Embodiment 1

[0021] In Fig. 1, the blast furnace gas pipeline 1 is connected with one end of the nozzle 2, and the other end of the nozzle 2 is placed at one end of the combustion tube 1, and the other end is the outlet of the flame. The nozzle 2 has a built-in prism body jet device matching its shape, which includes a prism body diameter adjustment valve 4, which is connected to the diameter adjustment valve joystick 5, and the top end of the diameter adjustment valve joystick 5 is connected to the diameter adjustment valve handwheel 6. By turning the diameter-adjusting valve handwheel 6, the truss body diameter-adjusting valve 4 can be lifted or lowered, thereby controlling the airflow ejected from the nozzle 2, so that it can be kept in an ideal closed prism body air curtain.

[0022] In order to ensure sufficient mixing of gas and combustion-supporting air, several air holes 3 are arranged along the circumference on the peripheral wall corresponding to the position of the combustion tub...

Embodiment 2

[0024] In this embodiment, different from the first embodiment, there are several air holes 3 , which are arranged on the circumferential wall corresponding to the position of the nozzle 2 .

Embodiment 3

[0026] In this embodiment, different from the first embodiment, the air hole 3 is a gap between the combustion tube 1 and the nozzle 2 .

Abstract

The invention discloses internal fire type blast furnace gas special burner nozzle with prismatic table body fluidizing device. It has the advantages of reasonable structure, convenient using, and normal firing. Its structure is as follows: it has nozzle set at one end of burner tube, and in which is set matching prismatic table body fluidizing device; and the burner tube is set at least one air hole at corresponding place.

Description

technical field [0001] The invention relates to a combustion nozzle, in particular to an internal combustion blast furnace gas special burner with a frustum body jet device. Background technique [0002] With the rapid development of the national economy, the energy consumption of iron and steel enterprises is also increasing day by day. Therefore, finding a good way to replace petroleum products with blast furnace gas (called blast furnace waste gas in the past) is a major event that benefits the country and the people. [0003] For a long time, our country has been constantly exploring the method of rational utilization of blast furnace gas. However, due to the unreasonable structure of the traditional burner, the gas and combustion air are mixed after leaving the burner and the mixing is uneven, which affects the chemistry of fuel and air. reaction. Therefore, it is easy to produce the phenomenon of flameout and extinguishment, and it is difficult to ignite. In additio...
