RETURNING CONDENSATION. 



We are heating our five greenhouses, 

 each 200 feet long, by steam pipes as 

 follows: Three houses with a 2^-inch 

 supply and ten 1-inch returns. Two 

 houses with ten 1^4 -inch pipes but no 

 overhead supply pipe, the 1^-inch pipes 

 taking steam from the boiler and nin- 

 iiing under the benches to the farther 

 end of the houses and condensation re- 

 turning to the boiler through a 2%-inch 

 pipe. We have, in other words, 600 feet 

 of 2% -inch feed pipe, 6,000 feet of 1- 

 inch pipe, 4,000 feet of 1 14-inch pipe 

 and 200 feet of 2%-inch drip or return 

 pipe. We desire to ascertain the maxi- 

 mum condensation when the boilers are 

 working their best, say during a night 

 when the temperature is 20 degrees below 

 zero and every pipe carrying steam. We 

 are anxious to determine the kind and 

 number of pumps to return this conden- 

 sation to the boilers and should have 

 figures for the maximum condensation 

 per hour. H. H. N. 



Under normal conditions, with a house 

 temperature of 60 degrees, the pipe 

 mentioned should give about 170 gallons 

 of water per hour. The pump needed 

 will therefore be one of comparatively 

 small size. If the pump is to be worked 

 by the boiler pressure on the heating 

 boilers it will be necessary to secure a 

 pump with a large steam cylinder and a 

 small pump cylinder in order that suf- 

 ficient power may be secured to force a 

 small jet of water into the boilers 

 against the boiler or working pressure. 

 There are, however, pumps made to meet 

 this condition and pump makers can 

 give you a pump of the proper dimen- 

 sions if they know boiler pressure, quan- 

 tity of water to be elevated and the dist- 

 ance it has to be lifted. There are also 

 automatic return traps which are used 

 satisfactorily for this purpose in many 

 greenhouse establishments.
