This application relates to the field of combustion and environmental protection, in particular to a carbon dioxide and oxygen gas mixing device and a mixed gas combustion-supporting pollution gas zero-emission system. Since the gas participating in the combustion-supporting gas is a mixture of oxygen and carbon dioxide, oxygen participates in combustion to generate carbon dioxide when fully burned. The content of carbon dioxide in the tail gas is quite high, which can reach more than 95%, so it greatly reduces the difficulty of recovering carbon dioxide, reduces the cost of recovering carbon dioxide, and also greatly reduces the emission of carbon dioxide and reduces the impact on the atmosphere. At the same time, because the gas involved in the combustion is a mixture of oxygen and carbon dioxide, it also avoids a large amount of nitrogen from participating in the combustion, thereby avoiding the emission of nitrogen oxides, thereby reducing the pollution to the atmosphere.
