FRALCO Alumina Ball Cleaning Machine
Generally, the heat exchange ball is used for about 3 months, and the top part of heat exchange ball of the heat exchange box will be partially damaged because of the influence of long-term rapid cooling and heating. And because the furnace gas itself is not clean, it will cause dust pollution to the heat storage ball inside the heat storage box. Heat storage ball needs to be cleaned, replaced and replenished regularly. In order to improve the life of the regenerative ball and reduce the labor intensity of the workers, the company has developed a regenerative ball washing machine, which can effectively improve the service life of the regenerative ball and reduce the cost.
ALMELT Heat Storage Ball Characteristics
the alfa alumina (corundum) spheres were made by sintering the spheroidized calcined alumina at a melting point temperature of 3704℉(2040℃. The main process is divided into rolling and pressing.
In the working process, many heat storage balls in the heat storage tank divide the air flow into very small flow strands, and the air flow forms strong thunderstorm when it flows in the heat conduction body, which can effectively absorb the heat on the surface of the heat conduction body, so the regenerative burner can be changed frequently and quickly. After the high temperature gas flows through the regenerator, the temperature can rise to only about 100℃ lower than the flue gas temperature, and the temperature efficiency is more than 90%.
The corundum heat storage ball is made of industrial alumina as the main raw material. It has the characteristics of low shrinkage, high temperature load softening temperature, corrosion resistance, high strength, large heat storage and discharge, good thermal shock stability, good thermal conductivity and small number of thermal expansion.depending on customer requirements, the diameter of the ball varies from 1/8 inch to 2 inch (tolerance ±6% mm).
