In this paper, the author transform the flat separator into groove separator with respect to high quantity of combustible materials in fly ash in a spreader\|stocker\|fired travelling grate boiler.

This paper researched a tangential inlet enlarged diffusion square separator by the RSM and DPM model which consider anisotropic situation, analyses the distribution of axial, tangential and radial velocity in different sections, calcu-lates the separate efficiency with different diameters and particle tracks.

An experimental study was conducted of the separation efficiency and separator resistance of a horizontal heat exchange mode based square separator under different air speeds and inlet concentrations.

Based on cold test, a patent square separator with particle accelerating inlet was developed by Tsinghua University.

Neural network optimization for square cyclone operation;

In order to research on the square cyclone’s structure parameters influence on its performance, gas flow in square cyclones with different parameters was predicted using Reynold stress model(RSM).

Detailed experiments were carried out to study of the behavior of square cyclone.
