ECONOMICAL USE OF FUEL IN CREAMERIES. 



13 



to design a boiler setting that will meet exactly the requirements 

 of a given set of conditions. With the type of setting shown in 

 figure 5 and dimensions in Table 2, however, it is believed that 

 satisfactory results will be obtained when using an average grade of 

 soft coal. The dimensions of the distance, between grates and 

 boiler are to be considered as only approximate minimum limita- 

 tions. If the height of the. boiler room will permit, this dimension 

 should be at least the diameter of the boiler, but in most milk plants 

 and creameries to build the boiler-room ceiling higher would neces- 

 sitate an increased expense in the construction; hence to a certain 

 extent the height given is a compromise between the cost of building 

 and the better combustion of fuel.
