THE SUPERIOR 



Improved Internal-Fired Steel Boiler 



Made in 10 sizes, to heat from 2O0O to 6500 feet of 4-inch 

 pipe. No brick-work necessary; shipped on skids, all 

 ready to move into place and begin firing. Can be cleaned 

 without letting the fire out. All hubs made so they 

 can be used for either cast-iron or steam pipe. Tested 

 at 25 lbs. pressure and warranted; can be used for low 

 pressure steam by adding steam drum. Best material; 

 best workmanship. Specially designed for greenhouse 

 use; corrects the faults of other boilers. Lightest boiler 

 on the market capable of performing equal work. We 

 defy competition in prices on any boiler of equal 

 capacity. Investigate. Send for new illustrated cata- 

 logue, just out. "■

should be provided with a 3rinch flow 

 and thirteen 2-inch returns, and the^ 

 house 15x75 should have a 2V^-inch flow 

 and eleven 2-inch returns. A single 

 4-ineh flow from the boiler through the 

 shed should be large enough to serve 

 these three houses. L. C. C. 



PIPING IN OHIO. 



I am building a greenhouse 32x60 feet, 

 with walls five feet high and the ridge 

 thirteen f^et from the floor. How much 

 radiation do I need for heating with 

 steam? H. A. C. 



To carry a temperature of 60 to 65 

 degrees witli low pressure steam you will 

 require twenty lines of l^^.-inch pipe as 

 returns, supplied by a 2%-inch riser un- 

 der the ridge. L. C. C. 



HEAT FOR A LETTUCE FRAME. 



I wish to heat a lettuce frame 6x70 

 feet, on the south side of a house heated 

 by a flue. Can this be done with a pipe 

 coil in the furnace, made with l^^-inch 

 pipe and return bends t ,How many re- 

 turns wonld the frame require, with the 

 flow in the house? W. S. 



The lettuce frame 6x70 feet will re- 

 quire eighty feet of radiation, which 

 can be supplied by three lines of 1'^,- 

 inch pipe the length of the bed. If 

 a li/^rincfi'flow is carried from a coil 

 made up of twenty-five lineal feet of 

 1%,-inch pipe in the furnace, to the far 

 end of the greenhouse and there enters 

 the frame, to return by three l^^-inch 

 returns, you should be able to get a 

 satisfactory temperature. L. C. C. 



HEAT FOR CARNATION HOUSE. 



I have a nineteen horse-power steam 

 boiler, used four years. Can I have it 

 tapped with 2i^rinch holes and use it 

 for hot water? It is an upright boiler, 

 with a solid grate three feet across and 

 a space of. two feet between the grate 

 and the ^bcs. Can I burn hard coal 

 with good results? 



Wi^ this boiler I wish to heat a car- 

 nation bouse 20x100 feet, and twelve

feet to the ridge. The house runs east 

 and west. The back wall is six feet high 

 and the front wall five feet high, with 

 three feet of glass in the front. In this 

 Massachusetts climate, how much pipe 

 would be required to heat with hot water! 

 Or, could I use the boiler just as it is for 

 steam, and could I burn hard coal as I 

 would in hot water heating? I have 800 

 feet of 1-inch pipe. I should prefer to 

 use hard coal. W. T. W. 



You can use the boiler as it is with 

 hard coal for low pressure steam, and by 

 equipping it with an automatic dia- 

 phragm to open and close dampers, it 

 should give satisfaction. If you wish 

 to use it for hot water, I would ad- 

 vise having the shell reamed for a 2^^- 

 inch or 3-inch flange, to be bolted on. 



If you use steam, a 2-inch flow under 

 the ridge, with twelve 1^,-inch returns, 

 should give good results. If you use hot 

 water, use a 3-inch main flow under' the 

 ridge and twelve 2-inch returns. Yon 



might make a compromise by using the 

 first described equipment during mild 

 weather for hot water, and during severe 

 weather as a steam plant. L. C. C. 



HEATING FOR SALESROOM. 



I am putting up a salesroom 23x23 

 feet. The side walls will be of wood and 

 five feet high ; the roof will be of glass ; 

 the ridge will be eleven feet from the 

 floor. I have a No. 16 Hitchings hot 

 water boiler, with outlets for 4-inch 

 pipe. Could I use this boiler by making 

 the fire box smaller with fire bricks, and 

 could I pipe this house without digging 

 a boiler pit? I wish to pipe against 

 the walls. I want to use the building 

 to grow a few of my bedding plants, 

 as well as for a salesroom. Kindly give 

 me suggestions on piping. S. S. S. 



You can, of course, reduce the size 

 of the fire box as you suggest, with fire 

 brick, but by so doing you will lose
