The Economy of Burning Small Coal.

It is a common delusion that a small fuel must necessarily be of low calorific value, and accordingly of doubtful economic value even if it can be burned. As a matter of fact, many small fuels are of excellent calorific value, and when burned with suitable will show a phenomenal saving. Again and again have I seen an evaporation of ten pounds of watar per pound of fuel obtained wltj»_ slack from Welsh steam coal 'weting from 5 to 6 shillings per too stss than the large coal. Slack tr» & a good Welsh steam coal Is really remarkable value for money as compared with the large coal from which It Is separated. Generally speaking, twenty tous of such slack will evaporate fully as much water as nineteen tons of the large coal, and assuming their respective costs per ton to be 15 shillings and 20 shillings the saving to the steam user will be the difference in cost between twenty tons at„ 15 shillings per ton and nineteen tons at 20 shillings per ton, say £4.—W.
