What is a flameless waste incinerator?

 

A flameless waste incinerator, also known as a flameless thermal oxidizer (FTO), uses flameless combustion technology to destroy organic compounds in the waste stream within a container at low temperatures of 50-380°C (rather than traditional flames). This process creates a stable, progressively increasing thermal reaction zone from bottom to top, with even heat distribution. It requires no auxiliary (natural) environment, resulting in lower noise levels, higher efficiency, and reduced dioxin and particulate matter emissions. The PRC Fireprint equipment uses a small amount of hot magnetic oxygen and ambient air to preheat the waste and convert it into charcoal. The charcoal then pyrolyzes to form combustible gases and powdered ceramic ash, a process with minimal hazard.

 

How Flameless Combustion Works

 

Preheating: A small amount of charcoal is used as a heat source to preheat the furnace, raising the temperature gradient from 380°C to 50°C.

 

Thermolysis Principle:

 

The charcoal decomposes at 380°C without flames. The rising airflow generates combustible gases, which solidify into powdered ceramic ash. Emissions: Combustible gas is directed to a generator, burned to produce electricity, and discharged through a chimney.

 

Fireprint Key Advantages

 

Reduced Emissions: Flameless combustion significantly reduces harmful emissions, such as dioxins and heavy metals.

 

High Destruction Efficiency: It achieves very high Destruction Removal Efficiency (DRE), typically up to 99.9999% for organic compounds.

 

Energy Efficiency: A stable process and higher thermal efficiency reduce fuel consumption.

 

Stability: Uniform temperature distribution and the absence of visible flames make the combustion process more stable and quiet.
