Greenhouse Heating. 



OIL AS FUEL. 



Can good results l:e obtained by the 

 use of distillate as fuel with a sectional 

 water boiler? What apparatus is neces- 

 sary to use it and how expensive is it? 

 Can crude oil be used as fuel without 

 steam? If so, how? What appliances 

 would be necessary and what would 

 be the cost? H. A. N. 



In most sections distillate will be 

 found rather more expensive than coal 

 for greenhouse heating. In the case 

 of crude oil the only safe way is to 

 have at least one boiler in which steam 

 is used. Though there are burners in 

 which steam pressure is not used, these 

 are less reliable and not as satisfactory 

 as when steam pressure is available for 

 spraying the oil. There are a number 

 of forms of burners on the market an1l 

 it will be well to obtain specifications 

 and prices from the manufacturers. 



ABEA OF BADLATINQ SUBFACE. 



Will you please teil me the rating of 

 the No. 4 Furman boiler? Please state, 

 also, the number of square feet of 

 radiating surface in the following pip- 

 ing: Seventy feet of 3 1/4 -inch, fifty 

 teet of 2- inch, 200 feet of 2 1/2 -inch, 

 and 1.000 feet of l^/.-inch returns. 



E. L. 



We do not have a copy of the Fur- 

 man boiler catalogue at hand and do 

 not remember the exact rating of the 

 different sizes. Our experience with 

 snveral of the Furman boilers would 

 indicate that they are well up to the 

 rating of the manufacturers. The 

 200 feet of 214-inch pipe will give 

 about 150 square feet of radiating sur- 

 face; 1,000 feet of l^^-inch, about 500 

 square feet, and the seventy feet of 

 3^-inch and fifty feet of 2-inch about 

 120 square feet more, or a total of 770 

 square feet. 



PIPING IN BHODE ISLAND. 



I should like to have your heating ex- 

 pert tell me the amount of lV4inch 

 pipe that will be required to heat a 

 house 14x65 feet. Please state the size 

 of the flow and return pipes acd the 

 best way to arrange them. I have a 

 vertical boiler, seven feet high and 

 thirty inches in diameter, with a firo- 

 pot twenty-four inches in diameter. 

 Will this boiler heat the house de- 

 scribed and a smaller one, 16x24 and 

 ten feet to the ridge, with two feet of 

 glass in the sides and in both ends? 

 The 65-foot house measures ten feet to 

 the ridge; it has glass in both ends and 

 two feet of glass in the sides. The 

 side walls are all four feet high. I 

 want a carnation temperature.

are all satisfied with the results it has given, Knd many 

 duplicate < rders is the proof. This Valve will main- 

 tain a steady pressure on tne low side, no matter 

 how the iniiial pressure fluctuates. By carrying 40 or 60 

 Pounds pressure on the boiler and setting the valve to 

 carry 5 or 10 pounds on the line, you always have a
