The refractory of burner secondary

A non-oxidizing furnace air ratio due to the reduction, a reducing atmosphere is formed, so the exhaust gas contains a large amount of carbon black. To remove the carbon, the need for a secondary combustion, but the secondary combustion burner attached to the kiln in the internal lining of refractory material with a special shape, for mixing with the combustion air with high efficiency, using a secondary combustion burner to a stable state However, after the high temperature stability of the region, due to the exhaust gas can be spontaneous, so almost no auxiliary burner.

Further, when the asphalt impregnated refractory firing,

the exhaust gas contains benzo flowers, over 800 ℃ glass printer after the secondary combustion gas exhaust prior to discharge to protect the machine, using the dilution air cooling. With this operation due to large heat loss, so that the future need for cooling in the heat exchanger before dilution to improve combustion efficiency.

Although the total amount of fuel in the kiln is reduced, but because production resulting brick firing tunnel kiln operating rate is reduced, so that fuel consumption may not be reduced. On the other hand, due to the low sulfur fuels, as well as gas treatment, significantly reducing the pollution of the environment. Meanwhile, the operating environment has also been improved, although there is dust in

the work site, but has reached a level not need to wear a dust mask. In the refractory market, large quantities of products will remain subject to lower prices of imported products, the pressure that has further enhanced the trend of small quantities of many varieties.
