The harmless incineration treatment of domestic garbage and industrial waste, the promotion of incineration efficiency, the means of recycling combustion heat and the like are always research hotspots in the technical field of environmental protection.

As is well known, when the combustion of materials is insufficient, on one hand, the combustion efficiency of the materials is greatly reduced; on the other hand, since the oxygen supply is insufficient, toxic gases such as carbon monoxide are easily generated. The current device that burns ubiquitous insufficient problem of burning, its reason is summarized in the analysis mainly includes: firstly, the total oxygen supply in the incinerator is insufficient. The flow of the air introduced into the furnace is small; secondly, the oxygen distribution in the incinerator is uneven. The blast channels of most incinerators are arranged unevenly, so that oxygen in the incinerator is distributed unevenly; thirdly, accurate feeding is not achieved. When the materials are incinerated, the oxygen consumption at each position in the incinerator is different due to different combustion degrees of the materials at different positions; fourthly, the ash covers the substances to be combusted to prevent the substances to be combusted from contacting with oxygen.
