(JP2000038590-A)      NOVELTY - An air introduction board (41) is distributed to the upper portion of a heater body. The air introduction board has an air supply port (46) provided to the upper portion of the chamber, to form an air inlet (44). The supply port is opened and closed to control and allow supply of air to the lower portion of the combustion chamber.    DETAILED DESCRIPTION - End of a heater body (11) is connected to exhaust chimney (14) leading to exhaust exit (13). A combustion chamber (21) with an upper vent, is formed within the heater body. Stay combustion of smoke generated from the solid fuel (F) of waste plastic subjected to pulverization, compression, solidification.    USE -   For use in industrial plant, business establishment.    ADVANTAGE -   Generation of incineration ashes is decreased effectively. Life prolongation of ultimate disposal of solid fuel is achieved. Recycle industry of the waste plastics in the generating business establishment, is promoted. Comprehensive design control and service management are also enabled.    DESCRIPTION OF DRAWING - The figure shows sectional view of combustion equipment. (1) Combustion equipment; (11) Heater body; (13) Exhaust exit; (14) Exhaust chimney; (21) Combustion chamber; (41) Air introduction board; (44) Air inlet; (46) Air supply port.
