What are the factors to be considered in the design of incinerators?

Aspects of prime importance in design to be considered are: the incineration mechanisms and their selection, the grate firing systems, furnace geometries, secondary air injection, the 3Ts, the heating value or calorific value of the waste, theoretical Air to Fuel ratio and the excess air requirement.

What is the main problem with incineration?

This process of waste incineration poses a significant threat to public health and the environment. The major impact on health is the higher incidence of cancer and respiratory symptoms; other potential effects are congenital abnormalities, hormonal defects, and increase in sex ratio.

What temperature does an incinerator burn at?

Temperature: Most incinerators operate at higher temperatures than the ignition temperature, which is a minimum temperature. Thermal destruction of most organic compounds occurs between 590/C and 650/C (1100/F and 1200/F).

What is modular incinerator?

Modular incinerator units are usually prefabricated units with small to medium capacities of between 5 and 120 tons of solid waste per day. Typical facilities have between one and four units for a total plant capacity of about 15 to 400 tons per day.

What is pyrolytic incinerator?

The pyrolytic incinerator comprises a pyrolytic chamber and a post-combustion chamber. Medical waste is thermally decomposed in the pyrolytic chamber through an oxygen-deficient, medium-temperature combustion process (800– 900°C), producing solid ashes and gases.

What type of waste is incinerated?

TYPES OF WASTE INCINERATED Three types of waste to which incineration is applied extensively are municipal solid waste, hazardous waste, and medical waste. Incineration of those three types is the focus of this discussion.

What are the pollutants from incineration?

Pollutants emitted by incinerators that appear to have the potential to cause the largest health effects are particulate matter, lead, mercury, and dioxins and furans.

What is final product in incineration?

Complete answer: Ashes is the final product in incineration. Incineration produces ash and bottom ash just as is the case when coal is combusted.
