Description

one

The invention relates to furnaces of steam generators operating on gaseous, liquid and solid fuels.

Tonpchnye chambers, separated from the cooling chamber by non-casuals, are known with counter-flow (1m thin and air soils, the last of which are mounted obliquely

DOWN 1.

The disadvantage of such furnaces is the low intensity of the heat-transfer and combustion processes due to the aerodynamic instability of the flow and shutdown of individual burners, detrimental removal of air and fuel from the torch root to pinch. This is due to the small relative diameter (caliber) of the nozzles and the large relative distance (in calibers) between the centers of the output sections of opposite soils, resulting in a meeting of the jets beyond the limits of their Initial trainings, which is ineffective from the point of view of heat exchange and combustion.

The purpose of the invention is to provide an intensification of heat exchange and combustion processes in H: 04, HOii chamber.

This is due to the fact that the walls on which the air units are hardened are placed one from another by a distance equal to (4-7) d, the distance between the centers of the exit sections of the air soyles and pods (6-9) d, the distance between the centers of these coil- (6-I0) d, and

the opposite ones are (3-5) d, and in the latter the centers of the output sections are separated from the intersection of the nozzle axes at a distance of (3-4) g /, where is the lateral diameter of the airfoil.

Pa (|) Figure 1 shows a thin chamber, a vertical section in flat air jets; on fng. 2 - the same plan view.

In the housing I of the combustion chamber, air seats 2 are installed, which have a round or ellptic shape. Under the N-them on the walls of the housing of the furnace chamber fuel fuel cells 3 or soy are fixed for adding thin-air mixtures.

The camera works as follows.

The air on the burner is supplied to the combustion chamber through the seatlone 2. and the fuel or the air-to-air mixture is fed through soybean 3 to the zone of intensive massaging.

This camera contains a body with a node, located on its opposite walls and counter-directional thin and air soils. the latter of which are set obliquely downwards, except that. in order to provide intensive protesa transfer of heat exchange and gore, 11, walls, on which are crowned with Sonla, are separated from one another. The stumps are equal to (4-7) s /, the distance between the central sections of the output sections of air nozzles of the sub- (6-9) , the distance between the centers of these nozzles is (6 - 0) rf, and the opposite ones are (3-5) d, and y after / igplent the output sections, this distance from the intersection of the axes of the nozzles at a distance of (3-4) d, where d is the inner diameter of the air nozzle.
