fire-resistant high alumina ball used in hot blast stove and heat transformer
Fire-resistant high alumina ball is made of industrial alumina and refractory clay by scientific formulation and high temperature calcination. It has:
1. Good chemical stability, no chemical reaction with materials.
2. High mechanical strength and long service cycle.
3, high temperature resistance, heat temperature can reach 1700 degrees Celsius.
Especially suitable for high and low temperature converter furnace, converter furnace, push plate kiln ball to disperse gas and liquid, and support, cover and protect catalyst
Function, also can be used in the iron and steel industry hot blast furnace and heating conversion equipment
The main problem encountered in the use of refractory ball is that the high aluminum refractory ball due to its high hardness, brittleness is also large, dry grinding easy to cause nodular stone cracking, the surface of the pebble potholes, resulting in very high abrasion phenomenon, can only be used to polish the pebble before leaving the factory, pick out the cracked or high abrasion pebble
The high efficiency heat storage bulb produced by our factory has a specific surface area of 240m2/m3.
Many small balls divide the airflow into small flows. When the airflow passes in the heat storage body, strong turbulence is formed, which effectively breaks through the boundary layer on the surface of the heat storage body. Moreover, due to the small ball diameter, small conduction radius, small thermal resistance, high density and good thermal conductivity, frequent and fast directional reversal of the heat storage burner can be realized.
The regenerator can change direction 20~30 times /h, and the flue gas can be reduced to about 130℃ after passing through the bed of the regenerator. The high temperature gas and air flowing through the regenerator can be preheated to about 100℃ lower than the flue gas temperature in the same path, and the temperature efficiency is over 90%.
Because the volume of the regenerator is very small and the circulation capacity of the pellet bed is strong, the heat transfer index will not be affected even if the resistance increases after ash accumulation. The regenerative bulb has the characteristics of strong oxidation resistance and slag resistance.
It is very convenient to replace and clean the regenerative ball and can be reused
