Description

Well-known baking two-chamber furnaces with stationary hearths and channel heating.

According to the invention, in the proposed device of a similar furnace first. the duct passes between both chambers and is adjacent to two vertical channels provided with gates for the possibility of heating the chambers together and alternately.

In FIG. 1 shows a longitudinal section of the furnace; FIG. 2 is a vertical section through the furnace; FIG. 3 is vertical (section along the chambers and Fig. 4 is a horizontal section.

The proposed bakery oven consists of a coal furnace 1 located between baking chambers 2, 3, of which the bottom 2 is shorter than the top 3. Under the furnace 1 there is a blower, which enters the air through the doors placed on the sides and channels covering the furnace, thanks to what the air enters under the grate is somewhat heated. In addition, air is supplied to the grate through side channels located along the entire furnace parallel to the first main gas duct 4 of the furnace. These channels are blocked from the outside by doors and serve to make the most of the heat.

By blocking the channels with the doors, it is possible to change the amount of air entering the furnace through one or another channel, and, thus, to set the required combustion mode.

When baking bread, either the top 3 or bottom 2 chambers can work, or both at the same time. In the first case, the hot gases from the furnace 1, the passage through the main duct 4, branch out at the end of the furnace and through the vertical channels 5 pass into the upper horizontal chimney 6, from where into the flue pipe 7.

In the event that the baking is done only in the lower chamber, both the gates 8 are closed and the gases go down through the vertical channels 5, then through the channels 9 and 10 enter the chambers 11, from where — through the inclined channels — into the flue pipe / i2. Channels 7 of the chimney 12 behind the faucets 13, 1-4 are merged into one

common channel. Using the hooks 8, 13, 14, it is possible to regulate the temperature of heating in the lower and upper chambers, which makes it possible to bake different types of bread in them at the same time as both chambers 2 and 3.

Full use of the furnace can be achieved only with the simultaneous operation of both chambers. In this case, the hot gases, circling around the lower chamber 2, give off heat, but once in the chambers 11, located near the furnace, they are directed through the channels 15 along the upper chamber 3, which is heated from the sides, and out into the chimney through the channels .

The slide 13 opens fully, and the hooks 8 and. 14 is completely closed or broken.
