Igreenhonse Heating. 



BBICK-SET OR FIRE-BOX? 



"Which is the more economical boiler 

 to use, a bricked-in return tubular or a 

 fire-box return tubular? 



W. W. M.— Colo. 



More depends upon the proper ad- 

 justment of the grate and heating areas 

 than upon whether a brick-set or fire-box 

 boiler is used. Ordinarily brick-set 

 boilers are used for anything above 

 twenty-five horsepower and we would 

 have little preference down to fifteen 

 horsepower, below which we would use 

 a fire-box boiler. 



TEMPERATURE IS IN DOUBT. 



I have built a new greenhouse and 

 should like to have you advise me about 

 the heating. The house is 20x50 and 

 the rafters have a 32-degree pitch. 

 There are two feet of glass in one side 

 and the gal)le ends are glass. How 

 much piping will be needed to heat the 

 house to a temperature of 50 to 60 de- 

 grees in zero weather? How large a 

 boiler will be required? R. B. R. — Me. 



It will make considerable difference 

 in the size of the boiler, as well as in 

 the amount of radiation needed, 

 whether the plants to be grown in 

 the house will require 60 degrees in 

 the coldest nights, or whether it will 

 be safe to allow the temperature to drop 

 to 50 degrees in the coldest weather, 

 maintaining 60 degrees only in average 

 winter weather. 



For the former conditions we would 

 suggest the use of three 2%-inch flow 

 pipes and ten 2-inch' returns. If 50 de- 

 grees will answer in extremely cold 

 weather, we would use three 2-inch flow 

 pipes and either eight 2-inch or ten 

 l^^-inch returns. Two of the flows 

 should be on the plates and the other 

 about two feet below the ridge. With 

 ten returns we would place three on 

 each wall, or under the side benches.

and the other four under the middle 

 bench, connecting these four with the 

 flow pipe overhead. If eight returns 

 are used, two may be on the wall which 

 has no glass and the others on the other 

 side wall and under the middle bench. 



In case the house has solid beds, we 

 would use a 21/2-inch flow upon each 

 wall, with eleven 2-inch returns for 60 

 degrees and nine for 50 degrees, in two 

 coils, placing the odd return on the 

 side with glass. Run the flow pipes as 

 well as the returns downliill, and con- 

 nect the highest point of each flow pipe 

 with the expansion tank. 



For a temperature of 60 degrees we 

 would use a hot water boiler rated for 

 600 square feet of radiation, and one 

 with a rating of 500 square feet for 50 

 degrees. 



TROUBLE WITH A STEAM TRAP. 



We have installed a steam trap. The 

 water inlet and outlet of the trap are 

 made for IVj-inch pipe connections and 

 the steam inlet of the trap is a 1^-inch 

 opening. The inlet and outlet of water 

 and the inlet of steam have all been 

 reduced to 1-inch pipe. Is that any 

 reason why the trap does not work? 

 The trap is situated on the side of the 

 boiler, just above the water level in 

 the boiler. A receiver of the condensa- 

 tion is placed on the same side of the

 tem, and protected by check valves to 

 keep away boiler pressure. The gra^ ity 

 is sufficient; otherwise the system would 

 not drain so perfectly as it does. Th'.^re 

 is a fall of at least eighteen inches be-

 and the receiver from which the trap 

 is fed. I am enclosing a sketch. 



M. B. S.— Ky. 



The capacity of the trap has been re- 

 duced by the use of the smaller pii^'S. 

 Yet, if the trap is large enough to 1 i"' 

 die the water through 1-inch pipes, ^'^ 

 do not see why it will not work satis! aC' 

 torily, provided a steam pressure of i'^'^ 

 pounds or more is carried. Care shoulo 

 be taken that all parts are properly ail-
