 is all that is required when galvanized 

 iron pipe is used. 



CAPACITY OF BOILER. 



I have three greenhouses, each 25x 

 75, seven feet high at the sides and 

 sixteen feet to the ridge, which I wish 

 to heat with steam. I have a marine 

 boiler, 2%xl0 feet, with a firebox and 

 forty flues. Will it be of suflScient 

 heating capacity for this plant, in this 

 Michigan climate? C. W. A. 



The question does not state how 

 much glass, if any, there is in the side 

 walls; nor does it give the temperature 

 desired. However, it may be said that 

 if there is no more than four feet of 

 glass in the side walls of the houses 

 and a temperature of 60 degrees will 

 answer, a boiler with a rating of twen- 

 ty horse-power should heat the houses. 

 The size of the flues is not given, but 

 if they are as large as 2-inch, the boiler 

 should be amply large for the present 

 plant. 



DIAMETEB OF BISEB. 



We wish to know whether a 2-inch 

 riser from the boiler would be large 

 enough to feed the following system: 

 We have three connecting houses, cov- 

 ering in all a space of 50x60 feet. The 

 riser is to run from the boiler to the 

 highest point and divide into three 

 2-inch flows, dropping from the boiler 

 to the end of the houses, a length of 

 fifty feet, and then returning in each 

 house in five 2-inch pipes. Our tem- 

 perature seldom drops to 20 degrees 

 above zero here in southern Louisiana, 

 and perhaps we have too many returns 

 for the space. A. F. C. 



Whether the number of return pipes 

 is excessive cannot be determined with- 

 out knowing what temperature is de- 

 sired in the house, and the size of the 

 riser will depend largely upon the num- 

 ber of returns. 



The best results in a house sixty feet 

 long, and in which there are fifteen 

 2-inch returns, cannot be secured with 

 anything less than a 3-inch riser, al- 

 though two 2^/l>-inch or three 2-inch 

 could be used instead. If a riser of 

 ample size is furnished and the tem- 

 perature desired is not greater than 60 

 degrees, it would be possible to heat the 

 houses using twelve 2-inch returns in 

 addition to three 2-inch flow pipes, 

 while, with a single 2-inch pipe as the 

 riser, the flow at best would be slow 

 and sluggish in the returns and little 

 heat would be furnished. 



What is the Most Vital Point 

 in Grate Construction? 



Grate makers and neers agree 

 that the moBt important point 

 is to keep the air spacea open 

 as long as possible under all 

 conditions. 



We guarantee to keep the 

 air spaces of the 



Martin Anfi-rrictlon 

 Rocking Grate 



open longer under any condi- 

 tions than can be done by any 

 other grate in existence. 

 The hottest fire you can build will not warp a "Martin," and it can be 

 installed without disturbing the brick work. 



We refer to Peter Reinberg, Emil Buettner, Bassett «fe Washburn, Wietor 

 Bros., Adam Zender, Sinner Bros., Albert Dickinson Co., and many others.

The Standard

Is acknowledged the best for the

 Its work without trouble and annoy-
