INCINERATION FURNACE, STEAMING AND MELTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To enhance complete combustion efficiency by providing a combustion furnace body or a steaming/melting apparatus body having a combustion furnace chamber or a steaming/melting chamber being kept airtightly with a pressure increasing and/or decreasing means thereby suppressing or preventing generation of pollutants at the time of heating a heating chamber. SOLUTION: In a combustion furnace body or a steaming/melting apparatus body having a combustion furnace chamber or a steaming/melting chamber being kept airtightly, the steaming/melting apparatus is a steaming and boiling apparatus including a fusing or melting apparatus or the furnace thereof. The combustion furnace body 1 is fixed with an enclosing cover, a passage 5 is provided at a lower part of the combustion furnace. A lifting/floating valve for regulating pressure and serving as a safety valve is provided in the passage 5. When the pressure is high, that valve lifts to regulate the pressure and the valve normally descends to block the passage. A forward/reverse action pump 3 is provided in the extension of the passage in order to regulate pressure in the combustion furnace chamber.
