The regulating role of secondary air in the hydrogen production converter
Thread Content
Besides serving as supplemental air, what role does the secondary air in the hydrogen production converter play in regulating the flame shape? What are the effects of increasing or decreasing its flow rate, and under what circumstances should the secondary air be adjusted?
The secondary air serves primarily to assist in combustion, while also acting as a cooling mechanism to prevent the steel plates from overheating. If all the primary air were introduced into the furnace through the primary air inlet, the wind speed would be too high, affecting the stability of the flame; in some cases, it might even extinguish the flame, preventing it from being reignited. The use of secondary air is also intended to ensure stable combustion and complete burning – by adjusting the amount of secondary air, it is possible to control the oxygen content in the flue gases.
