CUS­TOMIZED TECH­NOLO­GIES FOR EVERY AP­PLI­CA­TION

Our com­pre­hen­sive range of bag fil­ter prod­ucts with the tried-and-tested im­pulse clean­ing sys­tem and mod­u­lar fil­ter model ranges can be pre­cisely adapted to the cus­tomer's in­di­vid­ual re­quire­ments ac­cord­ing to their process tech­nol­ogy and struc­tural con­di­tions. Vol­u­met­ric flow from 100 to over 3,000,000 Bm3/​h can be achieved for de­dust­ing, prod­uct sep­a­ra­tion and gas clean­ing in the dif­fer­ent in­dus­tries re­quir­ing these processes.

Scheuch ap­plies its decades of ex­pe­ri­ence to the fil­ter, from the plan­ning phase to com­mis­sion­ing, which is re­flected in count­less com­pleted plants. The re­sult is min­i­mal pres­sure loss, achieved through op­ti­mum fil­ter in­flow and out­flow and by us­ing the ap­pro­pri­ate fil­ter bags. Scheuch en­deav­ours
to pro­vide every cus­tomer with the most eco­nom­i­cal and ef­fi­cient so­lu­tion, in­di­vid­u­ally adapted to their re­quire­ments: This forms the heart of its phi­los­o­phy.

THE PER­FECT DE­SIGN MAKES THE DIF­FER­ENCE

or­ward-think­ing tech­nol­ogy for flue gas de­dust­ing. De­sign­ing elec­tro­sta­tic pre­cip­i­ta­tors for flue gas clean­ing af­ter com­bus­tion processes re­quires a great deal of process ex­per­tise, as a huge num­ber of pa­ra­me­ters need to be taken into ac­count. On the one hand, the ash com­po­si­tion and the flue gas pa­ra­me­ters, which have a di­rect in­flu­ence on the sep­a­ra­tion ef­fi­ciency, must be con­sid­ered, with­out ne­glect­ing the gen­eral con­di­tions of the process on the other hand. It is only by cor­rectly eval­u­at­ing the ad­van­tages and dis­ad­van­tages of the var­i­ous tech­nolo­gies and their com­bi­na­tions – with down­stream heat re­cov­ery sys­tems, for ex­am­ple – that the ideal cus­tomer-spe­cific so­lu­tion can be achieved.

AD­VAN­TAGES OF ELEC­TRO­STA­TIC PRE­CIP­I­TA­TORS

• High degree of separation, even with fine dust
• Largely impervious to load fluctuations,
  flying sparks, overheating and sporadic dew point shortfall
• Low operating costs thanks to low pressure loss
  and low maintenance costs
• Long service life and high availability
• Highly suited to retrofitting in existing plants

HOT STUFF

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.

SCHEUCH XMER­CURY SEP­A­RATES MER­CURY IN PASS­ING STREAMS

Scheuch xmer­cury helps sep­a­rate mer­cury from the com­bus­tion process in a straight­for­ward and process-safe way. The in­no­v­a­tive Scheuch sys­tem means mer­cury-laden gas can be bound to ac­ti­vated car­bon be­fore be­ing safely dis­charged.

To re­duce mer­cury emis­sions, Scheuch has de­vel­oped a tech­ni­cal in­no­va­tion to­gether with the com­pany A-TEC and the W&P Group: the xmer­cury split pre­heater sys­tem. The re­sults are as­ton­ish­ing.

FACTS:

• Up to 80 % reduction in mercury emissions
• Minimum costs for sorbent due to low consumption
• Low energy costs (no additional heat loss)
• Low gas quantity (3–10 % of the total quantity)

Process-integrated installation

The re­quire­ments for in­te­grated ex­haust gas clean­ing clearly show that a given plant con­fig­u­ra­tion can­not be ap­plied equally to every ce­ment plant be­cause of plant-spe­cific process pa­ra­me­ters. In its ca­pac­ity as an ex­pert provider of NOx ex­haust gas re­duc­tion so­lu­tions, there­fore, Scheuch's aim is to work with the cus­tomer in or­der to de­velop the right process and pro­vide a turnkey in­stal­la­tion – all from a sin­gle source. In pur­su­ing this aim, we look at all kinds of tech­nolo­gies from the out­set in or­der to en­sure that we are cre­at­ing the very best so­lu­tion for every ap­pli­ca­tion case.
