An incinerator is a container used for burning biological refuse. It can also be an industrial plant designed for large-scale refuse combustion.

Incinerators are used to safely dispose of solid, liquid, and gaseous wastes that result from manufacturing processes. They recuperate energy and can be used to generate electricity by steam or thermal flow through the use of auxiliary equipment like steam boilers. Modern incinerators include air pollution control equipment to reduce negative impacts on the environment.
