A double-vault kiln self-cooling spray gun system
By using a self-cooling spray gun system, which utilizes a low-oxygen tube to cover the fuel and a heat dissipation tube to cool the gas, the problem of short service life of the gas spray gun is solved, and the high-temperature resistance and service life are improved, thus ensuring production stability.

Abstract
This utility model relates to the field of double-chamber kiln spray lance technology, specifically to a double-chamber kiln self-cooling spray lance system. The system includes a self-cooling spray lance, comprising a fuel pipe, a low-oxygen pipe sleeved outside the fuel pipe, and a heat dissipation pipe sleeved outside the low-oxygen pipe. The fuel pipe is used to transport fuel; the low-oxygen pipe is used to transport low-oxygen or oxygen-free gas; and the heat dissipation pipe is used to transport cooling gas. The fuel sprayed from the lower end of the fuel pipe is the fuel to be burned, and the low-oxygen or oxygen-free gas is sprayed from its lower end through the low-oxygen pipe to coat the outer periphery of the fuel to be burned, thereby causing the fuel to move away from the lower end of the self-cooling spray lance before combustion. This utility model can significantly improve the high-temperature resistance of the self-cooling spray lance, reduce heat loss, and extend its service life.
