Description

Groups of steam and mechanical nozzles are installed in the water firing chamber and in the same flue space, the axes of which lie either in intersecting or parallel planes, which contributes to a better atomization of the spill and mixing of the air flows to the guns, improving the thermochemical reaction. /.

In FIG. Figure 1 shows a vertical section of the oil-burning furnace of a horizontal liquid-tube boiler; FIG. 2- horizontal section of it; . 3-vertical section of the oil furnace of a vertical water-tube boiler; 4 horizontal section of it.

In the oil furnace (Figs. 1, 2), the mechanical nozzles D are installed in two horizontal rows, thus achieving the simultaneous use of the manpower of the steam cfpyvi installed at the bottom of the burner nozzle 2 for additional pulve {) from 4 co-sprayed fuel nozzles, as well as better mixing of the streams air flowing to the steam and mechanical nozzles, and mixing it with the nozzle plugs of both types. The fuel inlet of the micro nozzles 3 from the side of the boiler easily formed at a high location and the tunnel 4 accessible for servicing allows the use of even more power from the jet of steam nozzles. The arrangement of the mechanical nozzles 3 on the side walls of the furnace simultaneously contributes to a uniform and fairly rare location. usually numerous mechanical nozzles, owing to their small throughput.

With oil furnaces for vertical boilers (Fig. 3, 4), due to the absence of the ash basement .5 (Fig. 1), steam nozzles 2. Are installed densely below the bottom of the furnace, and above them are located in one or more rows Mechanical nozzles 1, placed in the abundantly supplied bottom, back and partly from above radiant heat section of the furnace npocTpaHCfBa, and a short wide torch of mechanical nozzles 1 will be bent on the indicated sides with a longer torch of steam nozzles 2. On the back wall there are mechanical nozzles 3, and on the side 3 which by placed at an angle; because the extreme sections of the axis of the plumes of the steam nozzles 2, in the place of their rise to the vertical position, i.e. under conditions that are not so favorable for improving the atomization of fuel particles that have not been crushed by mechanical spraying. However, the torch of mechanical nozzles 3 and 3 encounters: high final temperatures of both the torches of the steam nozzles 2 and the air heated by them: this ensures high rates of thermochemical reactions for the combustion of coarsely sprayed fuel of the torches of the nozzles 3, 3. ensuring the supply of heated air to the nozzles 3 and 3, a duct 6 is located under nozzles 1 and 2 for supplying air. laid in the same group under the mutual inclination of the axes to each other. : j j temporary use of steam and mechanical nozzles arranged groups; pami and fuel guide streams in parallel or intersecting planes. The nozzles 1, 2, 3 and 3 may be object of the invention. Oil on the firebox, differing from one
