From the sketch it is seen that the 

 boiler house is in the middle of the 

 north side of the range and the range 

 has a cross aisle at that point for the 

 main feed line. From the size of the 



Jdpe, it might be inferred that hot water

 be returned to the boiler, it is evident 

 that steam is to be used as the heating 

 medium. 



For low-pressure steam, a 5-inch steam 

 main should be used until the supplj 

 ph>e8 to the first house have been taken

Help Save the "White 

 Coal of Industry" 



The boiling hot water resulting from condensation in 

 your steam lines is worth money. You have paid for 

 it in terms of coal. It contains valuable heat units. 

 It is the "White Coal of Industry"— it should not 

 be wasted. 



And it need not be wasted. The Morehead Back- to- 

 Boiler System will save it for you by returning it to 

 the boiler at temperatures as high as 400 degrees 

 Fahrenheit. It reduces coal consumption an average 

 of 20%. At the same time your steam will be 

 "drier" and more efficient; your production speeded 

 up and profits increased.

 head System will do in your plant.
