PURPOSE: A combustion apparatus having improved airflow is provided to increase combustion power by forming restrictive paths of airflow between chambers, and efficiently communicate airflow between the chambers without using a plurality of fuel lines. CONSTITUTION: A gas combustion-powered apparatus is composed of a first chamber, a rotatable fan located in the first chamber, an ignition unit interlocked with the first chamber to ignite a combustible gas, a second chamber(58), first communication units between the first chamber and the second chamber and downstream of the fan(24), at least one intake port located on a wall of the first chamber upstream of the rotatable fan, and at least one bypass port(52) separated from the first communication units and located on the wall of the first chamber downstream of the rotatable fan. The first communication units is constructed and arranged for enabling passage of an ignited gas jet from the first chamber to the second chamber.
