Abstract

A combustion system automatically controls the combustion air intake rate at a predetermined value by an induced fan through an air inlet of a combustion apparatus in accordance with the furnace temperature. The combustion system includes a combustion gas circulating system independent of the system for feeding high-temperature air for vaporizing the moisture and gasifying the volatile components in the materials to be burned or for initially burning the materials through the bottom of the furnace. A combustion furnace for use in this system is also disclosed.
