What is a Vapor Combustor Unit, and how does it work?
Similar to a Thermal Oxidizer, a Vapor Combustor Unit (VCU), operates at high temperatures where the temperature is raised to the point that VOC chemical bonds are broken.
The purpose of the burner on the combustor is to input the heat energy required to raise the inlet temperature to the required chamber operating temperature.
Heat from combustion requires induced natural draft air or a dilution air fan for proper combustion and cooling. The cooling air is required during periods in which the vent gas has sufficient heating value to raise the VCU operating temperature above the high set point. The system dilution air fan or louvers are differently for each application.
The VCU chamber is typically lined with high temperature ceramic fiber insulation to protect the outer steel shell. Soft refractory lining is installed to allow for rapid heat up without thermal shock issues that would accompany hard refractory designs. Soft refractory undergoes minimal expansion and contraction and is ideal for applications such as this that require high levels of on/off or cyclic operation or on systems that require transportability.
Different than a Thermal Oxidizer, a VCU processes a vent stream that is not flammable until it reaches the inside of the VCU combustion chamber. The waste gas either contains very little oxygen or is inerted out of any flammable ranges before entering the destruction chamber. A Thermal Oxidizer process waste gases where the make-up is below 50% of the Lower Flammability Limit (LFL).
