The Florists^ Review 



July 12, 1917. 



would not supply more than 250 square 

 feet of radiation, unless a considerable 

 amount of pii)ing is placed upon the 

 end walls. We would prefer to use 

 three 2-inch flow pipes, placing one on 

 each plate and the other two feet below 

 the ridge. Unless the house is consid- 

 erably exposed, we would only use four 

 2-incli pipes in each of the wall coils, 

 and four others distributed under the 

 middle bench and connected with the 

 overhead flow pipe. 



COAL OR FUEL OIL— WHICH? 



I am using a Johnston steam boiler, 

 with a grate surface 30x38 inches and 

 a rating of 2,275 square feet. Last 

 winter I burned sixty-four long tons of 

 New River bituminous coal in heating 

 two houses, with an area of 10,000 

 square feet of glass, to a carnation 

 temperature, in northern Massachusetts. 

 I should like to get a little information 

 concerning the approximate quantity of 

 fuel oil that would be necessary to heat 

 the same houses. I have a tank with a 

 capacity of 2,500 gallons, which I can 

 use for storage purposes. What appa- 

 ratus would I need? J. E. S. — Mass. 



The comparative economy in using 

 coal and fuel oil for heating purposes 

 will depend largely, of course, upon the 

 quality and cost of these fuels. As a 

 rule, we may consider that a good grade 

 of coal furnishes 14,000 heat units and 

 there would perhaps be 19,000 units in 

 fuel oil per pound, or, in other words, 

 the oil is worth about one-third more 

 per pound than coal. This, of course, 

 does not begin to equal the difference 

 in cost, but there will be a large saving 

 in the cost of firing, removing ashes, 

 etc., if oil is used as the fuel. 



Aside from the necessary piping and 

 a special burner for the oil, a steam jet 

 to spray the oil must be provided. 



THE PIPING AND THE STACK. 



Kindly toll me how to arrange the 

 piping in my three greenliouses, as the 

 present arrangement is not satisfactory. 

 One of tlio liouses is 17x150; the other 

 two are each 14x150. They are con- 

 nected, witli no walls between. The 

 side walls are seven feet high and con- 

 tain three feet of glass. The houses 

 run east and west and the west gable 

 end is exposed. The boiler, a No. 5 

 Kroeschell, is in a shed at the east end 

 and is below tlie level of tlie green- 

 house floors. I wish to maintain a 

 temperature of 55 to 60 degrees. Here, 

 in nortliern Indiana, the outside tem- 

 perature may droj) as low as 12 degrees 

 below zero. I have a considerable quan- 

 tity of 1-inch, li/^-inch and 2-inch pipe 

 which I should like to use. I also have 

 a 4-inch pipe which might be used for 

 one flow the length of the house. 



What size of chimney should I erect? 

 I intend to build it of brick. In stating 

 its width, please give both inside and 

 outside measurements. F. W. — Ind. 



To heat the house 17x150, which, as 

 we understand, has three feet of glass 

 in one wall, to a temperature of 55 to 

 60 degrees when the outside tempera- 

 ture is 12 degrees below zero, we would 

 place the 4-inch flow on the outer wall 

 and also use two 2i/i-inch flows, placing 

 one of them on tlie other ])Iate and tlie 

 second under the ridge. Eight 2-inch 

 returns will be required. Three should 

 be connected with the 4-inch flow, three
