By oxidizing the sulfur to Sono reacting lime (lime) and the oxidation-reduction of sulfur from the waste gas stream of (calcining furnace) it is removed from the pre-heater exhaust gas stream. The method is suitable for use in the cement (cement) production plant generated during the combustion of fossil fuels, the sulfur dioxide in the waste gases is used for heating in the step. It comprises a combustion air supply source, such as; (clinkering furnace 3); wherein the device for carrying out the process is multi-stage preheater (1) is in the upright position, and Sono (2 calcining furnace) and the furnace clinker. The multi-stage preheater (1) are each gas, and a plurality of line-cyclone gas solids separator (10, 11, 12, 13), an outlet 22 for separated gas connected with the accompany the cement material inlet (21) and and a solid outlet for the separated (23). An outlet 23, the container 20 with the preheated cement raw material powder (raw meal) yudongyong inlet 23 connected to the end of the calcination playing the cyclone (13). The clinker furnace 3 is supply end; in rotation with (41 feed end) and outlet end (42); and (40 rotating kiln), the outlet end has a combustion zone.
