An Elementary Treatise On Steam And The Steam Engine Stationary And Portable Being An Extension Of The Elementary Treatise On Steam Of Mr John Sewell

Excerpt from An Elementary Treatise on Steam and the Steam-Engine: Stationary and Portable, (Being an Extension of the Elementary Treatise on Steam of Mr. John Sewell) In issuing this volume, it is necessary to state that Mr. Sewell's work has been entirely re-cast, and, to a considerable extent, re-written. Much of what was, in the original book, of but general interest, or had become obsolete in consequence of the advances of scientific investigation and of experience, has been replaced by matter more directly interesting to the steam-engineer. The mechanical theory of heat is explained and exemplified, and the heat of combustion is given for various combustibles. An extended notice of peat as a fuel has been supplied; and new chapters on steam, steam-boilers, and stationary and portable steam-engines are added. The action of, steam in the cylinders of steam-engines, and the conditions required for economically working steam by expansion, as originally investigated by the Editor, are treated in considerable detail. The compound engine is also discussed, in addition to the various classes of single-cylinder engines; and the most recent recorded performances of portable engines are presented to the reader, together with a summary account of that nearly forgotten class of labouring machines - the traction-engine.
