Environment-friendly high-temperature-resistant kiln furniture capable of reducing nitride emission and preparation method thereof

The invention relates to the field of kiln furniture, in particular to environment-friendly high-temperature-resistant kiln furniture capable of reducing nitride emission and a preparation method of the environment-friendly high-temperature-resistant kiln furniture. In order to solve the technical problems that a combustor is difficult to achieve high combustion efficiency and the proportion that nitrides discharged by combustion cannot be completely combusted is greatly increased when the quantity of flames released by the combustor is reduced, the environment-friendly high-temperature-resistant kiln furniture capable of reducing nitride emission comprises an auxiliary combustor, a gas collecting pipe and the like; the middle of each auxiliary combustor is fixedly connected with a gas collecting pipe. Combustion-supporting gas is guided into the gas collecting pipe through the main combustor, nitrogen-containing gas which is not fully combusted by the main combustor is collected into the gas collecting pipe
