The twin shaft lime kiln is a new type of kiln, also called double shaft parallel flow regenerative lime kiln, which is a kind of vertical kiln. It adopts double-chamber structure design and flow heat storage, saving energy and reducing the calcination cost of the kiln. It is a very advanced kiln type.

1. The cross section of the lime kiln is composed of two semi-circular kiln bodies, which are connected by the connecting channel under the calcination zone.

2. The fuel is supplied by the spray gun installed in the kiln chamber, which flows and burns in parallel with the limestone.

3. One kiln chamber for combustion and one for heat storage. The two kilns are continuously alternated to realize efficient calcination of limestone.

4. High temperature flue gas is led to regenerative kiln chamber. In addition, the cooling air of lime is blown in from the bottom of the cooling zone. Then realize mixed flow with heating flue gas in the regenerative kiln.

5. The flue gas and limestone are all countercurrent to effectively preheat the materials, and then discharged into the atmosphere through the dust removal system. The flue gas temperature drops to about 120 ℃.

6. Limestone shall be put into two kilns alternately at a certain interval and mixed at the same time. It is also equipped with a level indicator.

7. Positive pressure of kiln chamber, about 20~25KPa.

8. The flue gas temperature drops to about 120 ℃.

9. Energy consumption: 850~900kcal/kg CaO

10. Power waste:

Grade 30~60 limestone: ~40kW · h/t · CaO;

20-40 limestone: ~48kW · h/t · CaO;

11. Available size of limestone

Available particle size range: 30~90.

The maximum and minimum diameter dia.ratio is about 2.0.

Lime activity: ≥ 360ml (4N HCL 10min)

1. The double-chamber lime kiln has simple structure and convenient construction and maintenance.

2. The double-chamber lime kiln has advanced technology. It is easy to control, operate and check.

3. The finished product has high activity and can meet different requirements. It will be widely used in all walks of life.

4. Low energy consumption · kiln chamber calcination realizes parallel flow in limestone process. So limestone is heated under good conditions· The flue gas directly preheats the limestone in the regenerative kiln. The heat is recovered with the highest efficiency without additional heat exchanger· Stable and uniform calcination can be achieved by controlling the amount of fuel in the spray gun.

5. Simple operation, lowest operation cost, single process and few management points· Advanced automatic control system· One operator shall be equipped.

6. The double-chamber lime kiln has simple structure and is easy to construct and maintain. The service life of refractory furnace lining is generally about 5~7 years.
