Excerpt from Notes on Boiler Testing

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.

Excerpt from Notes on Boiler Testing

The following notes on the testing of steam boilers are intended to refer only to such tests as are necessary to examine the economic performances of the boiler, and not to the testing which must be done to ascertain its structural defects. Such tests are no doubt of equal importance as affecting the safety of the community at large, and are generally dealt with by the boiler insurance companies. As far as the purchaser of a boiler is concerned, the question of paramount importance is that it shall raise steam economically. He may be assured by the insurance company that his boiler is safe. Here, however, the responsibility of the company will cease, unless private arrangements are made at additional cost for systematic tests of the boiler under steam with a view to ascertaining its steam-raising qualities. It is to this equally important side of the question that the author desires to draw the attention of large steam users, feeling, as he does, that the subject is not recognised by them as deeply affecting the profits of their industrial concerns. One has only to seek information amongst those who have set themselves to reduce their expenditure in fuel, to learn how much may be done in this direction. Sometimes improvements may be carried out at very small cost. In some instances the writer has been able to effect an economy of 10 per cent of the heat by the mere regulation of the air passing through the flues. Such a process is not costly. To leave the state of the fires to the care of the fireman is likely to lead to serious losses, his only object being to maintain a constant steam pressure and water level.
