Gas cooler

When per­form­ing ex­haust gas clean­ing in the ce­ment and other in­dus­tries, the ex­haust gases need to be cooled down prior to start­ing the clean­ing process. Build­ing on many years of process tech­nol­ogy ex­per­tise, Scheuch gas-con­di­tion­ing tow­ers pro­vide ex­cep­tional ef­fi­ciency thanks to their op­ti­mal in­stru­ment-based de­sign and lay­out com­bined with an adapted con­trol con­cept. Gas cool­ing in­volves cool­ing ex­haust gas by in­ject­ing very fine wa­ter droplets into the hot stream of ex­haust gas, whereby the evap­o­ra­tion process with­draws heat and achieves the de­sired tem­per­a­ture for the sub­se­quent ex­haust-gas clean­ing. As well as a de­fined con­trol con­cept, it is cru­cial for op­er­a­tional safety that the wa­ter droplets are uni­formly at­om­ized and flow evenly through the evap­o­ra­tion sec­tion. Two-com­po­nent com­pressed-air noz­zles or one-com­po­nent high-pres­sure noz­zles are used in or­der to ef­fi­ciently dis­perse the cool­ing wa­ter. The pre­ferred di­rec­tion for ex­haust gas flow is ver­ti­cal. De­pend­ing on the ap­pli­ca­tion or plan­ning re­quire­ments, the ex­haust gas flows from the top down or from the bot­tom up.
