A waste incinerator (also known as a waste combustion furnace) is an eco-friendly mechanical device designed to treat waste through high-temperature pyrolysis and oxidative decomposition. It utilizes auxiliary fuels (such as oil or natural gas) to forcibly ignite the waste and maintain high temperatures within the combustion chamber, thereby achieving the harmless disposal, volume reduction (reducing volume by 80%–85%), and resource recovery (e.g., waste-to-energy generation) of the waste.
Based on processing capacity and application scenarios, waste incinerators are primarily categorized into the following three types: Portable/Small-to-Medium-Scale Incinerators: Suitable for use in field camps, mining sites, or remote communities. Medical and Animal Waste Disposal Equipment:Specifically designed for hospitals, veterinary clinics, and livestock farms, and equipped with rigorous exhaust gas and smoke treatment systems. Large-Scale Waste-to-Energy Plants: The core infrastructure for urban municipal solid waste management, utilizing waste heat boilers to convert the high-temperature steam generated during combustion into electrical energy. The core operating principles and processes typically encompass the following key systems:
Combustion System: Includes pre-treatment (screening, drying), a feeder mechanism, and a combustion chamber equipped with auxiliary burners, ensuring that the waste undergoes complete pyrolysis and carbonization at temperatures ranging from \(850\text{℃}\) to \(1100\text{℃}\).
Flue Gas Purification System: A secondary combustion chamber ensures the complete decomposition of harmful gases (such as dioxins); the gases are then purified—using equipment such as spray towers and baghouse filters—to meet regulatory emission standards before being discharged.
Energy Recovery System: In large-scale facilities, the thermal energy generated during combustion can be utilized for electricity generation or district heating (cogeneration).
