Title of the articleDependence of efficiency and thermal streams in fire chambers from the direction of a twist of air in torches
Abstract.Modes of operation of the boiler TGM-84B with the first tier of burners for small angles of twist peripheral air is preferable to increase the efficiency in comparison with modes at large angles of twist. Small angles of twist of air at the first tier of burners helped to raise the amount of heat transmitted to the superheater. Effect of the air excess factor for efficiency, compared the influence of a twist in the air of the first tier of burners, it affects less. Increasing the exhaust gas temperature of up to 10? C also has an effect in at least a reduction in efficiency, as compared with the increase of the . twist angle of from 20 to 45 Effect of changes in the angle of twist of the two air burners second layer affects the efficiency in the least, as the quantity of air at twisting half, compared with simultaneous twist air burners of the first tier. . In general, higher efficiency when changing the twist due to the fact that when the twist changes the configuration of the torch heat absorption and redistribution by heating surfaces toward a greater proportion of the heat input into the superheater.
Keywords.copper, temperature, fire chamber, torch, excess of air, twist, torch, thermal streams.
