Abstract: Burning stove (1) combined with a Stirling engine (2) for producing electricity or to be coupled to a heat pump where the heater of said Stirling engine (3) is placed inside the stove (1), that comprises t o or more burners (4) arranged on the same plan and that the axis of the heater (3) of the Stirling engine (2) passes through the barycenter of said t O or more burners (4). The stove can be advantageously a pellet stove with one or more heat exchangers (8).

Abstract: Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating comprising a hearth fuelled by pellets or biomass grains, at least one plate to cook food and two heat exchangers to heat water for domestic heating wherein the cooking plate is located above the hearth fuelled by pellets or biomass grains, said two heat exchangers are positioned at the sides of the cooking plate, that on one side of said heat exchangers two inclined deflection plate are mounted that forces the combustion fumes to go up to touch the cooking plate and then to flow on the heat exchangers, the heat exchangers are two bundles with parallel pipes, on said pipes of said bundle heat exchangers at least one fixed deflection plate is located, said fixed deflection plates are perpendicular to said pipes of said bundle heat exchangers, each fixed deflection plate has a unique gateway that is positioned above or below each pipe bundle.

Abstract: Double fuel burning stove formed by an external casing, characterised by the fact that said stove is composed of two hearths, a first hearth (4) for one fuel and a second hearth (5) for a second fuel, the second hearth (5) being placed above the first hearth (4) and the second hearth (5) is completely separated from the first hearth (4).
