Abstract

16,613. Tornack, M. Sept. 21, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Heating water.-A sectional boiler consists of a number of rows of sections g, which are so formed and arranged that each two adjacent rows enclose a combustion chamber f, and rows of sections and furnace spaces succeed one another alternatively along the length of the boiler. Each section g is provided with ribs which, when the sections are assembled in the usual way, form the sides of the flue passages u between the water spaces in the sections. The combustion products may enter the flues u from both sides of the combustion chamber or, as shown in the middle sections of the boiler, Fig. 2, they may enter the flues from one side only of the combustion chamber. The products pass downwards through the flues u and enter large exhaust flues o, which open into a common uptake. Apertures which are closed by covers p are provided at the top of the boiler to afford access to the flues. In a modification, the ash chambers a are arranged in the flues o instead of being placed above them, as shown.
