Abstract

Heating boiler, comprising an upper loading door and two lower ashtray and burner doors, characterized in that it comprises; - a plurality of closed tubular elements of oblong configuration attached by their larger sides and coupled together by respective upper and lower common collectors through which circulates the heating water that makes its entry through the lower manifold distributed in each element on both sides of the same ascending the sides and effecting their exit by the upper collector according to a symmetrical circulation, whose elements consist of a front element incorporating the access doors, at least one intermediate element adjacent to the front element provided with at least one upper intermediate section that hydraulically joins the sides for the circulation of water between them and that defines at least one step for the exit to the exterior of the preceding fumes of the combustión chamber, defined in the interior space of said elements, forcing the fumes to perform a longer travel a zig-zag and thereby get the maximum exchange thermal, and a subsequent element that closes later the combustión chamber through which the entry and exit of water is made, and the exit of the fumes to the outside whose elements in its lower sections define a facing entrants that constitute the fixed grills of the combustión chamber which are cooled by the heating water, an uncooled ashtray provided with the corresponding ash tray is provided below them; - upper load access doors and bottom of ashtray and burner incorporated in the front element that are heat insulated, whose front element incorporates at least one of both lower doors which have dimensions corresponding to the lower space of said front element so which individually close said space according to the type of combustión to be used while remaining the other door open, such being the arrangement that when the burner door closes said space is locked in the closed position and at the same time blocks the upper loading door preventing its opening ; - an oscillating grid between two main positions, an upper one that frontally closes the combustión chamber and a lower one folded in front of the ashtray; y - possibly a deflector screen in correspondence with the element of a single smoke passage; whose arrangement allows solid fuels to be used by arranging the closed ashtray door and the grate in the upper position, and liquid and gaseous fuels by opening, and where appropriate by arranging the burner door with the built-in burner closed and locked, in whose arrangement it blocks the door load preventing its opening, with the grid down in front of the ashtray placed the deflector screen, proceeding inversely if you want to use the other type of fuel.
