PM-TECHNOLOGIES
KILN AND PREHEATER PLANT OVERVIEW
OPTIMIZATION OF KILN PLANTS
overview and activities
OPTIMIZATION OF KILN PLANTS
BOTTLENECK-EVALUATION OF KILN AND PREHEATER PLANT
Pyro-process
- thermal conditions in kiln and preheater
- operation of kiln inlet, kiln riser and calciner
- Cl-bypass and meal input positioning
Preheater cyclones
- pressure loss
- separation efficiency
- thermal efficiency
TAILOR-MADE SOLUTIONS, BASED ON THE INDIVIDUAL DEMANDS OF OUR CUSTOMERS!
- increased clinker output
- improved energy consumption

- modification of cyclone chamber, entrance and spiral
- re-dimensioning of dip-tubes and riser ducts
- installation of guide vanes HURRITEC GV
ADVANTAGES
- reduction of pressure drop up to 50%
- higher gas rate/performance at same pressure drop
- improved separation efficiency
Retro-Fit or replace cyclones ?
OUR TAILOR-MADE SOLUTIONS ALLOWS FOR
BEST POSSIBLE UTILISATION OF EXISTING EQUIPMENT!
HURRITEC GV GUIDE VANE
overview and activities
OPTIMIZATION OF KILN PLANTS
TECHNICAL FEATURES
- more effective flow through the cyclone and dip tube
- optimized gas velocities
- easy to retrofit in existing cyclones
ADVANTAGES
- reduction of pressure drop up to 50%
- higher gas rate/performance at same pressure drop
HIGH ENERGY SAVINGS ARE POSSIBLE FOR NEARLY EVERY CYCLONE !
(preheater plants, grinding plants, clinker cooler cyclones, etc.)
PRECALCINER
overview and activities
OPTIMIZATION OF KILN PLANTS
TECHNICAL FEATURES
- evaluation of fluidic dynamics (CFD)
- prolongation of ascending and descending ducts
- installation/modification of mixing and combustion chambers
- integration of burners for firing of secondary fired fuels
- optimization and adjustment of meal feeding
ADVANTAGES
- increase of retention time
- increase of alternative fuel rate and secondary burning
- best operating and mixing conditions for good burnout
2-STEP MEAL CHUTE SYSTEM
overview and activities
OPTIMIZATION OF KILN PLANTS
- partial meal quantity of 2nd last cyclone stage (700°C) is fed well dispersed into the hot kiln gases directly above kiln inlet
- volatile impurities (SO3, Cl) condense on the cold meal
- substantial reduction of build-ups at high SO3-content
- more stable and efficient kiln operation with alternative fuels
TECHNICAL FEATURES & ADVANTAGES
UNIQUE DESIGN FOR ACCESSORIES
meal splitter pendulum flap splash-box
KILN INLET & CHLORINE BYPASS SYSTEM
overview and activities
OPTIMIZATION OF KILN PLANTS
KILN INLET
- optimized kiln inlet design by new housing
- enlargement of kiln screen and critical cross-section
- kiln sealing pneumatically operated
Reduction of kiln gas velocity (pressure drop)
Reduction of dust re-circulation
CHLORINE BYPASS SYSTEM
- positioning of gas extraction on low-dust side
- cooling in multi-stream mixing chamber
- 1 or 2 stage quenching system
High and fast mixing quality
Stable operation conditions
TECHNICAL FEATURES
- 1 HURRITEC DT instead of two conventional cyclones
- guide vanes HURRITEC GV for lowest pressure drop
- double dip tube cyclones lined with special wear resistant lining
RESULTS
- highest separation efficiency > 98%
- low pressure drop for energy saving operation
- reduced system dimensions
- no reasonable wear in HURRITEC DTs and fan after three years of operation
