RADIATION. 



We wish to ascertain how best to heat 

 three rose houses, one 25xG0, the others 

 20x60. All are even span, with glass 

 sides and ends. We need 65 degrees in- 

 doors when the outside temperature is 

 20 below zero. The source of heat is a 

 ■fifty horse-power tubular boiler set about 

 a foot below tlio level of the return. It 

 is also used to heat- a house 20.\67, one 

 20x.'J0, one 20xlL'o and a dwelling and 

 office with about 125 feet of radiation in 

 each. The fuel is steam coal. What 

 size of pipe is best for radiation in all 

 the houses! W. F. C. 



The rose house, 25x60, will require 

 about 375 feet of radiation, equal to 

 862..') lineal feet of IVi-inch pipe when 

 the boiler is working under ten pounds' 

 pressure. Each of tho houses, 20x60 

 feet, will require 300 feet of radiation, 

 equal to 690 feet of 1%-inch pipe. The 

 house, 20x67 feet, will require 325 feet 

 of radiation, or about 750 feet of 1V4- 

 inch pipe, while the house. 20x50 feet, 

 requires 240 feet of radiation, or about 

 552 feet of IVi-incli pipe. The house 

 20x125 feet takes 600- feet of radia- 

 tion, or 1,380 lineal feet of IVi-iuch 

 pipe. In addition to the above each of 

 the houses should bo provided with a 2- 

 inch riser or supply pipe running from 

 the boiler to the far end of tho house, 

 then divide into coils under the benches 

 which shall contain not less than the 

 number of lineal feet of pipe specified 

 for each house. I .judge that one of the 

 chief difEcidtics with this plant lies in 

 the fact that the boiler is not far enough 

 below the level of the returns. If the 

 •returns can be raised or -the boiler low- 

 ered, results will be much better. If 

 neither of these is possible a steam trap 

 or siphon pump will overcome the dif- 

 «culty. L. C. C.
