Round Honeycomb Ceramic

Product Description
 
1. Name: Regenerative Parallel vertical lime kiln

2.Design Capacity: 70~600TPD

3.Structure & calcination method
3.1 The cross section of the lime kiln consists of 2 semicircular chambers which is connected through the connection channel below the calcination zone.
3.2 The fuel is supplied through the spray guns which are installed in the kiln chambers, moving and burning in parallel flow with the limestones.
3.3 One kiln chamber is burning, and the other is regenerative. The two kiln chambers alternate continuously to realize limestones' high efficient calcination.
3.4 The flue gas with high temperature is led to the regenerative kiln chamber. In addition, the cooling air of the lime is blown from the bottom of the cooling zone. Then it realizes the mixing flow with the heating flue gas in the regenerative kiln chamber.
3.5 All of the flue gasrealizes countercurrent flow with the limestones to preheat the materials effectively, then ejected through the dust removal system to the atmosphere. The temperature of the flue gas drops to 120 ºC or so.
3.6 The limestones are put into the two kiln chambers alternately at regular intervals, and distributed in the same time. Also there are material level indicators equipped.
3.7 It's positive pressure in the kiln chamber, 20~25KPa or so.
3.8 The temperature of the flue gas drops to 120 ºC or so.

4. Energy consumption: 850~900kcal/kg·CaO

5. Power consumption:
limestone with grain size 30~60: ~40kW·h/t·CaO;
limestone with grain size 20~40: ~48kW·h/t·CaO;

6.Available grain size of limestone
6.1 Available grain size range: 30~90.
6.2 Max. dia.to Min. dia.ratio is 2.0 or so.

7. Lime Activity: ≥360ml (4N HCL 10min)

8. Features
8.1 The lime kiln with double chamber has simple structure, and it's easy to construct & maintenance.
8.2 The lime kiln with double chambers has advanced technology. It's easy to control, to operate, to inspect.
8.3 The finished product has high activity to meet different requirements. It will be widely used in various industries.
8.4 Low energy consuption
·The calcination in the kiln chambers is realized with parallel flow during the limestones. So the limestones are heated with good condition.
·The flue gas preheats the limestones in the regenerative kiln chamber directly. The heat is recovered with the highest efficiency, without the heat exchanger additionally.
·It could realize steady and uniform calcination through the control of fuel amount in the spray guns.
8.5 Easy operation with lowest operation cost
·Single flow, less management point;
·Advanced automatic control system;
·One operator is available.
8.6 The lime kiln with double chambers has simple structure for easy construcution and maintanence. The service life of the refractory lining is about 5~7 years once normally.
