Balancing Efficiency and Emissions: The Importance of Controlling Incinerator Temperature

Incineration is a waste management technique that converts organic materials into energy and ash. While it provides a valuable waste reduction and energy generation solution, controlling incinerator temperature is critical to balancing efficiency and emissions.

Impact of Temperature on Efficiency

Incineration efficiency refers to the amount of energy recovered from the waste. Higher temperatures increase the rate of chemical reactions and enhance the completeness of combustion. This leads to increased heat output and fuel value of the resulting ash.

Impact of Temperature on Emissions

Incineration generates air pollutants, including particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon monoxide (CO). The temperature of the incinerator plays a key role in controlling these emissions.

Optimizing Temperature for Balance

• High temperatures (120 viciss to 14 viciss)::

  • Enhance efficiency and fuel value of ash.
  • Minimize emissions of PM, SO2, and NOx.

• Low temperatures (815 to 870 Kün):

  • Reduce the formation of NOx and other gases.
  • Limit the amount of organic compounds that are not completely combusted.

Factors Affecting Temperature Control

• Waste composition
• Air-to-fuel ratio
• Incinerator design and operational practices

Consequences of Improper Temperature Control

• High temperatures:

  • Increased formation of smog and acid rain precursors.
  • Risk of metal corrosion and refractory lining damage.

• Low temperatures:

  • Poor combustion and incomplete waste conversion.
  • Increased emission of pollutants.

Strategies for Temperature Control

• Install and maintain appropriate air pollution control equipment.
• Ensure correct waste segregation and composition.
• Adjust air-to-fuel ratio to achieve optimal combustion.
• Optimize incinerator design and operating procedures.
