Title:
MIXING PART UNIT
Document Type and Number:
Japanese Patent JP3429460
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mixing part unit capable of affording uniform premixed gas obtained by sufficiently mixing combustion primary air and fuel gas.
SOLUTION: There are provided a plurality of combustion primary air intake ports 28 provided in parallel at an interval and a plurality of fuel gas intake port 14 provided in parallel at an interval. The fuel gas intake port 14 is provided to face a negative pressure zone formed in a non-opening section 29 located between the combustion primary air intake ports 28, 28 with the aid of primary air. Diffusion means is provided in the non-opening section 29 for diffusing fuel gas. The diffusion means is an inclination member provided in the non-opening section 29 slantingly for fuel gas to collide. The inclination member is formed by inclining the non-opening section 29 as described above. When the combustion primary air and the fuel gas intersect, the inclination member 29 is inclined within the range of from 10 to 60° with respect to a fuel gas stream.
