A boiler provided with a burner chamber for a burner firing system and a combustion chamber for a solid fuel firing system, both chambers being arranged horizontally side by side in a common boiler water space enclosed by a horizontal outer boiler body. The combustion chamber has an approximately elliptical cross-section with vertical major diameter and the burner chamber has a round cross-section, the longitudinal center lines of both chambers being substantially at the same level. Both chambers are connected at their front ends with two separate horizontal ancillary heating passages extending axially parallel above the chambers within the boiler water space and having rectangular cross-sections with horizontal major cross-sectional dimensions and with internal comb-like ribbings. The outer boiler body is made of a metal sheet shaped in one piece by rolling into a hollow body of non-circular roundish cross-section. |
