THE SUPERIOR 



Improved Internal-Fired Steel Boiler 



Made in 10 sizes, to heat from 2000 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 



Eressure steam by adding steam drum. Best material; 

 est 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.

middle bench, and five 2-inch pipes un- 

 der each outside bench. Place valves 

 on each end of each of two pipes under 

 the outside benches, so as to cut out the 

 circulation on mild days. Connect the 

 expansion tank with the main return near 

 the boiler by %-inch pipe. Use a large 

 tank and place it twelve feet or more 

 above the highest point in the system.

PIPING IN SOUTHERN ONTARIO. 



I have built an addition to my green- 

 houses and have installed a steam heat- 

 ing system, but we are not satisfied with 

 the way it works. We can get steam 

 up to twenty pounds or more, but as soon 

 as it is turned on, the system runs down 

 to nothing and we cannot raise it. 



I have a return flue boiler, nine feet 

 six inches long, with thirty-six 3-inch 

 flues. It is fitted with the improved 

 shaking grates, and the grate surface is 

 two feet six inches by three feet six 

 inches. This is intended for the heating 

 of two parallel, connected houses, 21x100 

 and 18x100. The steam is taken from 

 the dome of the boiler through a 2-inch 

 pipe and carried ten feet to the end 

 of the greenhouses, where there is a cross- 

 head with a IV^-inch flow leading across 

 to the larger house, and connecting, by 

 means of 1 14 -inch pipe, with four coils 

 of 1^4 -inch pipe, three pipes in a coil, 

 running the full length of the house. 

 The other flow on the cross-head is 1%- 



inch pipe, and conveys steam to three 

 coils of 114 -inch pipe, three pipes in a 

 coil, for the smaller house. The boiler 

 is in a pit, walled in on both sides. 

 The return pipe is 2-inch. There is a 

 fall of two feet six inches from the coil 

 to the water line of the boiler, which 

 makes a fall of four feet six inches from 

 where the steam enters the coil to where 

 the water enters the boiler. The coils 

 all have a fall of one inch in twenty 

 feet. 



Have I pipe enough to heat in zero 

 weather? What can I do to make a bet- 

 ter circulation? Would it be better to 

 change to a water system, and if so, 

 would 2-ineh pipe do to convey the flow 

 under the ridge? How many coils of 

 114 -inch pipe, three in a coil, would be 

 required in each house, to heat to 65 

 (legrees in zero weather? H. E. E. 



The system of piping seems to be quite 

 complete. The changes I would suggest 

 are as follows: Place a 2 %-inch riser 

 under the ridge of each house; carry 

 each direct from the boiler to the far 

 end of the house; there divide by 2- 

 inch pipes to feed as many coils of 114- 

 inch pipe as there are benches in the 

 house, using twelve pipes in the 18-foot 

 house and fifteen in the 21-foot house. 

 Keep the coils as close to the bottom 

 of the benches as possible, so as to in- 

 crease the height from the water level 

 of the boiler to the radiating pipes as

much as possible. Place a swing check 

 valve in the main return near the boiler 

 and use plenty of air valves on the heat- 

 ing pipes in the coils. Your chief lack 

 is in radiation and in distance from the 

 water level of the boiler to the radiating 

 pipes. L. C. C.
