Combustion equipment of a coaxial jet combustion scheme is provided that includes: a burner plate (11) in which fuel and air are mixed with each other while the fuel and air pass through an air hole (12); a burner plate extension which is a portion of the burner plate (11) and extends toward a combustion chamber side spaced apart from the air hole (12); and a protrusion (1) disposed on the combustion chamber side of the burner plate extension so as to protrude in a direction where flow of the fuel moves. In the combustion equipment, a gap between opposite portions of the protrusion (1) is greater than a diameter of the air hole (12) and a flame source forming area is defined between the burner plate (11), the burner plate extension and the protrusion (1). The combustion equipment of a coaxial jet combustion scheme can achieve a further reduction in NOx emissions.
