WASTE FUEL INCINERATION SYSTEM Abstract A waste fuel incineration process and system operates at very high temperatures with excess under fire air for high efficiency combustion of waste as a fuel and for decomposition of any toxic waste. The system is applicable for clean burning volume reduction of waste and for power generation and co-generation of heat. The control elements are constructed and arranged and the control circuit programmed for maintaining the primary combustion temperature at a target temperature selected in the range of approximately 1600°-1800°F (871°-982°C), for turning on and increasing under fire air to bring the primary combustion chamber flue gasses up to the target temperature, for maintaining the volume rate of flow of under fire air at 150% to 250% of the stoichiometric requirement for complete combustion at normal load, for reducing and turning off under fire air in a first over- temperature range extending above the target temperature, for turning on and increasing over fire air for diluting and cooling flue gasses in a second over-temperature range extending above the first over-temperature range, and for shutting down the under fire air, over fire air and waste fuel feeding cylinder and piston at a selected absolute over-temperature. A variety of safety features are disclosed including a normally closed dump stack on the secondary tower which automatically opens for natural by pass drafting in the event of power failure or excess temperature in the pollution control device. A live "V" shaped gravel bed and ash ram permits removal of slagged gravel for renewing the surface of the hearth.
