The Fbrists^ Review 



Sbftbmbbb 11, 1010. 



It is always desirable to have the top 

 of the boiler below the lowest portion 

 of the returns and considerably more 

 than this will improve the circulation. 

 On the other hand, if this cannot be se- 

 cured, a fairly satisfactory circulation 

 may be obtained, when the flow pipes are 

 run overhead, if the grate is two feet 

 below the returns. 



When using wood in a hot water 

 boiler it is always well to have a long 

 and rather narrow fire pot, in order that 

 wood three feet in length may be used. 



SAFE PAINT FOB PIPES. 



Which is the best paint to use on hot 

 water pipes to preserve them and at the 

 same time to be safe from injuring 

 greenhouse plants f Would graphite or 

 asbestos paint be injurious to plantsf 



Bro. Leo. — Ala. 



In selecting a paint for use on green- 

 bouse heating pipes, benches, etc., care 

 should be taken not to use any brand 

 in which coal tar in any of its forms is 

 found. For the purpose named any 

 quick-drying forms of mineral or barn 

 paints may be selected. We do not 

 know of any which cannot be used with 

 safety, but the above fact should be 

 kept in mind. 



Badiation from the surface of the 

 pipes will be favored if the paint does 

 not form a glaze, as a rough surface 

 radiates more heat than a smooth one. 



EAISE MAIN FLOW PIPE. 



I am having trouble with my north 

 house. The range is gravity fall from 

 north to south for about eight feet. I 

 use 2-inch pipes for flows and 1%-inch 

 pipes for returns. There are twelve 

 pipes running each way and it seems 

 as though the water caused by con- 

 densed steam from the main goes up to 

 the north end and has to be forced out 

 through the 2-inch flow pipes, which 

 are eight feet above the main pipe. 

 The main pipe lies on the ground. Would 

 it be best to raise the 5-inch main pipe 

 about six feet and then take the 2-inch 

 flow pipe direct from the main pipef 



E. L. I.— Mo. 



From the above statement we infer 

 that the reason for the trouble has been 

 found and judge that it may be cor- 

 rected by connecting the end of the 

 main flow with the end of the main re- 

 turn. We would also favor raising the 

 main flow pipe seven or eight feet and 

 at the same time giving it a slight 

 fall, thus favoring the flow of the con- 

 densed steam and its return to the 

 boiler. If this is done, we think that 

 the by-pass need not be larger than one 

 inch. In case the slope of the land 

 makes it impossible to give a fall to the 

 main flow pipe, we would at any rate 

 elevate it as suggested and connect the 

 end with the return. 



TO HEAT OKLAHOMA HOUSE. 



We are submitting a heating problem 

 for a greenhouse to be erected. The 

 house will be in two sections, each 21x 

 80. One half will be devoted to flowers 

 and the other half to vegetables. There 

 will be 3,840 feet of glass in the roof. 

 The side walls will be four feet of glass 

 and three feet of wood wall, forty feet 

 from the front. The other forty feet of 

 the greenhouse will be six feet of glass 

 and two feet of wood. The north wall 

 and gables will be all wood. This house
