Side Flues 



At the end of each of the spaces or cross Are 

 ch»nnel8, between each section. Is an opening 

 or flue, that leads from this lower story, or com- 

 bustion chamber. Into the upper story where the 

 real flie travel begins. 



You can easily see that If the opening for the 

 hot gases and smoke learling Into the upper 

 story, were all at the back of the boiler, the hot 

 gases and smoke would rush to those back sec- 

 UoDs and draw a large amount of heat away 

 from the front ones. This Is bad because only 

 the back sections are fully efficient. The side flue 

 openings In the Burnham draw an equal amount 

 np each side flue opening between' each section 

 and make each section •qnally efficient. 



Cross Channels 



The cut at the left shows you that tb'e shape 

 of each water filled part of eai'h section directly 

 over the fire. Is like a blunt ended wedge. This 

 gives a deep space bttween each of the sec- 

 tions Into which the hottest part of the flru is 

 pockett-d, and a large proportion of the heat 

 directly ab8ort>ed from It by the water. It's 

 the dlrectest kind of direct surface that can't 

 be beaten for economy. 



Fire Travel 



Once np In the second story, the hot gases and 

 smoke start on their long Journey back and forth 

 three times on each side of the boiler. This 

 traveling ts done between water lined walls that 

 hungrily grab what heat Is left, leaving only 

 enough to form the necessaiy draft in the 

 chimney. It comes pretty close to squeezing 

 the last drop of heat out of every pound of ccal. 

 It comes go near It In fact, that no other boiler 

 can come as near it, and be a fact. 



How al>out it- do you want to save money on 

 your boiler when you buy it; or save money on 

 your coal every year after the boiler is bought? 

 The Burnham will do that last thing for you. 



We can ship at once.

The flows may be on the plates and 

 the returns on the walls in the house 

 with the beds, but in the other house 

 it would be fully as well to have the 

 returns under the benches and the flows 

 just below the purlins. 



While it would be preferable not to 



use the 1-inch pipe for the returns, it 

 would give fairly good results if a 

 generator is attached to the system. 

 Thirteen or fourteen 1-inch returns 

 will be required in each house for a 

 temperature of 50 to 55 degrees. In 

 case roses or other plants, needing 60
