Embodiment 1
[0042] Such as Figure 1-Figure 5 As shown, this embodiment discloses a flame denitrification burner device, which includes a flame chamber 8, a combustion head 4, and a material nozzle 5, wherein: the combustion head 4 communicates with the flame chamber 8, and is used to pass into the flame chamber 8. A mixture of fuel and air; the mixture ignites the fuel in the flame chamber and generates high-temperature gas; the flame chamber 8 is provided with a combustion gas outlet 15, and the fuel gas outlet 15 is located at the end of the combustion head 4, and the center of the flame chamber 8 has Through the inner hole, the material nozzle 5 is arranged in the through inner hole of the flame chamber 8 and runs through the flame chamber 8, the material nozzle 5 is used to circulate uranyl nitrate, the outlet position of the material nozzle 5 and the position of the fuel gas outlet 15 are the flame chamber 8 The same end of the same end, so that the uranyl nitrate ejected from the m...
Embodiment 2
[0058] This embodiment discloses a flame denitration fuel device, which differs from the flame denitration burner device described in Embodiment 1 in that it also includes a pressurizing mechanism,
[0059] The pressurizing mechanism is used to pressurize the air before the air is passed into the air chamber 2, so that the air has a relatively high pressure. After the pressurized air enters the flame chamber 8, it will promote the gas in the flame chamber 8 to form a high-speed The rotating high-pressure and high-temperature gas, after contacting the uranyl nitrate ejected from the material nozzle 5, the high-pressure and high-temperature gas will not only heat the uranyl nitrate, but also atomize the uranyl nitrate.
[0060] Moreover, since the device is equipped with a pressurizing mechanism, the material nozzle 5 can be an ordinary material nozzle 5, that is, the material nozzle 5 does not have the function of atomizing uranyl nitrate, but only plays the role of transporting...
Embodiment 3
[0062] This embodiment discloses a flame denitration system, which includes the flame denitration burner device described in Embodiment 1 or 2.
