The invention relates to a secondary air premixed gas burner for a ceramic kiln. The burner comprises a shell, a gas pipeline, a secondary air inlet pipeline and a burning nozzle, wherein the gas pipeline and the secondary air inlet pipeline are coaxially arranged at one end of the shell; the gas pipeline is positioned inside the secondary air inlet pipeline; one end of the gas pipeline extends out of the secondary air inlet pipeline and enters an inner cavity of the shell; a gap is formed between the secondary air inlet pipeline and the gas pipeline to form a secondary air inlet channel; the secondary air inlet channel is communicated with the inner cavity of the shell; and the burning nozzle is arranged at the other end of the shell. An ideal air fuel ratio can be achieved before combustion air is mixed with gas through the secondary air inlet pipeline, and the burner contributes to fully burning the gas, saving energy and reducing emission. During use, the secondary air premixed gas burner for the ceramic kiln can be taken out of the ceramic kiln so as to adjust the air fuel ratio, the burner is arranged in the ceramic kiln after the requirement is met, and the burner is simple and practicable in operation.
