Abstract
A combustion apparatus ( ) is generally composed of a principal part ( ), a supplementary part ( ) and a burner port assembly ( ). Four metal plates ( ) constituting the principal and supplementary parts ( ) are pressed to have in them several protuberances and recesses. These metal plates are laid one on another to form in them some hollow spaces and sealed regions. These hollow spaces communicate with each other to form a thin gas passage ( ) together with a thick gas passage ( ) in this combustion apparatus ( ) in such a manner that its condition of thick and thin fuel combustion is rendered more stable.
