Virtually every industrial manufacturing process results in waste products— cause for concern in today’s environment. Thermal oxidation has proven through the years to be an effective and safe method for the disposal of a wide variety of industrial wastes if proper thermal oxidizer design practices are followed.
Thermal oxidizer design can be relatively straight forward or complex depending on the application, waste characteristics, and the air permit emission requirements. Most thermal oxidizer designs incorporate similar design principles to ensure that the desired oxidation reaction occurs and the waste stream contaminants are reduced to the levels necessary to achieve emission compliance.
How do you go about developing a thermal oxidizer design?
An important first step in any successful thermal oxidizer design process is providing the thermal oxidizer supplier with clear and specific process design “inputs” and “outputs.”
Here are typical thermal oxidizer design inputs and outputs.
Typical Design Inputs:
Typical Design Outputs:
Begin thermal oxidizer design process.
Once these parameters are defined, the thermal oxidizer design process can begin. A basic thermal oxidizer system consists of a refractory lined vessel known as the thermal oxidizer, a burner, stack, and combustion controls.
“The Three T’s” of Combustion.
These are required in order to achieve successful thermal oxidation:
The Three T’s of Combustion, along with sufficient oxygen, are essential and interrelated in all thermal oxidizer designs. The level of turbulence (mixing), the necessary reaction temperature, and the amount of time (residence time) is primarily dependent on the waste stream characteristics and the level of destruction required for achieving the specific air permit compliance.
PCC custom designs all of our thermal oxidizer systems. Our extensive industrial application experience coupled with our experience in handling a wide spectrum of waste streams, give us the expertise to determine how best to incorporate the Three T’s of Combustion into each thermal oxidizer design.
Determine essential design features.
As we mentioned, a basic thermal oxidizer system includes a refractory system, burner, exhaust stack, and combustion controls. More complex thermal oxidizer systems include heat recovery such as gas to gas heat exchangers and waste heat boilers, plus additional downstream pollution control equipment such as scrubbers, particulate filters, and wet ESP’s. Each of these components have a variety of important design features (too extensive to discuss here), which must be considered to ensure the complete thermal oxidizer “system” is safe, reliable, and meets all performance objectives.
