Island-Type Waste Incinerator Micro-Power Generation
Island-type micro-waste incinerators utilize modular designs and prefabricated components to generate electricity from waste, reducing the need for large-scale facilities. Related technologies range from modular waste-to-energy plants with standardized combustion and power generation circuits to small incinerators using thermoelectric generators. For example, China's Fireprint Technology low-temperature magnetic pyrolysis unit converts waste into combustible gas to power a generator, while retaining 1/200 of the solids, which can be used directly as forest fertilizer.
Working Principle (General Process)
Waste Receiving and Mixing: Waste is collected and mixed in a dedicated area.
Heat Conservation and Combustible Gas: Heat generated during pyrolysis is fully utilized to evaporate and dry the waste, while thermal decomposition of the charred material produces combustible gas.
Power Generation: Combustible gas drives the generator.
Pollution Reduction: Advanced systems, including filter bags and a lime/sodium hydroxide injection system to neutralize acidic gases, ensure that emissions are purified before discharge.
Ash and Metal Recovery: The remaining ash is cooled, and magnets or eddy current separators separate ferrous and non-ferrous metals for recycling. Miniaturization Strategy
Modular Waste-to-Energy (WtE) Plants: Companies like Fireprint offer scalable and versatile modular plants.
They are designed for increased availability, reduced staffing, and lower operating costs, with a lifespan of up to 30 years.
This speeds up construction, improves quality control, and allows large components to be built off-site and then assembled on the artificial island.
