Effects on process and control for ETA Cooler
Lower number of strokes in ETA Cooler reduced wear
even clinker distribution over the the cooler width
Variable retention time of the clinker over the cooler width
Comparison Grate cooler – ETA Cooler
ETA Cooler
•Each lane is driven separately
•Max. stroke length 400mm
•Individual stroke lengths for each
lane possible

Transport capacity replaces grate speed!
Transport Capacity: distance covered by all lanes during
defined time
Maximum transport capacity:
Max. stroke length x number of lanes x number of strokes
Actual transport capacity:
Actual stroke length x number of lanes x number of strokes
Indicated in % of maximum capacity
Transport Capacity
ETA General design and function.ppt
22
篦板速度替换为输送量 !
输送量: 某段时间内全部列向单元经过的路程
最大输送量 :
最大行程 x 列向单元总数 x 冲程数量
实际输送量 :
实际行程 x 列向单元总数 x 冲程数量
显示数值:相当于最大输送量的 %。
输送量
ETA General design and function.ppt
23
Example
Maximum capacity:
Number of lanes: 6
Maximum stroke length: 400mm
Maximum number of strokes: 6/min
Resulting max. capacity: 14400 mm/min
(= 6 x 400 x 6)
Actual capacity:
Stroke lengths: 150mm (Lane No. 1 + 6)
300mm (Lanes No. 2 – 5)
Number of strokes: 4/min
Resulting actual capacity: 6000 mm/min
(= [2 x 150 + 4 x 300] x 4)
Resulting actual capacity: 41.6% of maximum capacity
Transport Capacity

例如
最大输送量 :
列向单元总数 : 6
最大行程 : 400mm
冲程数量最大值 : 6/min
最大输送量得数 : 14400 mm/min
(= 6 x 400 x 6)
实际输送量 :
行程: 150mm (1号和 6号列向单元 )
300mm (2到5号列向单元 )
冲程数量 : 4/min
实际输送量得数 : 6000 mm/min
(= [2 x 150 + 4 x 300] x 4)
