22-inch flue from the smaller boiler to the 

 36-inch flue? A. & H. W. 



The boiler to be installed is probably 

 rated at adjout 120 horse-power and it 

 should have a grate about five feet square 

 to afford the maximum of power. If 

 tested at eighty pounds, it should cer- 

 tainly be safe for thirty pounds. 



The stack described should be amply 

 large for the two boilers. The boiler at 

 present in use is about thirty horse-power. 

 If, as I understand your plan, the larger 

 boiler will be connected with th? 

 chimney by a 36-inch flue and the other 

 boiler will be connected by means of ;i 

 22-inch flue to the end of the large flue, 

 this should give good results. 



STEAM IN UNDERGROUND PIPE. 



I shall soon start a range of houses, 

 and can get my heat from the coal mine 

 at the price the coal would cost. The 

 local steam fitter says that it will not 

 pay me to do it, as there is something in 

 the soil that rusts the pipe out in a year 

 or two, even if it is run through a tile 

 and the tile is cemented. I should like to 

 know whether there is any way in which 

 the pipe can be packed to keep it from 

 rusting. The steam will have to travel 

 600 feet before entering the greenhouses. 

 At a pressure of sixty to 100 pounds, how 

 large should the pipe be to heat four 

 houses, 29x142 feet? The local man says 

 i^-inch will be large enough. About 400 

 feet from the greenhouse there is a fall 

 of about ten feet below the level of the 

 greenhouse, and in the other 200 feet 

 there is a rise of about four feet to the 

 bottom of the boiler. Would there be 

 any trouble in the heat circulating from 

 that dip in the pipe? Kindly give any 

 other information you can regarding 

 valves, traps, etc. E. 0. H. 



While one would have to be familiar 

 with the local conditions to give a definite 

 answer, it seems probable that with 



What W. J. Palmer & Sou, Lancaster and 

 Buffalo, New York, have to say of 



"DETROIT" AUTOMATIC RETURN 

 STEAM TRAPS 



"We have been using two of your 'Detroit' 

 Traps the past winter on a Gravity System 

 and find they keep -the pipe clear of conden- 

 sation, therefore maliin? the return do as 

 much as the flow. We are able to heat with 

 less number of pipe than formerly and keep 

 the houses far more even in temperature." 



"Detroit" Traps will do the same for you.

proper care a pipe can be carried under- 

 ground from the coal mine and at the 

 same time can be protected from any- 

 thing injurious in the soil water. 



In the first place, a drain tile should 



be placed a few inches below where the 

 pipe is to be. Then, after painting the 

 pipe with two heavy coats of asphalt, 

 cover it with asbestos packing. It will 

 not be advisable to use anything less
