ABSTRACT:
It is an object of the present invention to provide a pulse combustion method and a valveless pulse combustor in which the strong sound wave energy and the combustion gas generated by explosions in the combustion chamber are effectively used for drying of a substance with no waste of sound wave energy and heat of the combustion gas.
A pulse combustion method according to the present invention is characterized by a step of pushing the sound wave energy and the combustion gas which flow toward the air intake back to the combustion chamber by jetting a compressed gas toward the air intake. By means of this step, the sound wave energy and the combustion gas which were generated at the time of explosion in the combustion chamber and flow toward the air intake are pushed back to the combustion chamber and further to the exhaust pipe by a stream of the compressed gas. This enables the sound wave energy and the combustion gas which have been conventionally wasted to be used for drying of a substance.
