Abstract
A REPORT issued by the Department of Scientific and Industrial Research (H.M. Stationery Office, 9rf. net) records a test by the Director of Fuel Research on a plant erected by the British Coal Distillation Co., Ltd., at Newbold, Leics., and designed to prepare a smokeless fuel from an entirely non-coking coal, high in ash. The unwashed coal is first dried and passed through a revolving inclined retort, where it is carbonised at 600° C. by hot products of combustion of producer gas. The residue from the retort is discharged into a trough of water, and the ‘clean’ coke, which floats, is skimmed off the surface, while the dirt sinks and after removal is used for fuel on the plant. The resultant ‘clean’ coke is made with pitch into briquettes, which are stored to give a domestic fuel. The throughput of the plant as claimedâ 100 tons per dayâ was substantially confirmed, giving a fuel which was considered satisfactory for the open grate, a notable achievement for such a raw material. This is a technical test made in accordance with the normal practice of the Department, and does not purport to give an opinion about the commercial success of the process.
