With its new hot-gas fil­ter tech­nol­ogy, the pi­o­neer in air pol­lu­tion con­trol is re­veal­ing the fu­ture of ex­haust gas clean­ing and de­dust­ing. This opens up com­pletely new sys­tem con­cepts for eco­nom­i­cal and en­vi­ron­men­tally friendly dust sep­a­ra­tion and pol­lu­tant re­duc­tion. One of the many ad­van­tages is the high tem­per­a­ture re­sis­tance of the can­dle fil­ters. While con­ven­tional bag fil­ters with fab­ric me­dia reach their lim­its at process tem­per­a­tures of 260 °C, for hot-gas fil­ters and their ce­ramic fil­ter el­e­ments, even 500 °C is no prob­lem. Re­gen­er­a­tion is per­formed based on the proven im­pulse clean­ing sys­tem, which can be used to achieve ex­tremely low dif­fer­en­tial pres­sures. Of­ten, the tem­per­a­ture of the dust-laden ex­haust gas is in the range be­tween 300 °C and 500 °C, tem­per­a­tures at which en­ergy re­cov­ery is ad­vis­able. Thanks to the dust-free ex­haust gas pre­sent here, more cost-ef­fec­tive and op­er­a­tionally safe heat ex­chang­ers can be used. En­cour­aged by the suc­cess of the new hot-gas fil­ter, Scheuch re­searchers are al­ready work­ing on how to de­velop the tech­nol­ogy fur­ther to lower in­vest­ment and run­ning costs. The fo­cus is on achiev­ing the most com­pact de­sign pos­si­ble com­bined with a high level of op­er­a­tional safety. Branch­ing off from that, the team is also work­ing on new sys­tems to re­duce pol­lu­tants: For ex­am­ple, sys­tems that com­bine fil­tra­tion and cat­alytic den­i­tri­fi­ca­tion in a sin­gle process step and in­crease the pos­si­ble ap­pli­ca­tion tem­per­a­tures to 1,000 °C.
