Abstract (en)
[origin: EP0193234A2] The boiler is constituted by a combustion chamber (20;120) with oblique side walls (2, 4; 102, 104) adapted to cause the solid fuel to descend automatically by gravity towards a lower grid (5, 105) where combustion takes place. The fuel is introduced through two capacious upper apertures (7, 8; 107, 108) provided with smokeproof covers. The fluid to be fed to the heating bodies is heated in a central cylindrical body (14, 114) with flue pipes. The central cylindrical body (14; 114) can be made either in a version for feeding with solid fuel only or in a version for mixed feeding, in which case the boiler is provided with appropriate supports for a conventional burner (17). The main advantage of the boiler is its great autonomy of feeding with solid fuel which is introduced thereinto in considerable amounts - if desired, in the form of large economical pieces of wood logs - which, however, are burned gradually in time.
