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 cone jet device that matches its shape. The device includes a cone 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 adjustment valve hand wheel 6, the cone diameter adjustment valve 4 can be lifted or lowered, thereby controlling the air flow ejected from the nozzle 2, so that it can be kept in an ideal closed cone 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 tube 1 and the...

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 a special burner of internal-combustion blast furnace coal gas which configured the taper fluidic device. It resolves the problem that today's blast furnace coal gas can't be emblazed at normal temperature and is prone to be extinguished. It also has logical configuration and easy to be used. It can make blast furnace coal gas emblazed and keep burning at normal station, with a frame of : nozzle installed at one end of the burning tube, the copulate taper fluidic device installed in the burner, corresponding that device the burning tube should set at least one air hole.

Description

technical field [0001] The invention relates to a combustion nozzle, in particular to an internal combustion blast furnace gas special burner with a cone 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. The rising international oil price has a great impact on the cost production and profit of enterprises. 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 ...
