What is a ceramic burner? | red ceramic burners | high quality

The burner is an important equipment of the hot blast stove. It burns coal gas with the help of combustion air. The quality of its combustion affects the maximum temperature of the flue gas and the utilization of the gas. The grid-type or sleeve-type metal burners used in the 1950s and 1960s have the disadvantage of poor mixing of gas and combustion air, poor combustion, and pulsation. Since the late 1960s, they have been gradually replaced by ceramics. Replaced by burners. The so-called ceramic burner is the burner made of ceramic refractory materials. The ceramic burners used in small and medium blast furnaces are mostly made of high alumina phosphate heat-resistant concrete or bauxite heat-resistant concrete, while modern large and medium blast furnaces use high alumina Ceramic burners made of bluestone refractories are also made of mullite cordierite refractories. Ceramic burners are now divided into three types: flameless, flameless and half flame (Figure 1-7-22). Sleeve type and rectangular ceramic burners are flame, grid type is short flame and flameless, and the three-hole type used for high calorific value gas enrichment is half flame. Most domestic hot blast stoves adopt the sleeve type because of its simple structure, easy production and low resistance loss, and it is suitable for improving internal combustion type hot blast stoves.
