 to use this pipe, a generator should be 

 installed. In any case, run all the pipes 

 downhill and make sure that all the 

 pipes are free from air pockets. 



BEDUOINa VAIjVE. 



I have a return tubular boiler twelve 

 feet long and four feet wide, with 

 thirty-nine 3%-inch flues. Please tell 

 me the right size of fire box for it. I 

 seem to be burning too much coal for 

 that size of boiler. I am heating two 

 houses 25x125 and five other houses, 

 25x117, 24x110, 20x75, 8x125 and 6x50, 

 respectively. Steam heat is used, with 

 a Morehead trap. I average about fif* 

 teen pounds of steam pressure, although 

 the state inspector allows me twenty- 

 five pounds. Would there be any advan- 

 tage in using a reducing valve f If I 

 have twenty-five pounds of pressure 

 without a reducing valve, would I have 

 any change in temperature in the green- 

 houses if I installed a reducing valve 

 and set it at ten pounds t 



A. P. 0.— O. 



The temperature desired in the houses 

 is not stated, nor is the amount of glass, 

 if any, in the side walla. For an aver- 

 age temperature of 60 degrees in zero 

 weather, 2,800 square feet of steam 

 radiation, with ten pounds' pressure, 

 ahould be sufficient for the houses men- 

 tioned, provided there is no glass in the 

 side walls. A proportional increase in 

 the amount of radiation should be made 

 for any glass except in the roofs and 

 one end of the houses. 



Judging from the dimensions given, 

 the boiler would be rated for about 

 forty-five horsepower. Although some- 

 what larger than is really needed, it is 

 not excessively large for the econom- 

 ical operation of the Tieating system. 

 A grate three and one-half feet square, 

 or with twelve and a quarter square 

 feet, would answer for the amount of 

 radiation with steam lump coal, but for 

 run-of-mine fourteen to sixteen square 

 feet of grate surface would be prefer- 

 able. 



It would not be well to earry more 

 than ten pounds' pressure at the boiler 

 for a range of the size mentioned. The 

 use of a reducing valve is only to be 

 recommended for a large range of long 

 houses. It makes it possible to use 

 smaller mains. In a given range a 

 higher temperature can be maintained 

 with a pressure of twenty-five pounds 

 without a reducing valve than when 

 there is a reducing valve set at tea 

 pounds, but more coal will be required.
