A regenerative thermal oxidizer was applied to the processing of exhaust gas from a mud incinerator, and the stack CO concentration of 100 ppm or less which depends on dioxin regulating methods was attained. 92% or more of a heat recovery rate was attained through heat exchange using a regenerator. And, a dramatic reduction in fuel costs was achieved. Moreover, an examination was carried out to process tar contained in exhaust gas and a stable operation was achieved.
