摘要
A method and apparatus for burning combustible waste materials such as municipal and other refuse, utilizing combustion of the waste materials in a rotary tubular kiln at temperatures above 1200 DEG C., using combustion air in the temperature range between 300 DEG and 800 DEG C. with a small air excess and a reduced quantity of flue gas. The invention further includes heat transfer from the hot flue gas into the combustion air by means of a heat exchanging solid, whereby the solid is heated in contact with the flue gas and subsequently is cooled in contact with air. This air is heated to combustion air temperature and is conducted to the firing of the rotary kiln. The solid may also simultaneously bond noxious substances in the flue gas.
