Natural gas bauxite shaft kiln: desulfurization and denitrification equipment

1、 Introduction to bauxite clinker: bauxite clinker is a solid block material made from bauxite raw stone calcined at high temperature in rotary kiln, shaft kiln, inverted flame kiln and other kilns. The main purpose of calcination is to remove water of crystallization and increase alumina content. The clinker is grayish white, light yellow and dark gray bauxite clinker due to the difference of iron or other potassium and sodium elements. Alumina clinker, also known as high alumina clinker, is a widely used refractory or anti-corrosion material in the metallurgical industry and other industries to produce various high alumina bricks. It is especially used on the top of electric furnaces, blast furnaces, and hot blast furnaces, with significant refractory effects and superior performance to ordinary clay refractory bricks.

Due to environmental reasons, the bauxite shaft kiln needs to be converted to clean energy such as natural gas, blast furnace gas, coke oven gas, converter gas, light hydrocarbon gas, and biogas as fuels. In response to this situation, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. has innovated the bauxite shaft kiln burner, which can be classified into natural gas bauxite shaft kiln burner, blast furnace gas bauxite shaft kiln burner, coke oven gas bauxite shaft kiln burner, and Converter gas alumina shaft kiln burner, light hydrocarbon gas alumina shaft kiln burner, biogas alumina shaft kiln burner, etc.

2、 Classification and characteristics of alumina shaft kiln burners:

1. The burner adopts a stable flame disc structure design, and the air mixture follows the principle of fuel combustion, with accurate proportion, sufficient combustion, and significant solar term effect. Based on the production status of bauxite shaft kilns, the flame length of the burner should be cooked to avoid the occurrence of raw materials in the middle of the kiln. Due to the characteristics of natural gas fuel, the flame is rigid and short. If natural gas is used as fuel, there are requirements for the diameter of the vertical kiln. Please communicate and exchange details with the Zhongwei Technology Department.

2. The layout of the burner of the bauxite shaft kiln should be reasonable. The natural gas burner is generally arranged in a high-temperature calcination zone, with an upper and lower layout. After uniform calcination at high temperature, the material is cooled and sent to the silo.
