What temperature range does fluidized bed combustion occur?

Fluidized bed combustion is a technology designed to burn solid fuels in an efficient and controlled manner. The temperature range in which fluidized bed combustion typically occurs is between 800℃ and 900℃. This range is optimal for several reasons:

1. Combustion Efficiency: At these temperatures, the combustion of the fuel is efficient, allowing complete combustion of many solid fuels. Higher temperatures provide sufficient energy to ensure that the volatile components in the fuel are released and combusted effectively.

2. Emissions Control: Operating within this temperature range helps in reducing emissions of nitrogen oxides (NOx), which tend to increase at higher temperatures. The combustion process is better regulated, allowing for the minimization of pollutant formation.

3. Slagging Prevention: The temperatures in this range are low enough to avoid significant slagging—a process where molten ash fuses and accumulates—while still being high enough to promote efficient combustion.

Thus, the 800℃ to 900℃ range strikes a balance between efficiency, emission control, and operational reliability, making it the ideal temperature zone for fluidized bed combustion systems.
