Product Description

Heat storage ceramic ball

1. Mass small balls divide airflow into small flow.When airflow pass through in heating storage ball,disordered flow is formed.It bursts boundary layer of storage ball.Because of small diameter of ball,small conductive diameter,small heating block,high density,good conductivity.The requirement that heating storage type burner commute frequently and speedily can come true.
2. Heat accumulator make use of 20~30 times/h commutation,after the high temperature smoke flow trough bed layer of heat accumulator,the smoke flow falling to 130 C is discharged.
3. In the same pathway,the high temperature coal gas and airflow through heat accumulator can warm up respectively to lower by about 100 C than temperature of smoke gas.The efficiency of temperature can reach more than 90%.
4. The volume of heat accumulator is very smart and the circulating ability of ball bed is strong,so it will not influence heating exchange index even if resistance increase after ash deposition.
5. The heating storge ball have strong oxidation resistance and slag-resistane ect.

Characteristics:

Heat-storage ceramic ball is featured with high strength, wear resistance, large thermal conductivity ,heat capacity, good heat storage and heat stability etc. It can pre-heat both coal gas and air to rapidly increase the combustion temperature to meet the billet heating requirement in steel rolling equipment. Furthermore, it is not easy to crack when the temperature changes sharply.

Advantage:

Refractory ball usually used in shift converter and reformer in ammonia plant.

Refractory ball has a lot of advantages, such as:

High strength, long use period
Chemical stability, it won't react with our materials

Good performance of resistance high temperature,  resistance high temperatue up to 1900

 Application:

It is especially applicable as heat storage packing of heat accumulators of air separation plants and gas heating stoves of blast furnace in steel plants.
