Greenhouse Heating. 



WHEN BOILER IS TOO LABQE. 



My experience with a large boiler 

 may be of benefit to L. C. B., whose 

 inquiry appeared on page 90 of The 

 Review of March 2. We have about 

 8,000 feet of glass and started with a 

 small boiler. Later we added a tubular 

 boiler, 5x16 feet, containing eighty-four 

 3-inch tubes. We kept the small one for 

 fall and spring use. After one season 

 we threw out the small one, finding 

 that it consumed more coal than the 

 larger one in doing the same work. 



We accomplish this by cutting down 

 the firebox space and by shutting off 

 the chimney draft. The back half of 

 the grates is covered by a cast-iron 

 plate, obtained at a junk shop. This 

 'prevents the air from entering. Then a 

 thin, clean fire is kept in front, using 

 one or both doors, as the season de- 

 mands. When only one door is used 

 the other side is filled with ashes to 

 keep-^ir out. Should we ever need more 

 steam the plates can be easily re- 

 moved. The chimney draft is closed to 

 about an 8-inch hole. The result is per- 

 fect and we use less coal to the foot 

 of radiation than any of our neighbors. 



G. S. Eamsburg. 



One of my neighbors, like L. C. B., 

 has a boiler that is unnecessarily large, 

 but he succeeded in running it econom- 

 ically by adopting the following plan: 

 It is a horizontal boiler and he plugged 

 up the top row of flues with wooden 

 plugs, so that the fire could not pass 

 through them. Then he could make 

 steam much more easily, with a smaller 

 amount of water, and the boiler would 

 hold steam a longer time. Another plan 

 might be to make the firebox smaller 

 by placing bricks on each side.

BOILER PROBABLY TOO SMALL. 



We are having some trouble in keep- 

 ing up the temperature in our houses. 

 We have four greenhouses, each 16x118 

 and nine feet to the ridge, which we 

 are heating with a Winchester hot 

 water boiler. No. 34. It is an upright 

 boiler and has a firebox thirty-six 

 inches in diameter. There are two 4- 

 inch mains from the boiler along the 

 shed, with one 3-inch flow which runs 

 to the far end of each greenhouse and 

 then drops down under the benches, 

 where it connects with six 2-inch re- 

 turns running back to a 4-inch main 

 return in the shed. The highest point 

 is eight feet directly above the boiler.

No loss from suddon drops in 

 temperature if you use the 



Hughson Regulating Valve 



In connection with a steam heating plant. Carrr 40 or 

 50 pounds pressure on the boiler and set the valve for 6 

 or 10 pounds— it will do the rest. You'll be free from 

 worry this winter, if you follow this advice: " Install a 

 Hucbson RegruIallnB Valve when making your 

 repairs." Ask for our Catalogue, which also shows 

 Steam Traps and other devices.

The temperature often falls to 40 de- 

 grees by morning, after being left at 

 53 degrees at eleven o'clock at night. 

 We want to maintain a temperature of 

 about 50 to 55 degrees. Our coldest 

 weather here, in eastern Virginia, is 

 rarely lower than 15 degrees above 

 zero. What is the trouble? Have we 

 too much of a load on our boiler, or 

 have we not enough returns? 



B. H. P. C. 



It is extremely difficult to give an 

 offhand opinion regarding the trouble 

 mentioned. It would seem, however, 

 that the amount of radiation is ample 

 to maintain the temperature desired. 

 The trouble would, therefore, appear to 

 be due either to lack of boiler capacity 

 or to some defect in the arrangement

 mined from the description, the piping 

 should give a free circulation, and the 

 trouble, then, would appear to be with 

 the boiler. 



I have had no experience with the 

 Winchester heater, but it is probable 

 that the size you have in use, unless it 

 is unusually effective, would be capable 

 of heating not to exceed 2,000 square 

 feet of radiating surface, while a boiler
