<p>A dual-purpose combustor for ordinary combustion and pulse combustion especially suited to be installed for a spray dryer, which is used not only as an ordinary combustion gas generator but also as a pulse combustion gas generator capable of generating high frequency sound waves and hot blast in large capacity to enhance the drying efficiency. The dual-purpose combustor is composed essentially of successionally connected chambers, i.e. a concentric narrow ring form fuel/combustion air mixed gas supply slit (2), a concentric wider ring form combustion chamber (3) having an ignition means (41) and a narrow outlet portion(4), a concentric narrow ring form exhaust gas chamber (5), a concentric wider ring form upper secondary combustion chamber (6), and a concentric cylindrical form lower secondary combustion chamber (7) having the same diameter with the outer diameter of the concentric ring form upper secondary combustion chamber (6). <IMAGE></p> |
