Some have advocated, as the most economical method,burning the refuse at the temperature required to render all fumesharmless, as the wear and tear on the furnace is then very smalland the cost of repairs a minimum. Until the past two or three first attempts were made in the ordinary types of Lancashireand Cornish boilers; that the results were satisfactory the follow-ing test, made at Salford Sewage Works, will show: Boiler—Lancashire, 28 ft. long, 7 ft. diameter, 2 ft. 9-in. used—Unscreened refuse. Duration of test—14 hours 10min.:. J CONTAINING HOPPER D FIG. 2—PLAN OF GRATE WITH BOILER SETTINGS years practically all the furnaces erected in England have beenconstructed on this principle. They have in all cases had a highchimney to carry away any fumes that escaped cremation, but sonumerous were the complaints made by those living in proximityto the works that it was found necessary to furnish some meansto abolish this nuisance. To meet this difficulty, the fume cre-mator was invented. This consists of a reverberatory arch withbaffle brick ribs projecting from it, serving to deflect the gaseson to the top of a red-hot coke or coke breeze fire. This adds tothe cost of destruction about 6l/2 cents per ton of refuse. Weight of unscreened refuse burned, lbs 18,704 Average steam pressure, lbs Temperature of feed water, degs. F Water evaporated during test, lbs 36,000 Refuse burnt per hour, lbs 1,320 Water evaporated per hour, lbs 2,540 Water evaporated in lbs. per lb. of refuse from feed Water evaporate
