Externally-fired cylindrical boilers of all kinds are also out of the running on account of the inevitable deposit of scale on the bottom of the boiler, just where it is exposed to the greatest heat. The points to be borne in mind in regard to effective combustion of fuel -- proper complishing this, follow in natural sequence. of Now, as to the best type of boiler for the economical production of steam. It may pretty well be taken for granted that all surviving well-known types of boilers are capable each in its own way, and for its own purpose, effective steam-raising if properly handled. Of these the principal in general use are the Lancashire or double-flued cylindrical boiler; the Cornish or single-flued boiler; the water-tube boiler, in various forms; the loco-type boiler, and the internally-fired, return-tube boiler.
