Pressure issues in the afterburner
Thread Content
The temperature of the gas after sintering is too low; therefore, a make-up burner is added so that the gas from this burner mixes with the sintering gas in the preheating vessel to generate steam. The problem is that the boundary zone specifies an outlet pressure of -1.0 KPa for the furnace, and this vacuum level is much higher than the positive pressure required for normal furnace operation. The proposed solution involves installing a pressure-reducing orifice plate at the outlet of the afterburner. I would like to know if this approach is used in practice; if not, are there any other alternatives?
Negative pressure isn’t a problem; as long as you control the combustion in the afterburner properly
