The Iron and steel magazine . the re-quired volume or the stove-heating surface in hope of better result,a practice which has been carried out for years in most workswithout resultant improvements. The rule for finding the work-ing capacity of a furnace when the sizes are given is as follows: vSquare the diameter of the bosh in feet, multiply by thetotal height of the furnace in feet and divide by one will give the nominal make per 24 hours for that size offurnace, provided the furnace equipments are in accordance withthe other rules given; so that the formula for a properly pro-portioned and equipped furnace will be as follows: B2 x H 100 Where make in tons per day. B = bosh diameter. H = total height of furnace. Blast Furnai e ( ah illations Therefore, the 260-ton furnace which we arc now working outwill give: 1 8s X So = 2 s<;.20 tuns per (lav ?—say. 260 tuns. 100 This shows that 80 feet is the proper height of the furnace andthat 18 feet is the right diameter of the bosh for that make, 1 00. Section of 18-foot X 80-foot FurnaceIThis furnace section is to illustrate contents calculations.] IO The Iron and Steel Magazine according to the method of calculating the output capacity,which has always proved correct. As an example, we will takea smaller furnace of 93 tons output per day of 24 hours. Thissmall furnace has a total height of 55 feet, a bosh of 13 feetdiameter and will work out as under: i32X55 JOO = tons per day — say, tons. Let us now take as a further illustration a larger furnace,having a bosh of 22 feet diameter and a total height of 100 dimensions will work out as follows: 222 X TOOIOO = 484 tons per day.
