Alumina Heat Storage Ball

The main raw material of high alumina heat storage ball filler is ultrafine alumina powder. After advanced production molding technology and high-temperature tunnel kiln firing, the high-alumina heat storage ball filler has good acid resistance and heat resistance. It also makes the high-alumina heat storage ball filler ball have the characteristics of high purity, high strength, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, good thermal stability, and stable chemical properties. It has a favorable position and market demand in major industries.

Working principle and features

1. High aluminum heat storage ball is a large number of balls will be divided into small flow strands, the flow in the heat conduction body, the formation of strong turbulence, through the surface of the surface of the heat conduction layer, ball diameter is very small, small conduction radius, small thermal resistance, high density, good thermal conductivity, so it can achieve the requirements of frequent and rapid reversal of heat conduction burner.

2 thermal conductivity can be used 20~30 times /h of the commutation, high temperature flue gas through the thermal conductivity bed after the flue gas can be reduced to 130℃ or so.

3. High temperature gas and air flow through the heat conductor in the same path can be respectively preheated to only about 100℃ lower than the flue gas temperature, temperature efficiency up to more than 90%.

4. Because the volume of the heat conductor is very small, the flow capacity of the high aluminum heat storage ball bed is strong, even if the resistance increases after ash accumulation does not affect the heat exchange index.

5. High aluminum heat storage ball has the characteristics of oxidation resistance and slag resistance.

6. The replacement and cleaning of high aluminum heat storage ball is very convenient.

Size

Main specifications of high aluminum heat storage ball: 3mm, 6mm, 8mm, 10mm, 13mm, 16mm, 19mm, 25mm

Application

Height storage ball is widely used in industrial furnaces such as steel, metallurgical industry heating furnaces, forging furnaces and so on. It is used for the regenerator of air separation equipment and the blast furnace gas heating furnace of iron and steel plant as regenerative filler, double preheating of gas and air, so that the combustion temperature can quickly meet the requirements of rolling steel for heating billets.

The main function of the high alumina storage ball is to support and cover the catalyst in the reactor. It buffers the effects of liquids and gases on the catalyst, thereby improving the distribution of liquids and gases in the reactor. Then follow the steps below to understand the function and commonly used specifications and models of high-aluminum heat storage balls.
