Stokgng. T - E - In crde1 'to illustrate the personal element iirtrcduced in good and bad stoking, we may quote the competition which was carried out at Messrs. Davey Brothers', of Sheffield. Five stokers were made to fire. The same boiler with, the same coal and with the steam pressure about the same. The best stoker was able to obtain an evaporation of 91b. Of water per pound of coal, the worst evaporation being lb. Per pound of coal. The difference is here 22 per cent. The opportunities afforded for in creasing the efficiency of the: boilers. Were, in this. Instance limited. A well-laid fire, which by constant attention is prevented from. Burning into holes, is one of the chief items in securing a high. Evaporation. Keeping the fire bars clean, and regulating the dampers for a maximum quantity of air just after firing contributes greatly to high efficiency. Beyond these points. There is little opportunity for exercising skill in stoking, and yet these tests show clearly how very important the simple operations involved in firing a boiler become. The very simplicity is one cause for neglect.
