description The utility model relates to a fuel gas supply device for an electric porcelain tunnel kiln. The fuel gas supply device comprises a high-pressure fuel gas pipe and delivery pipes in three regions, wherein the delivery pipes in the three regions are connected with the high-pressure fuel gas pipe through four-way pipes; each delivery pipe in the three regions is provided with a decompression device, a pressure gauge, a pressure transmitter and an annular pipeline in turn; and a spray nozzle is arranged on each annular pipeline. In the fuel gas supply device, the same pressure is supplied to the same region according to different fuel gas pressures required by a preheating region, a strong reduction region and a high-temperature region of a reduction baking tunnel kiln, so that the baking atmosphere of each region is ensured. Different fuel gas pressures are supplied to the preheating region, the strong reduction region and the high-temperature region in the tunnel kiln, namely high-pressure fuel gas is decompre
