High Efficiency Cyclone definition
High Efficiency Cyclone means any cyclone type collector of the 2D-2D or 1D-3D configuration. The 2D-2D design for small diameter cyclones is set forth in Agricultural Handbook 503, U.S. Dept. of Agriculture, Cotton Ginners Handbook, 1977 Edition, pages 81-84. The 1D-3D design for small diameter cyclones is the Texas A & M University long-cone cyclone design. Design specifics of this type of cyclone are set forth in Figure 6 of the article titled, "Air Utilization", by E. P. Columbus, which was presented at the Cotton Ginners Shortcourse which was held on July 27- 31, 1987 at Stoneville, Mississippi.

High Efficiency Cyclone means any cyclone type collector of the 2D-2D or 1D-3D configuration. These designations refer to the ratio of cylinder to cone length, where D is the diameter of the cylinder portion. A 2D-2D cyclone would exhibit a cylinder length of 2 x D and a cone length of 2 x D (90 percent collection efficiency). A 1D-3D cyclone would exhibit a cylinder length of 1 X D and a cone length of 3 x D (95 percent collection efficiency).
