THE SMOKE PROBLEW. 



Chimneys will still be needed when the 

 so-called smoke problem is solved. The 

 popular solution consists in changing the 

 color of the gases flowing from the chim- 

 ney from black to a light gray. At least, 

 this is all that the public and the smoke 

 inspector will demand. But even when 

 this problem is well solved, our chimneys 

 must continue to discharge immense vol- 

 umes of heated gases, and these gases will 

 often carry with them fine particles of 

 ash which cannot be burned; all of which 

 may produce something of that disagree- 

 able haze which floats over manufacturing 

 cities. The dense black smoke from chim- 

 neys is certainly a nuisance. It can be 

 stopped for about ninety per cent of the 

 time, and if this is accomplished a most 

 wonderful improvement will be observed 

 in the atmosphere. 



It often has been stated what relation 

 should exist between the weight of coal 

 burned in a grate and the weight and 

 volume of air required for perfect com- 

 bustion. It is sometimes more striking, 

 however, to bring out this point by using 

 a larger unit than the single pound. Take, 

 for instance, a 100 horse-power boiler 

 plant. Many such plants would burn 500 

 pounds of coal an hour; the air supplied 

 would weigh 10,000 pounds and the vol- 

 ume of this air at a chimney temperature 

 of 500 degrees would be about 240,000 

 cubic feet. The chimney for this plant 

 must therefore discharge nearly 10,500 

 pounds (5.22 tons) of gases into the at- 

 mosphere each hour ; that is, for each ton 

 of coal burned the chimney will discharge 

 from eighteen to twenty-two tons of gases. 

 To keep these gases of the right color and 

 composition for ninety per cent of the 

 time is the problem to be solved, not only 

 by florists in residence districts, but by 

 those who Avant to keep their glass clean. 



TWO SMALL HOUSES. 



We are building two connected green- 

 houses, each 19x35, ten feet six inches to 

 the ridge and five feet six inches to the 

 eaves. The south gables will be of glass 

 to within three feet of the ground. The 

 sides will have eighteen inches of glass. 

 The north gables will be protected by a I 

 boiler-shed. The sides, and the south '

DETROIT" Return Trap 



AND YOU BUY A GUARANTEE 



It takes 90 to 120 lbs. of steam per horse power to operate 

 an ordinary boiler feed pump. "Detroit" Return Traps 

 require only about one-tenth that amount. Why not save 

 the nine-tenths ? 



Write us size of boiler and number of square feet of glass 

 in your greenhouses, for our pioposition.

gables up to the glass, will be double 

 boarded, with paper between. The houses 

 will have two side benches, raised, under 

 which we would like to run the heating 

 pipes. The center bed will be on the 

 ground. We expect to grow asparagus in 

 the center. 



Will a two horsepower tubular boiler 

 give sufficient heat with hot water for a 

 climate where the temperature rarely 

 goes below zero? How shall we pipe these 

 houses? Please give size and number of 

 pipes. C. & R. 



The two houses, each 19x35, will re- 

 quire at least ten 2-inch pipes in each 

 house, with hot water, to carry a tem- 

 perature of 50 degrees during your cold- 

 est weather. A flow with four returns 

 under each side bench probably will prove 

 as satisfactory an arrangement as you 

 can make. The boiler in question will 

 carry the houses in mild weather, but is 

 too small for best results during cold 

 weather. You should have a boiler rated 

 to carry about 750 square feet of heating 

 surface for best results. Your boiler will 

 carry about 350 square feet. F. R.
