The present invention relates to room-heating devices of the live-combustion type comprising a hearth open to the atmosphere in which the combustion is effected, and working on a closed circuit without any evacuation chimney, said device comprising in combination: suction means for creating an upward flow of the gaseous mixture formed by the primary air necessary for the combustion and the gases generated by said combustion, and solid particles or smoke also generated by said combustion and conveyed by said gaseous mixture; said gaseous mixture and said solid particles being passed through purifying means comprising devices for separating said combustion gases from said solid particles and for holding back said particles so as to deliver a purified gaseous fluid, a re-cycling circuit being coupled to the outlet of said purifying means for re-cycling the purified fluid to the hearth of said device. |
