Study of clean combustion of wood in a stove-fireplace with accumulation

The paper presents the results of works aimed at the reduction of carbon monoxide (CO) emissions to the atmosphere during wood combustion in a stove-fireplace with accumulation (SFA). The first part of the conducted study includes the comparison of combustion parameters of beech wood characterized by varying qualities. The second part encompassed testing different variants of control of the SFA operation. Two signals: the volume of oxygen (O2) and carbon monoxide (CO) emission were used in the first version of developed controller. These signals were coupled with upper air, bottom air and rear air dampers, controlling the opening and closing of the air throttles depending on the pre-set boundary parameters (minimal set content of oxygen in exhaust gases and the maximal set content of carbon monoxide). The studies conducted so far have confirmed the possibility to reach the exploitation parameters required by the BImSchV 2 and Ecodesign standards.
