Self-Sustained Oxidation Flow (SSOF)
Heat established. Fuel removed. Flow sustains.
Self-Sustained Oxidation Flow (SSOF) is the term used by AZADrg to describe a thermal oxidation behavior in which combustible gases generated from synthetic polymer compound waste (SPCW) continue to oxidize through the interaction of established heat and controlled air supply.
SSOF is not a separate machine or combustion chamber. It describes the behavior that develops inside a thermal architecture when gas formation, air introduction, flame, and heat become part of a continuing oxidation flow.
How the Flow Begins
The process begins with heating. During initial heating, thermal decomposition of SPCW produces combustible gases. These gases encounter oxygen and begin to oxidize, forming an active gas-phase flame region.
At this stage, auxiliary fuel may be used to establish the thermal condition. Its purpose is to initiate and stabilize the process rather than to remain the continuous energy source for operation.
Staged Oxidation Behavior
As heat and gas generation increase, combustible gases move upward through successive air-interaction zones. Air introduced at different levels interacts with gases that have not yet completed oxidation in the preceding region.
- Stage 1: thermal decomposition, gas generation, and initial oxidation.
- Stage 2: continued gas-phase oxidation as remaining combustible gases encounter additional air within a higher-temperature region.
- Stage 3: a further oxidation region for combustible gases that continue beyond the lower stages.
These stages are not intended to function as isolated combustion chambers. Together they form a continuous oxidation path within a single thermal field.
The Self-Sustained Condition
A significant transition occurs when sufficient heat has accumulated and oxidation of the gases generated from the waste produces enough thermal energy to support continued gas formation.
At this point, the auxiliary fuel used during initial heating can be removed. SPCW becomes the source of combustible gases, while controlled air supply continues to support their oxidation.
Heat established. Fuel removed. Flow sustains.
This transition is the defining operating condition of SSOF.
Flow, Not a Single Flame
SSOF should not be understood as one fixed flame at one fixed location. The visible flame is part of a larger and continuously changing interaction among heat, combustible gases, oxygen, and movement within the chamber.
Different waste conditions can change the intensity and position of the visible flame. The essential feature is therefore not the appearance of a particular flame shape, but the continuation of gas-phase oxidation through the staged thermal field.
What SSOF Is — and Is Not
SSOF is a description of oxidation behavior. It does not refer to a burner, a secondary combustion chamber, an afterburner, or a particular proprietary machine.
Nor does the term itself constitute an emissions claim. Actual thermal performance and emissions must be evaluated from operating conditions and measurement data.
The purpose of the term is simply to identify the condition in which oxidation continues after auxiliary fuel is removed and the thermal process is sustained by the interaction of the waste-derived gases, established heat, and controlled air supply.
From Behavior to Architecture
SSOF describes the behavior. The Augean Flow Core (AFC) is the physical architecture developed to establish and maintain the conditions in which that behavior can form.
In simple terms:
- Gas-Phase Oxidation explains the principle.
- SSOF describes the behavior.
- AFC provides the architecture.
No burner. No secondary chamber. No lid.
Heat established. Fuel removed. Flow sustains.
