FIELD: camping and farmsteads. SUBSTANCE: oven includes separable combustion chamber which is put on separable column-ash collector. Combustion chamber comes in the form of lattice basket made of widely spaced bars placed in air jacket between this basket on one side and four solid sheet vertical walls mounted on frame and separable solid sheet bottom plate of combustion chamber located near fixed stationary lattice bottom on the other side. Air jacket freely communicates with atmosphere through 19 slit-shaped windows with thickness in the order of 10.0 mm and total length of 4600.0 mm for air suction along entire extent of each rib of frame of combustion chamber. Air jacket is area of after-burning of combustible fractions of smoke. When solid sheet bottom plate is removed area beneath stationary lattice bottom is upper half of chamber where fire is built in combustion chamber. Combustion chamber has burners arranged one above another at several levels. Each burner, except upper and lower burners, is formed by pair of one front and one rear inseparable mobile bars lying on left and right side fixed bars of lattice basket. Size of burner can be altered thanks to displacement of its two mobile bars. EFFECT: enhanced efficiency, universality and convenience of oven. 5 cl, 2 dwg
