WESMAN BURNERS

High Velocity Stationary Burner (Tempest & HIRAM Burner)

In a furnace the re-circulation of products of combustion can substantially contribute to the speed of heating and temperature uniformity. For low temperature ovens and dryers, suitable re-circulating fans are generally provided to achieve temperature uniformity. However, fans are not practical for high temperature furnaces and kilns.

Excess air can help in re-circulation but this will result in wastage of fuel. 30% excess air for a 1100 degree centigrade furnace will require additional 24% fuel than stoichiometric firing. In comparison, high velocity gases entrain and re-circulate more than seven times of own volume will eliminate need for fans or excess air. Tempest and Hiram burners are the answer for such applications.

Flat Flame Gas Burners


Where penetration or forward drive by the flame or combustion gases is to be avoided or when radiation heat transfer is to be enhanced Flat Flame Burners can be effectively used. Flat Flame Burner actually heats its own refractory tile and the refractory surface of a surrounding furnace wall or roof by convection from the high velocity combustion gases thrown sideways from the burner. The hot refractory surface then start to radiate heat to the load. The disc shaped flames produced by these burners have no forward velocity. Flat Flame Burners have been successfully used in enhancing the capacity of reheating furnace by increasing the temperature at the inlet of the furnace.

Application:

• Preheating furnaces
• High Temperature Kilns
• Salt Pots
• Galvanizing Tanks
• Cover Annealing Furnace
• Slab Heaters
• Patenting Furnace
• Glass Annealing Leh

6832 Flat Flame Dual Fuel Burner



Luminous Long Flame Burners (Fire-All)


In some operations a direct flame radiation over a large area is desirable. Luminous long flame (Fire-all) burners have considerable length and they can fill a large volume of combustion space with flame having little temperature variation along their length. This permits more effective use of hearth area because of uniform temperature head through out the combustion space.

• Pre-heated combustion air up to 350 degree centigrade can be used
