55 degrees, with the out- 

 side temperature 10 degrees above zero. 

 Please let us know, also, how many 2- 

 inch returns a 214-inch flow will carry. 

 We have 2-inch and 2i/4-inch pipe on 

 liand and also some 3-inch, and should 

 like to use it if possible. Also let us 

 know the amount of piping required 

 for a house 29x54, under the same con- 

 ditions. D. F. C. 



The number of returns of the size 

 mentioned which can be supplied by 

 2-inch and 2i^-inch flow pipes will de- 

 pend to a considerable extent upon the 

 length of the house. In an average 

 house a 2-inch flow will supply 200 

 square feet of radiating surface, but 

 if the coils are short 150 square feet 

 would be a maximum. A 2%-inch 

 flow pipe would handle 100 per cent 

 more radiation and a 3-inch flow would 

 handle three times as much as a 2- 

 inch flow. 



For a house 30x80 feet, to obtain a 

 temperature of 55 degrees in weather 

 10 degrees above zero, either two 3- 

 inch, throe 2i^-inch or four 2-inch flow 

 pipes, with nine 2-inch returns, should 

 be used. The same arrangement could 

 be used in the house 29x54 feet. 



A FEW HEATING PROBLEMS. 



I have a few heating problems upon 

 which I should like some advice. Our 

 plant is steam heated. One boiler has 

 already been installed, with a steam 

 trap system for returning the conden- 

 sation. I wish to install another boil- 

 er, for use in extremely cold weather, 

 or in case of disability of the one now 

 in use. The boilers will be set side by 

 side. The steam trap, I suppose, must 

 be set in such a position that I can 

 serve whichever boiler I am working, 

 and I expect to use valves on steam 

 outlets between the boilers and steam 

 main, to cut out whichever boiler may 

 not be in use. 



In case the boilers are both in use 

 and are both open to the same steam 

 main, will the steam trap serve them 

 both at the same time, so that the 

 proper water level will be maintained 

 in each boiler, especially if they are 

 not connected at the blow-off? Or 

 should they be joined together at the 

 blow-off, so that when working to- 

 gether an equilibrium will be main- 

 tained by the connections at both

steam outlets and blow-oflf? In that 

 case will it be advisable to connect the 

 steam trap outlet, or return, to the 

 blow-off, so that it can send the con- 

 densation to the boiler in that way? 



In using a steam trap for returninjj 

 the condensation to the boiler, is it not 

 all right to let this returned condensa- 

 tion come back to the boiler through 

 the blow-off opening? If not, where 

 is the best place? For a boiler fifty- 

 six inches in diameter by twelve feet 

 long, is a li/^-inch opening large enough 

 for the blow-off? The boiler I con- 

 template installing has this size of 

 opening, and it is in the rear head, as 

 close as possible to the bottom shell. 

 I had thought it should be larger, and 

 should be in the bottom of the boiler, 

 about six inches from the rear end — 

 about two and one-half or three inches

in size. In that case, which would be 

 the better, a reinforcing plate riveted 

 to the inside of the boiler, or a flange 

 connection riveted to the outside of 

 the shell, into which the blow-off pipe 

 would be screwed? W. H. C. & C. 



One steam trap will answer for sev- 

 eral boilers, no matter how or where 

 they are connected. In most boilers 

 the only provision for returning the 

 condensed water is through the blow- 

 off outlet. 



An outlet one and one-half inches in 

 diameter is large enough for a boiler 

 of the size described. It is customary 

 to have it in the bottom of the boiler, 

 near the rear end, but it could be in 

 the rear end; the only objection to this
