To provide an inexpensive heating, heat generation and heat supplying device, which comprise sufficient heat efficiency to be substituted for petroleum resources to get out of dependency on petroleum resources, and is free from a problem on environmental pollution.

As a lower edge of a partitioning member 10 is positioned near a burning point P, the partitioning member 10 composed of a ceramic material is constantly kept in a high-temperature heated state by continuous burning of cokes, thus the inside of an exhaust passage 8 is heated by the partitioning member 10 composed of the ceramic material kept at high temperature, a temperature of a heated gas passing through inside of the exhaust passage 8 and discharged from an exhaust port 9 is lowered little even in a process of passing through the inside of exhaust passage 8, and a remaining unburned component is reburned in the process of passing through the inside of exhaust passage 8 kept at the high temperature, and discharged from the exhaust port 9 as a clean gas.
