PROBLEM TO BE SOLVED: To provide combustion equipment which does not cause such a failure that no appropriate catalytic reaction is obtained in a catalytic combustion section 6 on the downstream side of a premixing chamber 14 due to the uneven supply of vaporized fuel between the inside and outside of the chamber 14 when the vaporized fuel is made to be supplied from the inside of the chamber 14. SOLUTION: This catalytic combustion equipment is provided with an expanded chamber container 101 in almost whole upstream-side area of the premixing chamber 14. To the internal space A of the container 101, the vaporized fuel vaporized by means of a vaporizer 7 is supplied. Many nozzle holes 102 are made through the wall of the container 101 facing the combustion section 6 in such a way that the diameters of the holes 102 becomes smaller as going toward an evaporating pipe 30 provided at the center of the container 101. The vaporized fuel supplied to the internal space A of the container 101 is discharged to the whole area of the premixing chamber 14 through the holes 102 and becomes a mixed gas having a uniform concentration distribution. Consequently, the mixed gas having a uniform mixing ratio can be supplied to the combustion section 6 and an appropriate catalytic reaction can be obtained in the whole area of the section 6.
