Mentaoii The Keview wben you write 



of the house and connecting it with 

 eight 2-inch returns, which can be car- 

 ried either on the walls or under the 

 benches, or both. A boiler rated for 300 

 square feet of radiation, and with a 

 grate twenty inches in diameter, should 

 heat the house easily. 



FEED PUMP AND BECEIVEB. 



Please have your heating expert give 

 me some information with reference to 

 the kind of steam pump and receiver 

 for the circulation of steam and for re- 

 ceiving the condensation which is re- 

 turned to the boiler. What size of 

 apparatus would be sufficient for 25,000 

 square feet of glass? The engineer who 

 installed the boiler stated that the re- 

 ceiver of the pump should be three feet 

 below the level of the pump. Please 

 give me full information about the kind 

 of pump, the size, installation, etc. 



M. L. 



The temperature at which the houses 

 are to be kept is not given; neither is 

 the pressure to be maintained in the 

 system stated. Both of these considera- 

 tions would have much to do with the 

 size and kind of pump to be used. It is 

 probable that the range described can 

 be heated by means of 5,000 square feet 

 of radiating surface, and if a steam 

 pressure of five or six pounds is main- 

 tained a duplex boiler feed pump rated 

 as 3-2-4 would be of sufficient capacity 

 to return the water to the boiler. This 

 would have a steam cylinder three 

 inches in diameter; the water cylinder 

 would have a diameter of two inches, 

 and the length of the stroke would be 

 four inches. A 4-2%-6 single cylinder 

 pump could also be used, or an electric 

 pump might be installed. 



The reservoir to receive the water 

 from the coils should be lov/ enough 

 so that they would drain by gravity. 

 A steel tank holding five barrels will 

 answer for a heating plant of this size, 

 which will evaporate 100 to 120 gallons 

 of water per hour. 



For an up-to-date arrangement a self- 

 contained automatic pump and receiver 

 should be used. With the automatic 

 feed a comparatively small receiver 

 will answer; a capacity of twenty to 

 twenty-five gallons will be sufficient. 

 Whether self-contained or not, the re- 

 ceiver should be on a level with, or 

 above the pump, as hot water cannot 

 be lifted by suction. While most of 

 the self-contained pumps have the res- 

 ervoirs from one to two feet above the 

 cylinders of the pump, it is only neces- 

 sary to have sufficient head for the 

 water to flow to the pumps by gravity. 



These pumps are automatic in their 

 action. They have a float in the re-

SAVE THE MOST VALUABLE PART OF CONDENSATION-ITS HEAT. 



They automatically 

 return all the condensa- 

 tion from the steam lines 

 directly to the boiler at 

 almost evaporation 

 temperature — less coal 

 is required to convert it 

 into steam again — hence 

 a great saving is effected.
