With the development of economy and the digitalization of the science and technology, the infrastructure and skyscraps are  symbols of urbanisation in a lot of developed and developing countries accompanying demands of cement industry are booming with.

Increasing the capacity or productivity is a trend to choose for many cement manufacturer. to reduce the cost and add value,to save energy and reduce the emission ,is a way to sustainable development approach.

Kiln and cyclone and pre heater system upgrading and modernization are most ordinary methods to increase the capacity in the cement producing process.

The exemplary project as below:

Kiln retrofit and modernization.

Background of kiln

1,The production of kiln of this line is 2500tons per day established in 2010

2,The production is not reliable between 2900 and 3000 tons because of the shortage of design,and the stringency of clinker is only 55MPA

3,Large consumption of coal at rate of 114-116kg/ton which costly a lot

4,Ammonia water consumption is high at rate of 3kg,(emission 260mg/m3)

Retrofit and modernization items:

1,Target in contract.

Production above 3100 t/d

Consumption of coal below 110kg/t-cl

ammonia water consumption less than 3kg when emission 200mg/m3

2，Methods

Lengthen the pipe of decomposing furnace,optimize the air system to reduce the obstruction pressure.

Air input optimized,change the position of third airflow input,replace the burner of decomposing furnace to reduce the emission of NOX.

Replace the new smoking house
