January, 1926 Pulverized Coal (Continued from Page 30) specially designed to compact the ma- terial as it approaches the discharge end of the pump, and this packing effect serves to prevent the return of compressed air through the worm to the hopper. As a result the pump may be operated with an open hopper as long as an adequate supply of material is received by the hopper, which makes it ideal for transporting the coal from the mill spout to the furnace bin in one operation. The whole system is enclosed, so that there is no opportunity for dusting between the time the coal enters the mill and the time when it is delivered into the bin at the furnace. The system is also used to take pulverized coal from a storage bin and distribute it to such points as re- quired. A complete electrical signal- ing system is used to indicate to the operator when the bin to which he is pumping has been filled, and to permit him to operate diverting valves to change the flow to other bins which are in need of coal. The operation is usually made automatic, in order to avoid any chance of overflow. This system of conveying has been used to elevate pulverized coal over a hundred feet, and to convey it dis- tances of over a mile, the line pres- sure and the power required, which is comparatively low, depending upon elevation and distance. But little compressed air is required, and hence no cyclone is needed at the point of discharge from the pump line. The material as discharged is completely fluid, and levels off perfectly in the bin, retaining this condition for some time. In addition to the advantages of The president of the Fleet corpor- ation has announced the consumma- tion of the following sales of ton- nage: HEGIRA, ocean cargo vessel, 11,600 deadweight tons, 7800 gross tons, for $250,000, to the Hegira Steamship Co., Tacoma, Wash. The Hegira Steamship Co. is a subsidiary of the Weyerhaeuser Timber Co. LAKE CHELAN, lake type cargo, 2942 dead- weight tons, 2010 gross tons, for $33,000 to the Consolidated Navigation Co., Baltimore, LAKE HELEN, lake type cargo, 2989 dead- weight tons, 1998 gross tons, for $28,000 to the Consolidated Navigation Co., Baltimore, Md. Coquina, lake type cargo, 3180 deadweight tons, 2140 gross tons. CorsIcANA, lake type cargo, 3303 dead- weight tons, 2146 gross tons. The two foregoing ships were sold for $25,vuvuv each, cash consideration and contracts Recent Sales ot Ships MAKINE REVIEW dustlessness, simplicity, and adaptibili- ty, the first cost of this system is low and likewise the charges for labor and repairs, and the repairs are easily and expeditiously made. The cost of preparation of pulver- ized fuel may be divided into five main items: power, labor, repairs, fuel for drying, and interest and de- preciation. Of these, drier fuel might logically be eliminated, inasmuch as its effect is largely returned in increased heating effect of the coal burned un- der the boilers. Approximately 1 per cent of the total fuel is required for drying, and when waste or steam is available the item disappears. The remaining items decrease as the ca- pacity of the plant increases, and it is this fact which accounts for the commanding position now assumed by pulverized coal in the field of large power plants. Costs Not Excessive No set figures can be given for the ratio between these items, as they will vary irregularly with locality and with size of plant, but a maximum of 20 kilowatt-hours per net ton bituminous coal may be stipulated, covering the entire process from crusher to fur- nace, and the charges for power, labor and repairs may be taken roughly as in the ratio 5:3:2. These three items in a plant having a capacity of 400 tons per day, assuming power avail- able at 1 cent per kilowatt-hour and labor at 50 cents per hour, would amount to 18 cents, 10 cents, and 8 cents, respectively, or a total of 36 cents per ton without financial charges. The actual preparation costs in any particular instance may be readily determined, and a large amount of published data give complete costs under operating conditions. to perform specified alterations or betterments, Pillsbury & Curtis, San Francisco.
