. Perni di banco per ferrovie elettriche e due del tipo Nichols a moto alternativo verticale. In previsione della carenza di carbone, due delle caldaie sono state predisposte per la cottura del petrolio e sono state fornite le attrezzature complete del sistema Wallsend-Howden, con i serbatoi di stoccaggio necessari, i filtri e le pompe. Poiché la carenza di carbone e di olio, dovuta alle condizioni di guerra, è diventata più acuta, altre caldaie erano adattatedper la cottura del legno. La situazione attuale sarà sotto-rimasta dalla dichiarazione che durante una settimana recente la pianta ha consumato 72i tonnellate di carbone, 154 tonnellate di petrolio e 690 tonnellate di legno.

In anticipation of the shortage of coal two of the boilers were arranged for oil firing and a complete equip-ment of the Wallsend-Howden system was provided, with the necessary storage tanks, filters and pumps.As the shortage of both coal and oil, due to war con-ditions, became more acute, other boilers were adaptedfor wood firing. The present situation will be under-stood by the statement that during a recent week theplant consumed 72i tons of coal, 154 tons of oil and690 tons of wood. The calorific value of the wood isfrom a quarter to a third that of coal containing 15, 000B.t.u. per pound. Water is pumped from the River Lujan to a reser-voir, where it is treated with alumino-ferric to precipi-tate the sediment. Alternative Arrangement for Coal and AshesHandling x The storage and handling of coal is provided for bymeans of an elevated railway track running alongsidethe boiler house at firing floor level, a gantry running VTT7.

The coal can be lifted from the railway cars andfilled either direct into two 15-ton receiving hoppers, or into bottom-discharge wagons which can be hauledalong the elevated siding by a winch until they comeover the receiving hoppers. In the latter case the coalpasses through crushers to gravity bucket conveyorsby means of which it is elevated to a distributing con-veyor, which in turn discharges it into the coal bunkerslocated above and between the two rows of boilers.The coal bunkers are of 1000-tons capacity, and theyare built of mild steel plates lined with reinforced con-crete and with bottoms V-shaped in sections. The stock coal is lifted from the trucks and storedbelow and around the gantry in
