AI Technical Summary
Existing technology directly blows air into the combustion furnace through a fan to aid combustion. However, the insufficient oxygen content leads to incomplete combustion, producing unburned particulate matter and harmful gases, which pollute the environment.
A plasma oxygen supply machine is used, which uses a plasma generator to generate a high-voltage electric field to ionize the air and generate ozone. The ozone is then mixed and sent into the combustion furnace, where it decomposes into oxygen at high temperature, thereby increasing the oxygen concentration in the combustion furnace.
Increasing the oxygen concentration inside the combustion furnace ensures complete combustion, reduces the generation of particulate matter and harmful gases, and improves environmental performance.

A plasma positive electrode 8 is arranged in the first conical flow guide 2, and a plasma negative electrode 9 is arranged in the second conical flow guide 3, the plasma positive electrode 8 and the plasma negative electrode 9 are respectively electrically connected with the plasma generator 4 through wires 10, and the plasma generator 4 is used to generate a high-voltage electric field to ionize air.
[0020] Before work, the plasma oxygen supply machine is installed on one side of the combustion furnace, so that the air outlet 7 is in communication with the air inlet of the combustion furnace; and the fan 1 and the plasma generator 4 are respectively connected with power supply.
[0021] In operation, the plasma positive electrode 8 and the plasma negative electrode 9 ionize the air in the first conical flow guide 2 and the second conical flow guide 3, and the ionized air generates ion flow and ozone; at this time, the fan 1 works to make the external air flow into the first conical flow guide 2 and the second conical flow guide 3 through the air inlet 6, and the air mixed with the ozone generated by ionization flows to the air outlet 7, and then flows into the combustion furnace through the air outlet 7. When the ozone meets the high temperature in the combustion furnace, it will decompose into oxygen, so that the oxygen concentration in the air injected into the combustion furnace is increased.
