in the boiler which prevents the water 

 from coils 2 and 3 from entering the 

 circulation. 



If it is not possible to locate the trou- 

 ble outside of the boiler and if the ob- 

 struction cannot be removed through 

 the return port, I would suggest joining 

 the returns from the three coils to a 

 3-inch main return and connecting this 

 with the boiler at the point where coil 1 

 is now connected. It would be prefer- 

 able to run the flow pipes downhill, plac- 

 ing them on the plates, though such a 

 change would not materially affect the 

 return of the water. The fall of flow 

 and return pipes need not be more than 

 one inch in fifteen feet and the returns 

 should be run as high as possible. 



WATER-MINED NUT COAL. 



Will you please tell me the value of 

 water-mined nut coal as compared with 

 the ordinary anthracite? Can the water- 

 mined nut coal be used successfully in a 

 Lord & Burnham boiler! 



A. H.— Conn. 



No definite figures are at hand regard- 

 ing the two classes of coal mentioned, 

 but in a general way it might be said 

 that, as compared with the ordinary egg 

 and furnace sizes of anthracite, the 

 water-mined nut coal would be worth 

 from twenty-five to forty per cent less. 



Whether the water-mined nut coal can 

 be used economically will depend upon 

 its relative cost. Ordinarily, while it 

 might be found desirable for use in the 

 smaller sizes of hot- water heaters, it 

 should not be recommended for large 

 ones, if the cost per ton is more than 

 sixty per cent of the cost of a good 

 grade of furnace-size anthracite.
