Claims (8)

1. Method for producing pellet products from Slurry which has been absorbed in separation. The sulfur is released from the gas from wet combustion of limestone-gypsum at It consists of the procedure of a. Slurry absorption containing gypsum taken out of the sulfur separator. from the gas from wet combustion of limestone-gypsum intensification; Coal from a coal-fired kiln and with clay or lime mortar to form the mixture c. The compaction of the mixture is determined using a compacted form. D. The resulting compressible product is then cured in the reaction chamber. with part of the gas separates the sulfur which is saturated with water due to the separation of sulfur from the gas from Combustion using wet process of flow-through limestone gypsum. Therefore, pelletizing is produced. 2. Claim 1 method, where the compressed mixture is incubated in the reaction chamber for three days. 3. Claim method 1 where the compressive strength of the pelletizing product is 128 kg/cm2 - 132 kg/cm2. 4. Claim 1 method, where the hardness of the slurry in step (a) is maintained at 30 - 60% by weight. 5. Method for producing pelletizing products from by-products of sulfur separation. From the wet process combustion gases of limestone gypsum consisting of step a. Intensified lime-gypsum wetting b. This concentrated slurry kneading, which mainly consists of gypsum, is combined with coal ash and mortar or lime to form a mixture and compress this mixture. at designated c. and then solidify this extruded product by drying as well. Unsaturated hot air is produced by using heat taken from combustion gases and by adding water to the heat recovery process. Therefore, pelletizing products are produced. 6. 1.20 7. Claims-based method 6 where the Slurry ratio Coal ash and lime are in the range of 30:60:10. 8. The method according to claim 5 also consists of removing the released air from Drying of compressed hot air saturated mixtures with water is used again.
