Abstract：
 The invention supplies a circular eddy flow thick/thin coal dust burner that refers to an eddy flow coal dust burning device. The invention set a splitter plate that separates the primary air main to up and down thin/thick coal dust conduit in the primary coal dust air main. A reducer is used to flare out the coal dust air current in the thick coal dust conduit. The bottom of the reducer forms a wedge type with the splitter plate. A fixed eddy flow vane is set in the thin coal dust conduit at the bottom of the primary air main. And the active and modified eddy flow vane on which has rolling body with cam slot channel on its surface is set in the secondary air main. The invention could effectively reduce the release of carbon x-oxide from the coal dust burner, while not obviously increase the carbon content of the fly ash. And it solves the problem of under-load inflammation, stably burning and reducing the resistance and abrasion of the primary air main while burning the low-volatile coal dust. Thus, the useful life and the burning device performance cost of the burning device is increased.
