AbstractA mixing unit consists of a plurality of combustion primary air intake ports provided in parallel at an interval and a plurality of fuel gas intake port provided in parallel at an interval. The fuel gas intake port is provided to face a negative pressure zone formed in a non-opening section located between the combustion primary air intake ports, with the aid of primary air. The non-opening portion contains a fuel gas diffusing device and the fuel gas diffusing device is in a slant state to make fuel gas collide with the non-opening portion. Thus, the non-opening portion is in 10 to 60 degrees when the combustive first air and the fuel gas are orthogonal with each other. This invention provides a mixing part unit capable of affording uniform premixed gas obtained by sufficiently mixing combustion primary air and fuel gas.
