A self-regenerative combustion system comprising a single burner, capable of operating both during the combustion step and the waste gas aspiration step, and a valve with four ways and three positions, capable of switching the regeneration and the on/off control (oxydizing agent end and waste gas end). The system is provided for obtaining the maximum efficiency, flexibility, minimum fuel consumption and minimum environmental impact with reduced NOx emissions.

Disclosed herein is a combustion apparatus which comprises a chamber having a apertured rotatable tubular auger mounted between end walls of the chamber to convey particulate material from the region of the chamber proxi-mate the feed inlet to the combustion gas outlet and a blower connected to the opposite end of the tubular auger and configured to blow gas into the bore of the auger and out through the apertures into the chamber.

Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.

A waste incinerator, in a vertical structure and including from the top down: a drying section, a destructive distillation section, a reduction section, and a combustion section. The combustion section includes: two layers of grate bars, a first combustion layer, a second combustion layer, and a third combustion layer. The heat produced from the combustion in the combustion section is used to heat the carbide in the reduction section. The heated carbide reduces CO.sub.2 produced in the combustion into CO (coal gas). The coal gas ascends to the destructive distillation section through the ambient coal gas chamber to heat and destructively distillate the waste to produce the pyrogenic coal gas and the carbide. The carbide drops to the combustion section for combustion, and the pyrogenic coal gas and the coal gas are collected by the draft fan.

The system fulfills the requirements for safety with its active opening device and with its two levels of different independent mechanical protections against overpressure including a BD with block valves and the BPV without any block valves.
