| BENEFITS |
The Flat Flame Burner has a flared refractory outlet which produces a disc-shaped flame which "sticks" to the refractory wall or roof, thus creating a source of radiant heat. It is used in applications where no forward velocity can be tolerated.
Typically these are kilns where the flame cannot be allowed to impinge on the ware, or large reheating furnaces, where they are installed in the roof to ensure good temperature uniformity by providing additional heat in the middle of the furnace. FFB Burners are also used for reheating glass sheets prior to bending.

TURN DOWN ANDEXCESS AIR FACILITY |
The diameter and radiation of the disc-shaped flame are controlled by the turndown and the amount of excess air, respectively. The maximum turndown of the FFB Burner is more than 10/1 and the maximum excess air is 1500%
|
| FUELS |
The FFB Burner is suitable for natural gas, LPG and gas oil with a viscosity of 34 sec. Red. 1.
|
| IGNITION AND FLAME SUPERVISION |
The FFB Burner can be ignited by means of direct spark when operating on natural gas or LPG and by premix pilot when operating on oil. The burner is fitted with a sight glass and a port is provided for a UV scanner to be installed. In order to start the burner automatically and supervise the flame permanently, Hotwork Combustion Technology can also supply flame management equipment if required.
|
| HOT AIR VERSION |
In order to improve fuel efficiency, Hot Air Flat Flame Burners for preheated air up to 550 ° C are also available for applications where a central recuperator is fitted such as reheating furnaces.
