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

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
