INCINERATORS, AND GASIFIERS AND BURNERS FORMING PART OF SAME A B S T R A C T A gasifier for generating a producer gas output from a cellulosic waste material input has an axially aligned top fuel feed down onto a conical grate with provision for removing fuel pile ash from around the base perimeter of the grate. A preferred embodiment includes means for adjusting the fuel feed above the leve of the grate and to control underfire admission air from beneath the grate so as to control the fuel pile size. An annular top opening is provided for guiding producer gas from the chamber. A producer gas burner has a cyclonic combustion chamber with an upper inlet for spirally directing producer gas down into the cham- ber and secondary combustion air inlet means at the lower end of the chamber for directing secondary air tangentially and upwardly into the chamber. An exhaust outlet is disposed at the lower end of the chamber with an exhaust inlet axially aligned with the chamber. In a preferred embodiment, the gasifier and burner are com- bined using a double scrolled duct to transport producer gas from the gasifier to the burner, and the gasifier and burner share a common ash removal system.
