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 eflficient; your production speeded 

 up and profits increased. 



Write today for facts and figures on what the More- 

 head System will do in your plant.
