AN UNDERGROUND STEAM PIPE. 



We ran a li/^-inch steam pipe under- 

 ground from the greenhouse to the resi- 

 dence, a distance of two rods. We laid 

 the pipe in a bed of cement and sand, 

 four inches in thickness around the pipe, 

 but a lot of heat escapes through the 

 cement and ground. What would have 

 been the best way to do the job, so as 

 to confine all the heat in the pipe? 



V. W. G. 



You really did one of the worst things 

 you could have done. A much better 

 plan would be to coat the pipe with as- 

 phaltum varnish, then wrap it in asbestos 

 paper and pack it in a box filled with 

 dry ashes ; or, better still, to string 8-inch 

 sewer pipe on the pipe and pack the 

 sewer pipe full "of mineral wool, having 

 the heating pipe in the middle of the 

 sewer pipe. L. C. C. 



DIAMETER OF SMOKESTACK. 



We have a tubular, return boiler, four- 

 teen feet long, with twenty-five 4-inch, 

 tubes, fourteen feet long. Our grate is 

 four feet wide and five feet long. The 

 dust chamber at the back is four feet 

 wide, three feet six inches high and two 

 feet deep. We burn a good quality of 

 West Virginia soft coal, but fail to 

 make the steam we require for a good 

 circulation. Our brick stack is nineteen 

 inches square, inside, and is twenty feet 

 high from the top of the boiler. It is 

 but ten feet high above the roof of the 

 boiler-shed. Before building it higher, 

 we should like to know if nineteen 

 inches square is large enough to give us 

 proper draft. We have four houses 

 20x100, one 15x100 and a shed 12x70. 

 We have a high pressure steam gauge, 

 and when the main valve is open we can- 

 not make steam enough to register. 

 There are no buildings or trees near to 

 mar the draft. Please give us the proper 

 dimensions of stack for the boiler we 

 have. R. S. 



The area of the chimney is almost ex- 

 actly right for the grate area. If the 

 height of the chimney can be increased 

 without decreasing its internal diameter, 

 the draft will probably be greatly bene- 

 fited. Sometimes a metal extension of 

 fifteen or twenty feet can be used at 

 small cost and to good advantage when 

 the chimney itself would not permit the 

 extension to this height if brick were 

 used. L. C. C.

ONE ADDITIONAL HOUSE. 



I have a new house, 28x101, which I 

 wish to heat with steam. Please state 

 the best method of piping it. The east 

 wall of the house joins an old house, 

 four feet to the gutter. The west wall 

 is six feet to the gutter, with three feet 



of glass and three feet of boarding. The 

 house runs north and south, and is eleven 

 feet to the ridge. It is slightly sheltered 

 on the north and west by a dwelling and 

 trees. It will contain five 4- foot benches. 

 We wish to use l^-inch pipe. The boiler 

 pit is eight feet below the level of the
