- Abstract
In the framework of this paper new approaches to the magnesite waste decreasing and treatment are presented. The principal producers of the magnesite waste are rotary and shaft furnaces. For the rotary furnaces the new charging device was developed by which the charge layer thickness was increased more than two times. By this measure 25 % flue dust quantity decreasing was achieved. Further flue dust decreasing was achieved by the increasing of the furnace intensity. For this purpose radial burner was developed. Burner arrangement enables effective combustion of the secondary air. Flue dust decreasing in the shaft furnaces was achieved by sintering temperature homogenisation through the furnace cross section. By application of the new immersed burner significant flue gas volume decreasing was achieved. Flue dust thermal treatment enables its revaluation. For this purpose compact thin layer, furnace, microfluid and high revolution rotary furnaces were developed. Their verification proved high availability and effectiveness.
