[0008]

In the above incinerator, the wastes put into the primary combustion chamber of the combustion furnace body are primarily burned by the appropriate amount of combustion air sucked from the combustion air supply adjusting port to be combusted and gasified.

This combustion gas flows into the secondary combustion chamber of the discharge cylinder. In the secondary combustion chamber, the temperature of the flame from the temperature-raising burner is high, so the combustion gas flowing in the secondary combustion chamber is heated above the flash point and touches the oxygen in the air ejected from the secondary air supply nozzle. Secondary combustion, the carbon dioxide is completely converted to carbon dioxide by the time it reaches the upper end exhaust port, and the soot generated by incomplete combustion is also completely oxidized, and the chemical components that cause odor are also high temperature. It becomes odorless when it is oxidized or decomposed in the atmosphere.

Therefore, garbage such as paper waste, wood waste, waste cloth, and the like,
It becomes possible to incinerate mixed garbage in which a small amount of rubber scraps, plastics, kitchen waste, etc. are mixed with these garbage in a smokeless, odorless, and pollution-free state.

Further, the double steel plate water cooling jacket can be used as a water heater that absorbs heat generated during combustion and uses the hot water generated by this heat absorption.
