Case Study:

Replacing bag filters with filter cartridges solved emission problems at Calucem d.o.o.

Location: 

  • CROATIA

Operation:

Cement plant: Calucem D.O.O

Dust type:

Calcium Aluminium Cement

Problem:

  • At Calucem d.o.o. the Scheuch filter bags caused various problems.
  • Due to very limited space in the collector, the filter bags had to be installed horizontally. However, the horizontal installation eventually caused the filters to bend/fall down into the collector decreasing the filtration efficiency.
  • The plant consequently experienced very high dust emissions: 47 mg/m3  

Solution:

  • By installing shorter Clean Side Removal Cartridges instead of filter bags, the lenght of the filters was reduced from 1125mm to 800 mm solving the baghouse size issues
  • The shorter filters could be installed vertically
  • Despite installing shorter filters, the filter area was increased from 22m2 to 100m2 per baghouse due to the pleated technology

Advantages:

  • By installing pleated filter technology with more filter media area in the existing baghouse, the baghouse capacity at Calucem d.o.o. was increased
  • Improved dust collection performance resulted in emission levels decreasing from 47 mg/m3 down to only 4 mg/m3

Advantages – confirmed by customer:

Calucem d.o.o. confirms that the following advantages has been obtained by installing shorter Clean Side Removal Cartridges

  • Baghouse capacity was increased by almost 5 times
  • Problems with filters bending/falling into collector solved
  • Emission levels decreased from 47 mg/m3 down to only 4 mg/m3
