Industrial Incinerators: How Waste Incineration Systems Work

What Is an Industrial Incinerator and How Does Incineration Work?

An incinerator is a specialized device used for burning waste materials, efficiently reducing it to ash. The concept of waste incineration has existed for thousands of years as communities searched for solutions to manage waste. With the advent of the industrial revolution, the challenges associated with waste disposal grew more complex. New industries began generating hazardous materials, creating a critical need for efficient, safe, and environmentally responsible incineration technologies.

Common Types of Waste Incinerated:

  • Agricultural waste
  • Municipal and commercial refuse
  • Medical and hospital waste
  • Industrial byproducts
  • Biological materials and human remains

At its core, incineration is the controlled burning of solid or liquid materials at high temperatures often between 1400°F and 2200°F depending on the application. This is achieved with a long, luminous, but controlled flame reaching directly on the waste. This allows for more effective incineration of the waste. The flame will either be used for light off only or continuously on to ensure complete decomposition. The goal is to convert waste into ash which can then be more easily disposed.

Table 1 – Common Waste Categories (By Weight and Heating Value)
Waste Class Waste Type Calorific Value Input Needed Examples
No.1 Dry/Combustible Waste High Flame only needed for light off Plastics, Rubber, Dry Paper/Cardboard
No. 2 Average Municipal/ Commercial Waste Medium  70lbs per 100MBH Municipal Solid Waste (MSW), Mixed Commercial Waste
No. 3 Low Calorific/Wet Waste Low 25lbs per 100MBH Sewage Sludge, Food Waste, Contaminated Solids
No. 4 Essentially Non-Combustible Very Low  13lbs per 100MBH Aqueous Slurries, Highly Mineral Waste

For safe and compliant operation, refer to Title 40 Protection of the Environment – Code of Federal Regulations (CFR), ANSI Z223.1, National Fuel Code, and any other relevant local codes. Additional classifications of waste can be found on the US EPA’s website here. 

Key Components of Modern Industrial Incinerators

A modern incineration system typically includes several key components that work together to ensure efficient and safe disposal of waste materials. At the heart of the system is the combustion chamber – a robust enclosure where waste is exposed to high temperatures and the controlled flame essential for thorough decomposition. This chamber is designed to withstand intense heat and maintain optimal combustion conditions.

  • Combustion chamber: The main area where waste is incinerated under controlled high temperatures, transforming organic matter into ash and significantly reducing volume.
  • Burner: Midco’s Incinomite burner supplies the necessary flame to ignite and sustain the combustion process. These burners can fire downward at a 10° angle which can help direct heat and improve burn efficiency for different waste types.
  • Airflow and draft controls: These regulate the amount of oxygen in the combustion chamber which is crucial for complete waste breakdown and efficient burning. When a natural draft is used and the chimney exceeds 25 feet in height, a barometric damper is recommended to stabilize airflow and maintain proper draft.
  • Emissions management components: Modern incinerators are equipped with filters, scrubbers, or other devices that capture and treat exhaust gases and particulates, helping to minimize environmental impact and meet regulatory standards.

All of these components are combined to ensure that incineration not only reduces the volume of waste but also does so in a manner that is efficient, safe, and environmentally responsible.
