CAPAQTY OF BOILER. 



I have traded for a fire-box boiler, 

 twelve feet long and forty-two inches 

 in diameter. It has forty 3-inch flues, 

 nine feet long, and a steam drum two 

 feet high. The grate is 42x48 inches. 

 Please tell me how many feet of glass 

 this boiler will heat economically, with 

 low pressure steam, here in northern 

 Kentucky. Is a check valve necessary 

 for low pressure steam? G. O. K. 



Such a boiler should be able to handle 

 about 18,000 square feet of expansion 

 on a 50-degree basis. The boiler has 

 surface enough to provide steam for 

 about 2,500 square feet of radiation, 

 and this should maintain a temperature 

 of 50 degrees in your climate in about 

 18,000 square feet of exposure, figuring 

 roof, ends and sides exposed. If the 

 water line of the boiler is four feet 

 or more below the radiating pipes in the 

 greenhouses, check valves will not be 

 necessary. I prefer to install them, how- 

 ever, in most plants, unless a water leg 

 is used to seal the boiler. L. C. C. 



WRONG LOCATION OF FLOW. 



As we are having some diflSculty with 

 our heating plant, I beg to ask you for 

 information as to what you think is 

 wrong with it. Our greenhouses are 

 built on a slope and we have one house 

 running north and south, which is 125 

 feet long. Our boiler is situated in the 

 south end, which is five feet lower than 

 the north end of the greenhouse. The 

 steam is carried to the top end through 

 a 3^-inch pipe, which supplies the re- 

 turn pipes from the north end of the 

 greenhouses. There are sixteen 1%-inch 

 heating pipes in this house, 25x125 feet. 

 The steam which condenses in this main

pipe, which is 125 feet long, has to run 

 back to the boiler through the main. 

 Now, where our trouble lies is this: 

 When we carry four or five pounds of 

 steam, water seems to disappear from the 

 boiler and it seems to force up in the 

 pipes at the highest point in the green- 

 houses. 



Do you think this 3% -inch main is 

 large enough to feed sixteen 114-inch 

 returns, and do you think that, with the 

 high pressure of steam — that is to say, 

 five or six pounds — the water will run 

 back through the main against the steam? 

 I am located in Alberta, Canada.
