Fire chamber and combustion chamber of the furnace for pyrolitic combustion of wood material consists of a reservoir loading chamber (1) a regular octagon-shaped, created as a weldment of metal burnts, to ensure natural heated air flow and radiant heat from the fireplace and systematic heat and air flow off around the inner surface of this chambers and the combustion chamber (2) and between such spaces is located nozzle (3), which is also located at the bottom the reservoir loading chamber (1), is provided with grooves (4) in the back of the nozzles for disabled access preheated secondary air supply, where sectional areal dimension of the groove (4) correspond to sum of the sectional areal dimensions of transverse holes (6), located in the side grooves (7) and flow into nozzle mixing area, while the total cross-sectional areal dimension of the left and right longitudinal side grooves (7) of nozzle is the same as cross-sectional areal inner dimension of pipe of secondary air inlet to the inner shell of heat exchanger, further is equipped with a center mixing hole (8), in vertical cross section preferably trapezoidal shape and in the horizontal cross section preferably rectangular shape, which flows into the combustion chamber (2). The nozzle (3) is preferably formed of two each other mirror identical parts, whereby in cross section has a trapezoidal shape. |
