<p>PURPOSE:To provide a varporization combustion burner that is capable of starting vaporization combustion in a short time and short distance after ignition. CONSTITUTION:The subject vaporization combustion burner is provided with an inner cylinder 10 for combustion, outer cylinder 20 for holding flame, and fuel spraying nozzle 30, and said inner cylinder 10 for combustion is formed of the small diameter cylindrical section 11 that is opposite said fuel spraying nozzle 30, connecting section 12 connected to this small diameter cylindrical section 11 and large diameter cylindrical section 13. Said outer cylinder 20 for holding flame is placed coaxially on said inner cylinder 10 for combustion, the difference between the outer diameter of the outer cylinder 20 and that of the inner cylinder 10 being equal to or smaller than the difference between the outer diameter D1 of the large diameter cylindrical section 13 and the outer diameter D2 of the small diameter cylindrical section 11, and at the same time at the end of the outer cylinder for holding flame a bend section 21 that covers the end of the large diameter cylindrical section 13 of the inner cylinder 10 for combustion is provided with a flow gap C, and in the circumferential wall section of the small diameter cylindrical section 11 of the inner cylinder 11 for combustion open sections 14 in a required number are provided.</p> |
