Description

Airflow device for burner

The present invention relates to an air direction device, in particular to an air direction device of a combustion furnace.

Please refer to Figure 1. The current burner refers to a large or small gold paper stove or an incinerator for burning objects to be burned. The current combustion furnace is illustrated by taking the small gold paper stove 1 as an example. The small gold paper stove 1 includes a furnace body 11 and an upper cover 12 covered on one end of the furnace body 11 , wherein the furnace body 11 has a furnace body 11 inside. A combustion chamber 111 and an exhaust gas outlet 112 that can pass through one end of the combustion chamber 111 for objects to be combusted (such as gold paper, etc.) Gold paper, etc.) are put into the combustion chamber 111 for combustion, and a plurality of ventilation openings 14 are distributed on the furnace wall surface 13 of the furnace body 11, and most of the oxygen required for combustion is entered through the exhaust gas outlet 112, and Part of the oxygen enters the combustion chamber 111 through the vents 14 . Because burning gold paper requires a large amount of oxygen to make the gold paper burn quickly, and a large amount of oxygen enters through the exhaust gas outlet 112 and the vents 14 at the same time, so that the gold paper can be burned. However, there is a large amount of gold paper in the combustion chamber 111 of the existing small gold-paper stove 1, and the oxygen supply of the gold paper in the lower layer of the combustion chamber 111 by the vents 14 under the furnace body 11 is slightly insufficient. , it is easy to reduce the combustion efficiency of gold paper. Therefore, the user often takes a long rod and turns the unburned gold paper into the combustion chamber 111. When the gold paper often smolders, the combustion efficiency is low, and it is easy to generate exhaust gas such as soot and carbon monoxide. It will cause the problem of polluting the air and the environment, and there will be a lot of unburned gold paper ashes. Usually, the ashes need to be poured out, which will easily affect the pollution of the secondary environment. Therefore, the existing small gold paper stove 1 lacks a lot. Therefore, further improvement is necessary.
