FIELD: heating. ^ SUBSTANCE: oven includes furnace, afterburner, heat exchanger and flue gas removal pipe, which are connected to each other with gas duct channels. Afterburner is located in the furnace and made in the form of horizontal cylindrical tube and equipped with vortex formation device and air duct made in the form of additional pipe located along the pipe axis of afterburner. Afterburner pipe closer to front wall of furnace is equipped with longitudinal slots so that blades are formed, and vortex formation device is made in the form of bent blades; at that, each of blades is twisted with smooth increase of angle of 0 to 35 degrees in the direction towards front wall of the furnace, and hole of the pipe is plugged from the end face. There described is air duct of afterburner pipe and heat exchanger for this oven. ^ EFFECT: simplifying the oven design and increasing fuel combustion efficiency. ^ 4 cl, 3 dwg |
