Claims (1)

Claim A vortex furnace containing a vertical shielded prismatic combustion chamber with a cold funnel and a protrusion with upper and lower slopes located on the rear wall, pulverized coal burners located on the front wall of the combustion chamber below the protrusion, secondary blast nozzles located at the mouth of the cold funnel, and lower and the upper nozzles of the tertiary blast located on the rear wall of the chamber, respectively, lower and higher than the protrusion, which is supported by the fact that, in order to increase the economy and reliability, The tank is equipped with additional pulverized coal burners placed on the front wall with the same slope as the main burners and above the upper point of the protrusion at the same distance from it as the 5 main burners from the edge of the cold funnel, and an additional protrusion placed on the back wall on exit from the combustion chamber, the upper and lower slopes of which are made with the same slope as similar slopes of the main protrusion, the main protrusion being located at a distance from the bottom of the combustion chamber equal to 0.23-0.4 of the height of the chamber, and the upper slopes the protrusions are inclined to the horizon with a sub-angle of the same angle as the rear slope of the cold funnel. ¹⁰ 5-B 7 7 / / in Aa FIG. 3 Compiled by V.
