摘要： Disclosed in the present application are an ammoxidation reactor and a method for producing nitric acid. In the present application, the ammoxidation reactor comprises: a housing and a top cover that covers the shell to form a hearth, wherein the hearth comprises a first space and a second space that are in communication in a vertical direction; a combustion unit, which is located in the first space and comprises a platinum net layer, wherein a combustion reaction is performed with the platinum net layer as a medium until the temperature of the platinum net layer enables ammonia gas entering the hearth to be oxidized to generate a nitric oxide; and a heat recovery unit. The heat recovery unit of the present application allows a high-temperature gas to be successively and uniformly distributed and to pass downwards in sequence, and the high-temperature gas is discharged after a heat exchange from top to bottom and enters a subsequent procedure. The heat recovery unit of the embodiments of the present application can recover heat energy and reduce the influence of a high temperature on the safety and reliability of the ammoxidation reactor.
