Description

(54) TOPKA

The invention relates to devices .; You need to burn fuel and can be used in thermal power plants.

Known fireboxes containing a vertical prismatic combustion chamber or with a cold funnel, in which the litters are placed

The disadvantage of these fireboxes is the enhanced thermal and dynamic effect of the torch on adjacent screens.

These drawbacks are eliminated in the top containing the vertical prismatic combustion chamber with a cold funnel, which is placed with a slope to the top of the burner L2l.

The disadvantage of these devices is low reliability due to slag ingress into the burner embrasures.

Partially indicated deficiencies are eliminated in the firebox, containing a prismatic combustion chamber with burners installed on its anti-coping front walls at the same level in horizontal rows with equal pitch and offset by half of the opposite wall opposite to the burners, and each burner is formed of

rod over the other, respectively, the feed nozzles and air mixture Cz.

However, slagging of the front walls occurs in this furnace, which reduces reliability.

The aim of the invention is to increase reliability.

This goal is achieved by the fact that the front walls of the combustion chamber

10 are formed by the connection of similar inclined skagli upper and lower vertical sections located at the same level relative to the sections of the opposite wall,

15 with the distance between the upper sections being greater than the distance between the lower ones, and the burners mounted on the latter with a slope upwards.

In the drawing there is a schematic image 20 of the proposed firebox, a longitudinal section.

The furnace contains a vertical prismatic combustion chamber 1 with burners 2 installed on its opposite front wall walls 3 at the same level with horizontal arcs with equal pitch and offset by half. burners 2 prot against the wall 3. Each burner 2 is formed by

thirty

Claims (1)

Claim A furnace containing a vertical prismatic combustion chamber with burners mounted on its opposite front walls at the same level in horizontal rows with equal pitch and offset. Half of the latter relative to the burners of the opposite wall, each burner is formed by air mixture mixtures and air, characterized in that, in order to increase reliability by reducing slagging, the front walls of the combustion chamber are formed by connected similar to sloping slopes of the upper and lower vertical sections located at the same level relative to the sections of the opposite wall, and the distance between the upper sections is greater than the distance between the Lower ones, and the burners are installed on the latter with an upward slope.
