This burner has lower radiant velocity than a typical pre-mix gas-fired infrared burner. As an atmospheric burner, the heat output of the AB-7 is 700 btu/hr/linear inch or 190 btu/hr/square inch at the inspirator inlet gas pressure.
- fuel source can be either propane or natural gas
- excellent choice for process applications where less intense infrared radiation is needed, such as plastic thermoforming
- No Electric Power Required: Because it does not require an electric blower to operate, the AB-7 is used in a number of applications where portability and compact size are important, such as thermoplastic striping equipment for highways and roadways
- also commonly used for heating and cooking foods, as well as in commercial and residential BBQ grills
The special ceramic refractory grid used in the AB-7 burner has hundreds of small ports through which the gas flows. The gas ignites as it exits these holes, producing no visible flame. However, an infrared glow can be observed between the top of the refractory grid and its reverberatory screen, which acts as an additional radiant body.
- high quality materials including cast iron bodies, stainless steel internal components and hold down rails
- available in a corrosion resistant nickel plated construction for applications in harsher environments
By operating at recommended firing pressures, the possibility of burn-back or flashing is greatly reduced. The orifice size for the inspirator is dependent upon the number of burner sections on the manifold. The greater the number of sections, the greater the orifice size (see the selection table). Typically, a two section burner is used. Larger burner arrays require special manifolding, such as multiple inlets.
For higher temperature operation, the AB-7 burner can be used in a premix system (aspirator mixer and gas regulator) to increase the heat output to 1,000 btu/hr/linear inch. Contact Red-Ray for further details on outputs of both atmospheric and premix burner systems.
