This study is the development the new concept of the low-NO_X combustion system advanced from the tube-nested combustor, in which air is supplied from the porous cylinders by the transpiration. The porous cylinder array, which is placed in the furnace closely to the burner, enhances the combustion and the transpiration air brings about the multi-stage combustion leading to NO_X reduction. Two types of cylinders are used for the air supply, one is the porous cylinder and the other is the jet cylinder, which has small holes on the solid cylinder surface. In the case of the single jet cylinder, the combustion range is wider than that in the porous cylinder array and the CO concentration of the exhaust gas is enough low because of the good mixing condition. The NO_X concentration is able to be reduced by optimizing the cylinder arrangement of the jet cylinders.
