The incineration method oxidizes the combustibles in the garbage into carbon dioxide and water through high-temperature oxidation, and simultaneously releases heat energy to discharge the flue gas and solid residue. The incineration method has a high degree of reduction, a short treatment cycle, a small footprint, flexible site selection, and can decompose and destroy harmful and toxic wastes. The heat generated by the incineration process can be used to generate electricity to realize the energyization of waste.
By incineration, flammable solid waste can be oxidatively decomposed and generate heat to remove toxicity, recover energy and obtain by-products. Almost all organic waste can be treated by incineration. For inorganic-organic mixed solid waste, if the organic matter is a toxic and harmful substance, it is generally treated by incineration.
Incineration treatment has certain requirements on the low calorific value of garbage, so not all garbage can be incinerated, and only for those garbage that can not recover valuables and can only recover heat, garbage incineration treatment is scientific and reasonable.
The use of resources in garbage is destroyed, which is a waste of resources. Even if the heat is recovered, it can only achieve the purpose of one-time regeneration of waste, and it is impossible to achieve multiple recycling of resources. The large amount of smoke generated by incineration, and the heat taken away is a big loss. The generated flue gas must be purified, and the purification technology is difficult and the running cost is high. The residue from incineration must also be digested. In addition, incineration equipment has a large investment and high operating costs.
