A Manual of the Steam Engine #265598

In the sixth and seventh chapters, the various parts of the modern steam engine are considered separately, preparatory to the consideration of them in their com bined condition, and in their relations to each other, in subsequent chapters. Some preliminary remarks are made on the laws of combustion, on the effect of fuel in producing steam, and on the modes of measuring the pressure, or tension, of steam. These chapters are then devoted to the consideration of the construction and pro portion of the several parts of the steam engine, as of the safety apparatus; of the boilers, with the precautions necessary for their safety and effect; of self-regulating furnaces; of cylinders and pistons; of valves, with refer ence to their form and mode of action; of the mechanism by which the valves are worked; and of the apparatus for indicating the pressure of the steam in the boiler.
