Design Temperatures for Small Oil-Fired Waste Incinerators

Design Temperatures for Small Oil-Fired Waste Incinerators

Solid waste incineration temperatures typically range from 850°C to 1200°C. The specific temperature and required residence time depend on the waste composition and regulations, but a minimum temperature of 850°C and a residence time of at least two seconds are generally recommended.

Hazardous waste, particularly waste with a high content of halogenated organic matter, may require higher temperatures, 1100°C or higher.

General Incineration Temperatures

Typical Range: 850°C to 1200°C

Minimum Requirement: For complete combustion, the gas must be maintained at at least 850°C for at least two seconds.

Hazardous Waste: If the waste contains more than 1% halogenated organic matter (such as chlorine), the incineration temperature can be increased to 1100°C for at least two seconds.

Incineration Factors: Waste Composition:

The type and amount of contaminants in the waste influence the required temperature.

Residence Time: The length of time the waste is exposed to the heat is crucial. For example, solid waste may require 30 to 90 minutes, while liquid and gaseous waste may only require a few seconds. Oxygen Supply: The amount of air or oxygen added to the chamber affects the combustion process and temperature.

Technology: Different incineration technologies, such as grate, fluidized bed, or rotary, operate within different optimal temperature ranges.
