Potbelly stove Fire "Battery" with secondary combustion of furnace gases, steel 4mm

The principle of operation of a furnace firebox with a system for secondary combustion of furnace gases. The supply of primary air for combustion occurs through the grate, while smoke containing the smallest particles of unburned fuel rises higher into the combustion chamber. To achieve complete combustion of firewood, “secondary combustion” technology is used, when additional oxygen is supplied to the second chamber of the furnace through secondary air ejectors. Secondary air, passing through the channels between the walls of the housing and the hot combustion chamber, heats up and enters the combustion chamber through special holes in the deflector tube. Visually, the entire secondary combustion chamber is engulfed in flames. Thanks to this, not only the unforgettable effect of a living fire is achieved, but also a suspension of unburned fuel and carbon monoxide is burned. The double afterburning system allows you to reduce the amount of harmful emissions into the atmosphere and, most importantly, retain more heat in the house. Technical characteristics: metal thickness? 4 mm. Overall dimensions: width? 350 mm; height ? 600 mm; depth (furnace 460 mm) (dimensions 560 mm); weight? 45 kg; Heated room area up to 60 sq.m.? chimney 108 mm (for a standard 110th pipe); power range? 4-9 kW; combustion chamber volume? 27 dm3; furnace heating surface? 1.1 m2; efficiency of at least 80%. The well-known potbelly stove is a metal structure designed for internal heating of premises. We managed to improve the performance characteristics of the potbelly stove by changing the classic design and at the same time maintaining its positive qualities: fast heat transfer, small size and ease of installation. The great advantage of this model is the presence of a hob on which there are two burners, which allows you to cook food and boil water without any effort. A plate is welded inside the upper part of the stove. Because of this, hot furnace gases travel a longer path and leave more heat in the furnace. The heat transfer of the furnace body has also increased, as the area of ​​metal surfaces inside has increased. The stove is also equipped with a rotary damper (damper) located at the head of the chimney. The gate acts as a draft regulator, that is, it acts as a control valve. By turning the damper handle, you can increase or decrease the cross-section of the smoke channel, thereby adjusting the intensity of combustion in the firebox. Another feature of the stove is the very tight fit of the doors to the body. This is ensured by the internal door liner, which prevents air leaks, and by the handles (which, at the same time as latches, fit into hooks made in the form of wedges). Assembly is carried out using continuous welded seams inside the furnace, which eliminates air leaks and disruption of the geometry of the structure. The outside of the furnace is equipped with a convection radiator of 12 sections, which allows heating a fairly large room in a short time. The temperature of the furnace gases should provide a sufficient draft reserve, but for this you need to correctly position the head of the chimney. It should not fall into areas of high pressure, but it is better to bring it above the roof ridge. Operating the stove The algorithm for kindling and further using the potbelly stove is quite simple. First, melt it with small wood chips, paper, etc. If this does not work out right away, you can remove the lid of the cooking hole and put burning paper under the pipe, then close the lid. The combustion level is maintained by adjusting the ash pan door. When the temperature in the room rises to the desired level, place 3-4 logs as thick as your hand and 30-40 cm long in the oven on the coals and then close the doors tightly. This sharply reduces the access of air inside, which leads to the transition of combustion to smoldering. Thus, firewood can smolder for several hours, depending on its moisture content, thickness and origin. At this time, the oven will provide heat evenly. And if the house has good thermal insulation, even in decent frosts you can comfortably stay in such a house for a long time.
