TO BURN UP SMOKE.

Slaipto Mean* of Proem-tag 1“ Almost Complete Coneamptlon. The St Louis Post-Dispatch has interested itself in smoke consumers, and as a result makes public a device which can be applied without trouble to any furnace. It is not patented. This is how it is made: Bore four one-inch boles through the furnace front, just above the fire doors, as shown in cut. Run a three-quarter inch steam-supply pipe across the

front, with one-half inch T’s opposite each hole. To each “T” connect a S»iece of half-inch pipe of sufficient ength to reach through, forming the jets. Place a valve in the supply pipe, in front of the boiler, handy for firemen to regulate. A good way to make the jet is to forge a plug in the end of the pipe, in the end of which bore a one-eighth-inch hole.in-, cline the Jets at an angle on a line with the center cross line of bridge wall, clearing the fire. The opening of the fire-door must, be governed according to the draught. When putting in a fresh fire open the supply valve one or two turns, and in place of shutting the doors leave, them open about one inch, and if the; smoke does not disappear open themi a half-inch further. When the smoke has entirely disappeared the proper amount of air to complete the com-; bustion is being admitted. The open-' ing of the doors is very necessary.i The large area around them admits

of an even distribution of air obtained in no better way. The in-, creased combustion equalizes the. small amount of steam used. This device is not injurious to the boiler in any way, and is recommended by the St. Louis boiler inspectors.
