PREPARATION OF DOWNWARD PLASMA PYROLYSIS MELTING FURNACE FOR DISCHARGING EXHAUST GAS

摘要

PURPOSE: Preparation of a melting furnace is provided to prevent tar from being generated by discharging pyrolysis gas downward and to reduce the danger of gas explosion of a reaction furnace. CONSTITUTION: A pyrolysis gas passes through waste matter in the air to flow into a pyrolysis reaction area. Heat is exchanged between the gas and the waste matter in the waste layer so the temperature of the waste matter as to rise. Thus, partial pyrolysis is performed and a reaction furnace does not avoid the low-temperature pyrolysis reaction. Carbon of hydrocarbon increases through the pyrolysis reaction at a low temperature and tar including oil is generated at the normal temperature. The tar causes the dangerous situation of exploding the pyrolysis gas material. A pyrolysis melting furnace reduces the tar and increases the CO content by directly discharging the pyrolysis gas.
