Underfeed and reverse-burning type burner

Abstract

The invention relates to an underfeed and reverse-burning type burner having the advantages of more complete fuel burning and cleaner exhausted flue gas. The underfeed and reverse-burning type burner comprises a box body, fuel conveyors and a blower device, wherein a grate is arranged in the box body; fuel troughs are arranged in the middle of the grate; an air chamber is formed by space between the outer side surface of the grate and the inner side surface of the box body; an annular partition board is further arranged in the box body, and the upper surface of the partition board makes contact with the outer side surface of the grate; the part, located above the top surface of the partition board, of the grate is the upper grate part, and the part, located below the top surface of the partition board, of the grate is the lower grate part; the air chamber is divided into an upper air chamber and a lower air chamber by the partition board, the upper air chamber is communicated with the upper grate part, and the lower air chamber is communicated with the lower grate part; an output end of each fuel conveyor extends into the corresponding fuel trough; the blower device comprises a blower and an air delivery pipe communicated with an outlet of the blower, an upper air channel and a lower air channel isolated from each other are formed in the air delivery pipe, the upper air channel is communicated with the upper air chamber, and the lower air channel is communicated with the lower air chamber.

Description

technical field [0001] The invention relates to a combustion device, in particular to a downward feeding anti-combustion type combustion machine. Background technique [0002] As a kind of combustion equipment, the burner is widely used as a heating device for hot stoves, boilers and other equipment. The fuel of the existing burner is added from the top, and the fuel is generally burned from the bottom to the top. The volatile matter in the upper fuel is easy to produce The phenomenon of incomplete combustion reduces the utilization rate of fuel. At the same time, due to incomplete combustion, there are more fixed carbon particles in the flue gas generated during the combustion process, which makes the flue gas darker, thereby causing certain pollution to the environment. [0003] In view of the above-mentioned defects, the designers are actively researching and innovating in order to create a burner with a new structure, so that it has more industrial utilization value.

[0002] As a kind of combustion equipment, the burner is widely used as a heating device for hot blast stoves, boilers and other equipment. The fuel of the existing burner is added from the top, and the fuel is generally burned from the bottom to the top. The volatile matter in the upper fuel is easy to produce The phenomenon of incomplete combustion reduces the utilization rate of fuel. At the same time, due to incomplete combustion, there are more fixed carbon particles in the flue gas generated during the combustion process, which makes the flue gas darker, thus causing certain pollution to the environment.
