<P>PROBLEM TO BE SOLVED: To provide a thick and thin combustion burner capable of levelling the density and/or supply amounts of thick air-fuel mixtures supplied to a plurality of thick burner ports. <P>SOLUTION: A thick burner port array 33, thin burner port arrays 34, 34, and thick burner port arrays 35a, 35b are arrayed in order at a central part at both sides and at both outer sides. A lower end 60 of a central thick burner 3a is protruded into a cylinder 38 into which the thick air-fuel mixture is introduced, and communication holes 61, 61 are formed at both side walls. Communication holes 41, 41 communicating with the outer side thick burner port array 35a or 35b are opened into the cylinder 38. The communication holes 61, 61 are formed to have opening areas equal to that of the central thick burner port array 33, and the communication holes 41, 41 are formed to have opening areas equal to that of each of the outer side thick burner port array 35a or 35b. They may be formed to have the opening areas smaller than that of each thick burner port by multiplying each by a predetermined reduction rate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
