The invention relates to an injector incomplete premix burner and may be used in household furnaces and furnaces of different technological destination, kettles and driers.The injector incomplete premix burner, according to the first variant, contains a body (1), a nozzle (2) and a premix chamber (4). The body is made in the form of a horizontally placed parallelepiped, one face of which is muffled, and into the open face there is placed the nozzle. Into the body there is inclinedly, installed a plate (3), one edge of which is fixed onto the upper base of the body from the end of the open face, and the free edge is placed with clearance about the muffled face, constituting 1,5...2,0 from the width of the body base. The clearance between the free edge of the plate and the lower base of the body is determined from the relation D>=Pidg2/4a, where D is the distance between the free edge of the plate and the lower base of the body, dg is the diameter of the neck of the classical injector of equal power, a is the width of the body base. The fire holes (6) are made in the upper base of the body. The plate is made concave in the region of fixation to the body upper base with the radius of curvature equal to (1,7...4,3) dg, where dg is the diameter of the neck of the classical injector of equal power.The gas burner, according to the second variant, contains a body (1), a nozzle (2) and a premix chamber (4). The body is made in the form of a horizontally placed parallelepiped, one face of which is muffled, and into the open face there is placed the nozzle. Into the body at an angle with the lateral walls of the body there are installed symmetrically placed about the longitudinal axis of the body two plates (3, 7), each of which having one edge fixed to the lateral wall of the body from the end of the open face and the free one is placed with clearance, constituting 1,5...2,0 from the height of the lateral wall of the body, about the muffled end. The clearance between the free edges of the plates is determined from the relation D>=Pidg2/4a, where D is the distance between the edges of the plates, dg is the diameter of the neck of the classical injector of equal power, a is the height of the lateral wall of the body. The fire holes (6) are made into the lateral walls of the body. The plates are made concave in the region of fixation to the lateral wall of the body with the radius of curvature equal to (1,7...4,3)dg, where dg is the diameter of the neck of the classical injector of equal power.
