Description

Continuous baking ovens with a chain conveyor in a furnace chamber divided by a chimney in height into two parts, of which the upper one is blocked by a steam cap, are already known.

A feature of the proposed furnace is that chimneys in it are located across the longitudinal axis of the conveyor and consist of two parallel channels for the opposite direction of gases through them.

FIG. 1 shows a longitudinal section of the proposed furnace, and FIG. 2 - cross section.

The bakery oven has a furnace 7, which is located in the back of the oven. Chimneys are the inlet channel 2, horizontal channels 9 and 10, connecting vertical channels 4, 5 and b and branch channel 3. The chain conveyor 7 is located in the furnace chamber 8, divided in two parts by a pair of zigzag chimneys located across the longitudinal axis of the conveyor 7. Each pair of chimneys consists of two parallel channels: the bottom one - 9 and the top one - 70, connected by vertical channels 6.

The furnace is as follows:

From the furnace 7, the flue gases enter the inlet channel 2, from which through the vertical channels 4 they enter the lower channels 9, where they move in two parallel streams. From the channels 9, the gases through the vertical channels 6 enter the upper channels 70, where they also move in two parallel directions in the opposite direction with respect to the channels 9. The flue gases, the passage through the channels 9 and 70, release their heat through the walls of the channels to the furnace chamber 8, creating the necessary temperature there. From the channels 70, the gases through the vertical channels 5 fall into the exhaust channel 3, from where they are discharged to atmospheres through the chimney (not shown in the drawing).
