Assembly 108. In this particular embodiment, the cartridge assembly 108 is not surrounded and includes and/or operatively engages a coal inlet tube 210 of -11 - 201200242 or more. 8 and 9 are close-up views of various portions of the coal mill 100. Referring to Fig. 8, Fig. 8 is a view from the inside of the coal mill 1〇0 having a central coal inlet pipe 11〇, showing the cylinder assembly of the embodiment of the invention shown in Fig. 2. The coal mill, wherein the number of blades driven by the cylinder assembly is the same as the number of coal outlet pipes provided on the coal mill. Referring to Figure 9, Figure 9 is a top plan view of the cartridge assembly of the present invention disposed within the coal mill of Figure 8. Referring to Figures 10 and 11, Figures 10 and 11 disclose an embodiment in which the number of vanes 114 is less than the number of coal outlet tubes 106. In the specific embodiment of Figures 10 and 11, the number of blades is six and the number of coal outlet pipes is eight. Thus, in this particular embodiment, the number of vanes 114 can be equal to, less than, or even greater than the number of coal outlet tubes. The use of the number of leaves, its control plan, and its placement are related to several factors, including, but not limited to, the amount of coal from the individual coal outlets in the coal mill; Flame characteristics of burners connected to individual coal outlet pipes; and/or various physical and/or engineering analyses (eg, flow analysis, output analysis, etc.). With respect to the present invention, the cartridge assembly has all of the specific embodiments of two or more blades, each of which can be independently controlled or combined with one or more other blades or controlled together . As described above, a plurality of externally adjustable blades 1 14 are arranged between the classifier and the mill outlet (see Milk Figure 3, 7, 10 to and 14). In a neutral adjustment, one or more of the blades 114 of the present invention are parallel to the spiral flow of the air/coal mixture. The vanes may be adapted to each of the at least one drive or actuating device 1 16 of each vane 1 1 4 (as detailed above in -12-201200242) for individual and differential Speed adjustment to steer the air coal mixture flow path. Since the air is returned to the original state faster than the coal, the air dust per unit volume of the air flowing out of the mill is changed. This change is achieved by using a cartridge assembly 108 that supports one or more blades 114, shaft 126, and bearing assembly 128. As mentioned above, various embodiments of the cartridge assembly 108 are designed to protect at least one drive or actuating device 116 of each blade 114 from the impact of abrasive coal dust traveling through the classifier outlet cylinder (see Figure 3). . The cartridge assembly 108 can be designed for use with a mill having a central coal inlet tube or a mill with a raw coal inlet tube for side feed. In addition to the drive or actuating device 116 described above, other methods of moving the blade within the scope of the present invention include, but are not limited to, a worm driven by an external actuator. Referring to Figures 12 through 14, the various figures show various other views and/or embodiments of the present invention. In particular, Figure 12 is a cross-sectional close-up view of a cartridge assembly of the present invention wherein the cartridge assembly surrounds a central coal inlet tube disposed on the coal mill. 13 is a plan view of a cartridge assembly of the present invention, wherein the cartridge assembly is surrounded by a central raw coal inlet pipe disposed on the coal mill, and wherein the blade assembly is driven by the blade The quantity is less than the number of coal outlet pipes located on the coal mill. Finally, Fig. 14 is an isometric view of a cartridge assembly of the present invention, wherein the cartridge assembly surrounds a central raw coal inlet tube disposed on the coal mill. Changing the coal dust load per unit volume of the main air stream changes the flow of coal into each burner without changing the main air flow. The speed of the main air flow to the air/coal mixture exiting the burner fuel nozzle is extremely important in the burner's total air dispersion of -13-201200242, as both are extremely important for achieving combustion optimization. In accordance with the above specific embodiments, the present invention eliminates any potential interference or conflict between any of the drive devices present in one or more coal flow vanes and any swing valves (i.e., turrets) disposed within the upper interior of the coal mill. It will be apparent to those skilled in the art that the present invention is not limited solely to low turrets or turretless coal mills. Conversely, the invention may be adapted for use on any coal mill where it is necessary to control one or more coal flow vanes from an internal surface. In addition, the present invention can retrofit existing coal mills to allow for the systematic or individual control of coal in one or more coal outlet tubes within the coal mill by positioning one or more coal flow vanes.
