mometer will register the minimum out- 

 door temperature for which the system 

 is planned. Thus, in the present in- 

 stance, it might be feasible to use a 

 somewhat smaller boiler if a tempera- 

 ture of 15 degrees below zero may be 

 expected only five or six nights during 

 the winter, with zero as a minimum on 

 other nights, than when we may expect 

 15 degrees bolow zero on a dozen or 

 fifteen nights, with 5 to 10 degrees be- 

 low zero on as many more. 



In a well glazed house, fairly well pro- 

 tected from the prevailing cold winds, 

 we would expect to maintain a tempera- 

 ture of 60 degrees in 20,000 square feet 

 of glass, or 50 degrees in 25,000 square 

 feet of glass, with the boiler described, 

 provided the outdoor temperature does 

 not reach 15 degrees below zero more 

 than three or four times during the win- 

 ter. This would require a good grade 

 of coal and careful firing, and even then 

 it would not be so economical of fuel 

 on extremely cold nights as it would 

 be if the amount to be heated were 

 5,000 square feet less, and this we would 

 consider the maximum amount to be 

 carried by the boiler described where 

 15 degrees below zero is the rule rather 

 than the exception.

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 S3 stem 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.
