In fig. 116 is shown a form of cylindrical boiler, patented by Messrs. Biddell and Balk, and manufactured by Messrs. Ransomes, which enables the firebox and tubes to be withdrawn from the shell or barrel, so as to give facility for removing and cleaning out the incrustation and dirt, which is so injurious in some cases, and which cannot easily be removed from boilers of the usual form. In this patent boiler the back tube plate, as well as the front outside plates, are bolted to flanges riveted to the shell of the boiler. These flanges being truly placed, the steam-tight joints are made with as great a facility as the cylinder-cover joint of a large steam engine. Where the water is very dirty and leaves much deposit, this boiler is strongly recommended.
These boilers, as well as the ordinarily formed boilers, are constructed with especial reference to durability and strength. The bulk of the plates are of best Yorkshire quality, the remaining plates being Staffordshire. Ample water space is given round the fire-box and between the tubes, so as to ensure free circulation of the water. Each boiler is tested to double its working maximum pressure.
The boilers are mounted upon iron or wooden wheels, according to the wish of the purchaser, but iron ones are recommended as generally more durable and better adapted for change of climate. |
