Abstract

A single bed thermal oxidizer for oxidizing a contaminate in a gas (air) stream has a plenum above the bed containing burners for gaseous fuel and means for injecting excess air. The burners are activated to initially heat the adjacent top bed portion. The burners are then turned off and a mixture of gaseous fuel and air is passed down into and through the bed which oxidizes the gaseous fuel and transfers the hot portion of the bed downward to preheat the central region of the bed. At that point, the gaseous fuel is terminated and the contaminated gas stream is introduced into the preheated bed for oxidation of the contaminate.
