Flame Nozzle Castable for Biomass Burner

In a biomass burner, the flame nozzle is an important component for putting biomass pellet fuel into the combustion chamber, so the refractory castable used at the flame nozzle is crucial to the normal operation of the biomass burner.

Selection factors for fire-throwing nozzle castables:

1. High-temperature resistance: The flame nozzle will be impacted by high temperatures during the biomass combustion process, so the castable needs to have good high-temperature resistance and be able to withstand thermal stress and corrosion in high-temperature environments.

2. Thermal conductivity: The thermal conductivity of the castable will affect the heat dissipation effect of the flame nozzle. Choosing castables with good thermal conductivity can improve the thermal conductivity of the flame nozzle and reduce heat loss.

3. Anti-corrosion performance: Ash and chemicals produced during biomass combustion will cause corrosion to the flame nozzle. Therefore, the castable needs to have good corrosion resistance to extend the service life of the flame nozzle.

Based on the analysis of the selection of castables for biomass burner flame nozzles, we formulated refractory castables that meet the requirements for use. That is, the flame nozzle is castable.

The flame nozzle castable has the characteristics of high refractory temperature, good compressive strength, good thermal shock stability, flame erosion resistance, and good wear resistance. It is suitable for parts with higher strength requirements, wear resistance, and erosion resistance.

In practical applications, the biomass burner constructed with flame nozzle castables can work stably for a long time and has good use effects.
