UTILIZATION OF WASTE HEAT FROMBLACKSMITH FURNACES No one who has Ijeen around blacksmith shops can havefailed to notice the flames from the furnaces rising out ofthe stacks. This is such a familiar sight that it is taken asa matter of course: but on second thought it is quite evidentthat the flames must carrj- away a great deal of heat that hasnever been utilized. At the same time that this heat is goingto waste, fuel is being burned in some adjacent power plantto furnish steam for hammers, shears and blowers in the. Locomotive Boiler Set Over Furnace to Supply Steam to Hammers blacksmith shop. When there is such urgent need for fueleconomy, why would it not be well to utilize the heat of thefurnaces to generate steam for the smith shops? This is by no means a new idea. Boilers mounted overfurnaces are to be found in shops built many years ago. Topeka, Kan. In these shops the heat from the furnaces isused to generate steam in locomotive boilers which supplythe steam hammers and also a few steam-driven tools. Inthe interest of fuel economy in railroad shops, a descriptionof the plant may not be out of place. The furnaces over which the boilers are placed bum fueloil. They are equipped with combustion chambers and thefurnace proper varies from 8 ft. to 12 ft. in length. A viewof the cross-section of the furnace is shown in theillustration. The oil is sent in through two burners in theend under a pressure of about 12 oz. from a fan blast. Anauxilian* air supply enters
