Domestic industrial low emission high performance gas burner for use on a variety of heating applications

Product Overview

Description

The HEATFLAM burner is a nozzle-mixing, medium velocity burner. It provides a stream of hot combustion gases that promote circulation within your furnace, improving both temperature uniformity and workload penetration.
The air/fuel mixing design allows for the burner to be operated on ratio throughout the firing range, with excess air up to 4700% for some sizes or with excess fuel.
Series HEATFLAM Burners are designed to operate on natural gas, propane or butane but can burn other gaseous fuels as well.

 

FEATURE

Exit velocities up to 275 ft/s (190 miles/h) to promote workload heat penetration and better furnace temperature uniformity

Operate on-ratio, with excess fuel or with excess air to meet the specific demands of your combustion process needs

Burns most clean, low pressure gaseous fuels or light oil 

Turndown capability up to 48:1

Maximum application flexibility with 7 different sizes and maximum capacities ranging from 0.38 MBtu/h up to 8.4 MBtu/h

Lower fuel consumption using preheated combustion air (up to 800 °F) Refractory block for chamber temperatures up to 3000 °F

Removable backplate, providing access for easy inspection and/or maintenance

HEATFLAM burners can be used with oxygen enriched combustion air

 

Combustion air enters the burner body and is swirled out into the burner block through the internal air orifice plate. Low pressure gas enters the burner body and exits to the block through machined ports in the gas nozzle.
The gas and air are intimately mixed in the cast burner block tunnel. The spark ignitor is positioned to intersect the fuel/air mixture directly in front of the nozzle face.
Pilot gas is introduced directly behind the gas ports in the gas nozzle and essentially flows through to the burner block through the same ports as does the main gas. The pilot capacity is the minimum firing rate of the HEATFLAM burner.

Typical burner data Fuel: natural gas with 1000’s Btu/ft³ HHV - sg = 0.6 [1] Combustion air: 60 °F - 21% O2 - 50% Humidity - sg = 1.0 [1] Stated pressures are indicative. Actual pressures are a function of air humidity, altitude, type of fuel and gas quality

APPLICATIONS
HEATFLAM burners are designed to be used in high temperature furnaces. They are commonly applied on heat treatment furnaces, oxidizers, melting furnaces, ceramic furnaces and other high temperature applications.
