Multiport Perforated Refractory (PR) burners have multiport burner screens that break up the flame into a large number of small flames. This results in a concentrated “flat face,” round flame of high intensity. The screen port diameter/length ratio is selected to inhibit flashback even at extremely low input rates. The screen retaining-ring effectively pilots flames to prevent flame blowoff under normal operating conditions. The burner design incorporates one-piece construction with interchangeable components, simplifying replacement of damaged parts. It can be installed individually or in groups and can be mounted in any position to standard pipe fittings or manifolds.
