The forms in which steam generators are built are numerous,but may be divided into three classes, viz : stationaiy, loco-motive and marine boilers, which terms designate the uses forwhich they are intended ; in this work we have to deal mainlywith the first-named, although a description with illustrationis given of each type or form. 50 Maxims and Instructions, . AN UPRIGHT STEAM BOILER. To illustrate the operations of a steam generator, we give tliedetails of an appliance, whicli may be compared to the letter Aof the alphabet, or the figure 1 of the numerals, so simpleis it. Fig. 11, is an elevation of boiler, fig. 13 a vertical sectionthrough its axis, and fig. 13 a horizontal section through thefurnace Fig. 11. Fig. 12. The type of steam generator here exhibited is what is knownas a vertical tubular boiler. The outside casing or shell iscylindrical in shape, and is composed of iron or steel platesriveted together. The top, which is likewise composed of thesame plates is slightly dome-shaped, except at the center, whichis away in order to receive the chimney a, which is round inshape and formed of thin wrought iron plates. The interioris shown in vertical section in fig. VI. It consists of a furnacechamber, h, which contains the fire. The furnace is formedlike the shell of the boilor of wrought iron or steel plates byflanaing and rivetinsr. The bottom is occupie(i by the grating,on which, rests the incandescent fuel.
