Therefore in preparing peat 10c it is being pumped additional amount of water and hydrocarbon liquid through a'suitable mill, wherein onits passage through the same the peat willlbe ground with the other ingredients into a suitable emulsion.

Water to the extent of eighty per cent. of the compound can be utilized in making an emulsion for ordinary work, such as gasifying to burn in boiler-'furnacesto generates team, while in some classes offwork where the heat is cumulative upward of ninety per cent. of

water can be used, whichconstitutes avery important discovery when. practically ap plied to furnaces in which refractory ores and other analogous substances are treated.

The proportions of the different ingredients are varied to make different qualities of gas or to produce a flame suited to different kinds of work. The petroleum may be varied from five parts to twenty or more parts, and the parts s ondingl y varied. The peat may be ground alone and then mixed with water-and the oil in suitable proportions, and the mixture may be agitated for maintaining uniformity while into gas-generating coils or conduits.

One of the formulas used in practice and which givessatisfactory-results 1s as follows: hydrocarbon oil, twenty-five percent. peatpaste, thirty per" per cent.

By grinding the peat to a fine paste the cellular structure thereof is broken, thereby libcrating a viscid liquid composed of hydrocarbon oil and water which is in the condition If oil and water are at the viscid liquid combines with the oil and water form of an emulsion.

In Letters PatentNo. 728,854, granted to William F. Browne- May.26, 1903, an emulsion-fuel compound composed of water is fully described and claime What is herein claimed is- 1.

The herein-described method of preparing an emulsion-fuel compound which consists in reducing peat to a state of molecular division and grinding .it with hydrocarbon liquidiand water, in suitable roportions, till the ingredients are emulsified and the heavier matter caused to remain in suspension 'ethroughout the mass in the condition of an emulsion, adapted to be forced into heated conduits for generating combustible gas.
