The Florists^ Review 



April 13, 1918. 



feet. All of these houses are six feet 

 to the plates. 



One of the outer houses has two 

 feet of glass in the outside wall and 

 is to be heated to 55 degrees when the 

 outside temperature is 10 degrees be- 

 low zero. For this house we would use 

 one 2-inch overhead flow pipe and six 

 1^-inch or eight 1-ineh returns. For 

 the other 18-foot bouse, which has three 

 feet of glass, a temperature of 60 to 

 65 degrees is desired. One 2-inch flow 

 pipe and nine 1%-inch or twelve 1-inch 

 returns should be used. To give 55 

 degrees in the middle one of the three 

 houses, supposing it is twenty-fiA'e feet 

 wide, we would use one flow and eight 

 1%-inch or ten 1-inch returns. 



In the new section, which is on the 

 opposite side of, and twenty-five feet 

 away from, the boiler house, there are 

 three houses, each 25x100, with the 

 plates seven feet from the ground, and 

 the outside walls have four feet of ex- 

 posed glass. 



One of the outside houses is to be 

 heated to 50 degrees when 10 degrees 

 below zero. For this we would use 

 one 2-inch overhead flow and eight V/i- 

 inch or ten 1-inch pipes. In the mid- 

 dle house, for which the same tempera- 

 ture is desired, but which has no ex- 

 posed walls on the sides, use one flow 

 and six or seven 1%-inch returns or 

 nine 1-inch returns. In the other house, 

 which iias one wall exposed, and for 

 which the temperature should be 60 to 

 65 degrees, use two flows, one upon 

 each plate, and either eleven lJ4-inch 

 or fourteen 1-inch returns. 



Where there is but one flow pipe in 

 a house, it should be carried to the 

 farther end of the house and, at the 

 ends of the benches, should branch 

 each way and drop down a 1^-inch 

 pipe where needed to supply the coils, 

 which should be under the benches ex- 

 cept in the houses with exposed walls, 

 which should have two or three returns 

 on these walls. In the house with two 

 flows, all of the returns may be on the 

 walls, or all but three returns on the 

 outer wall may be under the benches. 



With a little care in firing, it should 

 be possible to heat all of the houses in 

 both ranges with a SS-horsepower 

 boiler, and a SO-horsepower boiler 

 would furnish a wide margin. For the 

 main flow to each of the ranges a 

 4-inch pipe will answer. 



POSITION or ORATE BARS. 



In a horizontal tubular boiler, 6x18 

 feet in size, what should be the distance 

 from the grate bars to the shell of the 

 boiler, in order to obtain the best re- 

 sults in firing? We have been told 

 that thirty inches is about right, while 

 others advocate forty inches. 



G. V. B. & B.— Mich. 



For a boiler of the size mentioned, 

 the distance between the grate bars 

 and the shell of the boiler may vary 

 from thirty-two to thirty-six inches. 

 We would use the greater distance 

 where the grate bars are sftiort and the 

 grate area consequently is small, but 

 we would allow less space where the 

 grate bars afford a large grate area. 

 On the whole, we prefer the latter ar- 

 rangement, as this is adapted to a 

 'thin fire.
